PTS PANELS™HDL Cholesterol Test Strips
for use with CardioChek®Brand Analyzers
I
NTENDED USE
PTS PANELS HDL Cholesterol Test Strips provide a quanti tative measurement of High Density Lipoprotein (HDL) Cholesterol. This system is intended to assist in screening for decreased HDL Cholesterol, a risk factor in coronary heart disease, and is intended for in-home (self-testing) or professional use.
SUMMARY
HDL Cholesterol, often referred to as “good cholesterol”, is an important component of a lipid profile. A low HDL indicates increased risk of coronary heart disease, while a high HDL indicates decreased risk. Individuals should consult their healthcare professional with any questions about HDL levels and when to use this test. A MEMo Chip inserted into the analyzer before any test can be run. The MEMo Chip contains test name, calibration curve, lot number and test strip expiration date. After the test strip is inserted into the analyzer and blood applied to the strip, test results are displayed in about a minute.
PRINCIPLE OF THE TEST
HDL Cholesterol test results are based on a reading of light reflected off a test strip that has changed color after blood is applied. The deeper the color is, the higher the HDL level. The analyzer converts this reading into an HDL result and displays it. This procedure is based on the “Trinder Method” for the determination of cholesterol.

• Store test strip package in a cool, dry place at room temperature of 68-86°F (20-30°C). Strips may be stored in a refrigerator at 35-46°F (2-8°C), but must be brought to room temperature before using. Do not freeze.
• Keep away from heat and direct sunlight.
• Do not remove or discard the desiccant packet in the vial.
• Always replace vial cap immediately after removing a test strip.
• Use test strip as soon as you have removed it from the vial.
• Keep the MEMo Chip either in the analyzer or stored with the original lot of strips.
• Store the test strips in the original vial. Do not combine with other strips and do not MEMo Chip in the test strip vial.
• After opening, the test strips are stable until expiration date if vial is properly stored and always capped.
PRECAUTIONS
• For in vitro diagnostic use. Intended for self-testing.
• PTS PANELS Test Strips can only be used in the CardioChek brand analyzer.
• Make sure the MEMo Chip and test strip lot numbers match. Never use a MEMo Chip from a different lot than the test strip.
• Out-of-date or expired strips cannot be used in your test system. Check vial for expiration date.
• Add all of the blood to the test strip at once. If you do not get all of the blood on the strip, do not add blood to the same strip. