1 Introduction
AGEs play a pivotal role in the development of chronic age-related diseases such as diabetes, renal failure and cardiovascular disease. The level of AGEs in long­lived tissues (not in blood!) serves as a memory of glycometabolic and oxidative stress and is a valuable predictor of cardiovascular complications.
Until now it has been complicated to measure tissue AGEs in patients because existing methods are expensive, time consuming, lack specificity, are poorly reproducible and/or are invasive. The AGE Reader mu is the answer to the need for measuring AGEs without the disadvantages of the existing methods. This state of the art device provides a simple non-invasive solution which allows users to determine the AGE level within 12 seconds. The information from the AGE Reader can assist physicians in focusing treatment on patients with the highest risk of complications. This includes patients suffering from diabetes mellitus, renal failure but also acute disorders like acute coronary syndromes and sepsis. Moreover it is an excellent tool for researchers in various fields.
The AGE Reader mu was developed and is being commercialized by DiagnOptics Technologies B.V, an innovative medical technology company in the Netherlands.
This user manual provides the instructions for use of the AGE Reader mu.

2 Intended use
When used as intended, the AGE Reader mu non-invasively gives an evaluation of Advanced Glycation End products (AGEs) in tissue. Clinical evidence shows that AGE levels may assist the physician in clinical practice to assess the risk of cardiovascular disease.
The AGE Reader mu is intended to be used by trained personnel to assess the level of auto fluorescence in human skin. Users are expected to be familiar with standard medical practices as required for patient monitoring. All instructions, procedures and information in this user manual and on the labelling on the device are to be regarded as the “Intended Use” and will fully inform the user about the correct and safe use and installation of the AGE Reader mu.
AGE measurements should be performed directly on intact healthy skin on the inner side of the dominant lower forearm. The skin at the measuring area should be healthy, homogeneous and free of birthmark, tattoos or excessive hair growth and without recent exposure to skin creams or any substance that may have fluorescent properties. Self-tanning agents should not be used for at least 2 days before measurement. Sun-blockers and other skin care products should be removed before measurement.
Pigmented skin The device and its software have been validated in patients with skin reflection >8% (Fitzpatrick class 1-4). If the UV reflectance is below 10%, the AGE Reader mu will give a warning that the signal is too low for valid results.
Radiation safety Using the guidelines of NEN-IEC 62471, it is concluded that AGE Reader mu measurements, as intended, remain considerably below the maximum radiation exposure levels for skin and for the eye of both the operator and patient.
2.1 Conditions for which the device is not to be used
This device is not intended to be used on patients where the skin at the measuring area is:
• not healthy
• not homogeneous
• damaged or tattooed
• exposed to skin care creams or any other substance that may have fluorescent properties
The measurement result can be influenced if situations mentioned above are present.

3 Warnings and precautions
The following warnings and precaution are essential for correct and safe functioning of the AGE Reader mu as is intended by the manufacturer.
The AGE Reader mu is intended for static use! It is not intended to be a portable device. Transportation must be done with great care at own risk.
Protect against falls and mechanical shocks. Do not use the device if there is visible damage and/or sharp edges.
This device emits UV-A radiation.
Measurements should be done on the inner side of the lower forearm on healthy undamaged skin without birthmarks or excessive hair growth. Self-tanning agents should not be used for at least 2 days before measuremen t. Sun-blockers and other skin car e products should be removed before measurement.
Only use the accompanying external power supply (part.nr.: CFR51000 or CFR52000).
The mains plug of the power supply is the separator that connects or disconnects the AGE Reader mu and its power supply from the mains. Avoid positioning the equipment such that access to the coupler, plug, etc. is limited (so that disconnection becomes difficult).
Do not use excessive force or sharp objects on the touchscreen.
To avoid risk of electric shock, this equipment must only be connected to a supply mains with protective earth.
Always make sure that with the use of a computer or laptop approved for medical use, the system complies with IEC 60601-1-1 for medical systems. The USB-port should be a limited circuit with a maximum current of 8A.
This device meets all requirements for electromagnetic compatibility of IEC 60601-1-2. If the user however notes unusual device behaviour, particularity if such behaviour is intermittent and associated with nearby usage of portable and mobile RF communications equipment, this could be an indication of electromagnetic interference. If such behaviour occurs, the user should try moving the interfering equipment further from this device. Failure to do so could result in the equipment not functioning properly.
The use of accessories, transducers and cables other than those specified, with the exception of replacements parts sold by DiagnOptics, may result in increased emissions or decreased immunity of the AGE Reader mu.
The AGE Reader mu should not be used adjacent to or stacked with other equipment and that if adjacent or stacked use is necessary, the AGE Reader mu should be observed to verify normal operation in the configuration in which it will be used.
The measurement window should always be kept clean.
Never place anything else than intended on top of the device.
Maintenance and repairs should only be done by DiagnOptics or authorized representatives.
Correct positioning of the arm over the window is essential and the arm should be maintained steady during the measurement process.

4 Description of the AGE Reader mu
The AGE Reader mu is a proprietary device to assist a physician in assessing cardiovascular risk. This way of non-invasive monitoring uses auto fluorescence excited by ultraviolet A light in human tissue.
The AGE Reader mu consists of a small enclosure (considered as applied part) and its detachable silicone mat for the patient to rest his arm on during the measurement. The AGE Reader mu is operated from a touchscreen with LED backlight, and controlled by an internal micro controller running dedicated AGE Reader mu Software. This software allows the user to change his preferences and calculates the AGE Reader measurement result. Results of the measurements are presented as an absolute value numerical and can be displayed in a graph on the screen. The AGE Reader mu is powered by an accompanying medically approved external power supply connected to the mains. The AGE Reader mu can also be powered from the internal rechargeable Lithium ion battery.

6 Instructions for use
6.1 Starting the AGE Reader mu
When starting the AGE Reader mu for the first time it is recommended that you charge the internal battery completely before use. This will extend the battery life. Insert the power plug into the power inlet that is located on the rear of the AGE Reader mu, labelled as “Power Inlet” (figure 2). The blue charging LED will light up when the battery is charging, when the charging LED is off, the battery is fully charged.
Turn the AGE Reader mu on by pressing the ‘power button’ (figure 1). During the start-up phase nothing is displayed on the touchscreen and the power button will not be lit. Part of this initialization is a self-test of the AGE Reader mu’s internal light sources. Notice that some light will be emitted from the measurement window for a short period during this phase this is completely harmless.
If the start-up is unsuccessful the power button will be lit red in a blinking fashion. The blinking pattern corresponds to the error code as described in section 9.2. Upon a successful start-up the graphical display will show the AGE Reader mu screen as shown below and the power button will be lit steady green.

6.3.4 Problems during measurement
If the AGE Reader mu is not able to successfully perform the measurement it will abort the measurement and indicate the problem to the user. Three problem indications exist and will be explained subsequently:
Measurement setup error indication Low-signal error indication Internal error indication
Measurement setup error indication
If during measurement the measurement mat is not placed properly on the AGE Reader mu or if the subject’s arm doesn’t completely cover the measurement window ambient light can leak into the measurement window and interfere with the measurement. Although a proper mat and arm position is the responsibility of the user, the AGE Reader mu is capable of detecting light leakage to some extent. When the AGE Reader mu detects any light leakage the measurement will be aborted and the Measurement setup error screen will be displayed as an indication to the user (figure 14).
Figure 14. Measurement setup error indication
See section 6.3.1 for instructions and check if both mat and arm are positioned properly before retrying the measurement. Press the Confirm button to return to the Main screen from where a new measurement can be started.

Low-signal error indication
If the measured fluorescence signal from the arm is too low, the AGE Reader mu is unable to perform a reliable measurement. It will then abort the measurement and raise a low-signal error (figure 15).
Figure 15. Low-signal error indication
In general a low-signal error results from a patient’s arm skin that has too much dark pigment. This in turn might be caused e.g. by birth marks, freckles or tinted skin.
See section 6.3.1 Prepare for measurement for instructions on how to position the patient’s arm before retrying the measurement. Press the Confirm button to return to the Main screen from where a new measurement can be started. If the problem persists conclude that the patient’s arm has too much pigment, a measurement with the AGE Reader mu is not possible.

7 Background on AGE values
Age is the most important factor determining the level of Advanced Glycation End­products (AGEs) in tissue. The AGE value as measured by the AGE Reader is also correlated with age. The reference values for AGE values have been based on 456 measurements in Caucasian subjects without cardiovascular disease (smokers and non-smokers) [Lutgers et al., Diabetes Care 2006, and Koetsier et al, Diabetes Technology & Therapeutics, 2010; 12(5):399-403]. Table 2 shows the mean values of the AGE value for several age decades. AGE values are given in arbitrary units ± 1 standard deviation. N represents the number of subjects in the respective age groups.

Graph 1 shows the mean AGE values as a function of age, together with the lines representing mean +/- 1 standard deviation. The coloured areas indicate the risk classes corresponding to the AGE value combined with age value.
No reliable AGE values can be given with the current AGE Reader mu software if the measured UV reflectance is below 10%. In that case no AGE value is given and the screen shows a message that a reliable measurement is not possible.
Cardiovascular risk interpretation for type 2 diabetes patients based on the AGE Reader measurement.
The AGE Reader measurement result increases considerably with age, both in healthy persons and in those with diabetes or renal disease. Calendar age is in fact the strongest determinant of the AGE Reader measurement. Keep in mind that calendar age itself is also by far the strongest risk indicator in terms of cardiovascular risk (CV risk), as is evident from all known risk scores. Thus, a healthy elderly person may have a higher measurement result than a much younger patient with diabetes. Therefore, age-dependent AGE Reader measurements within levels up to 1 standard deviation (1SD) above the age-corrected mean may serve as reference values for a certain age, but can be considered normal only for the corresponding age group. AGE Reader measurements should be considered as complementary to, and not a replacement for assessment of conventional cardiovascular risk factors and risk scores. When other risk factors such as blood pressure or cholesterol levels are clearly increased, a low AGE Reader measurement is not a reason to withhold treatment. This especially holds for younger people with extreme values of conventional risk factors. Always keep in mind that in case of markedly abnormal AGE Reader measurements (high or low) one should make sure that the measurement has been properly performed and that the measured person has not used skin creams, sun blockers or tanning agents.
Normal Group: No increased CV risk If the AGE Reader measurement is below or equal to the age-related mean, the subject has no calendar age-corrected increase in cardiovascular risk. However if the subject is an elderly person and the result is above 2.5 (even though it is at the age-related mean), the subject may still have increased cardiovascular risk due to his/her calendar age.
Risk Group I: Limited increase of CV risk
If the AGE Reader measurement is above the average but within 1SD of the age­related mean, the subject has a limited increase, corrected for calendar age, in cardiovascular risk.
Page 12
AGE Reader mu Background on User Manual AGE values
21
Risk Group II: Increased CV risk If the measurement result is above 1SD of the age related mean, the subject has an increased cardiovascular risk. In such case, the advice is to check the levels of other cardiovascular risk factors such as blood pressure and lipid levels. Depending on overall CV risk, lifestyle or even pharmaceutical treatment should be considered.
Risk Group III: Definite CV risk
If the AGE Reader measurement result is 2.9 or above, the subject has a definitely high cardiovascular risk. It is recommended that other cardiovascular risk factors should be assessed and treated, with low threshold and target values for starting or intensifying treatment.
Used in combination with conventional risk scores (UKPDS, SCORE) the following advice applies:
Normal Group: no risk reclassification to be considered Risk Group I: no risk reclassification to be considered Risk Group II: consider reclassification to a higher cardiovascular risk class Risk Group III: classification as high or very high cardiovascular risk class

8 Cleaning & maintenance
8.1 Cleaning instructions
Measurement window.
The measurement window should always be kept clean! In the design of the AGE Reader mu, special attention was given to allow cleaning the window by using a removable mat. Place the housing on a horizontal stable surface and carefully remove the mat in order to clean the measurement window. Clean the window with a slightly moistened soft non­fluorescent cleaning wipe (for example the soft reusable cleaning wipes used for spectacles) using a standard 70% alcohol solution. Avoid scratching the window and take care that no textile or paper fibres remain on the window, textiles and paper show fluorescence and may affect the measurement! After cleaning the window, replace the silicone mat in the proper position.
Silicone mat.
The silicone mat can be cleaned with standard mild cleaning agents by removing the silicone mat. If desired, the mat can be disinfected with alcohol or chlorohexidine.
Housing & touchscreen.
The housing and touchscreen can be cleaned with standard mild cleaning agents, for example a slightly moistened cloth. Make sure no fluids enter the housing at the connector inlets and no fluid collects at the bottom of the touchscreen.
8.2 Maintenance instructions
This system does not contain parts that can be serviced by the user! The internal battery can only be serviced by DiagnOptics personnel with use of an tool. The AGE Reader mu is a medical instrument that has been carefully calibrated before use. Small differences exist in the characteristics of the internal optics and the LED spectrum. Albeit small these differences may affect the measurement results of the AGE Reader mu and may impede comparisons of results between individual instruments. Unique calibration files of each individual system are used in the AGE Reader mu Software.
Never make changes in the system on your own!
If damage occurs only to the silicone mat, the power supply or the mains connector set, a replacement can be ordered, see chapter 12.

9 Problems & solutions
9.1 Power supply problems
The AGE Reader mu is either powered by its internal battery or by the supplied external 9-12VDC power supply (part. nr. CFR51000 or CFR52000). When the battery voltage drops below a workable level the AGE Reader mu will automatically be powered down. In this case apply the supplied external 9-12VDC power supply, after which the AGE Reader mu will immediately be functional again.
If the AGE Reader mu cannot be turned on while the external 9-12VDC power supply is applied, it is recommended to contact your local distributor or DiagnOptics Technologies B.V. support.
9.2 Problems during operation
When the AGE Reader mu is turned on, the software will initialize the system. If a fault condition occurs in this start-up phase a fault code is presented by red blinking of the power button with a pattern, see below. If the system successfully passes the start-up phase it enters the operational phase which is reflected by lighting the power-button green continuously.
If a fault condition occurs during the operational phase the AGE Reader mu can no longer guarantee a reliable measurement. Upon a fault the AGE Reader mu will shut-down and the power button will blink red with a pattern that reflects the fault code.
Fault codes can be recognized by the blinking pattern of the power-button. The blinking pattern is repeated continuously with a few seconds pause. The pattern itself consists of long and short blink periods (Represented as L and S respectively in the blink pattern example below). It is recommended to write down the blink pattern and contact your local distributor or DiagnOptics Technologies B.V. support. Please keep the AGE Reader mu serial number in range if you contact DiagnOptics.
Example error pattern:
Blink pattern: ____ __ __ __ __ ____
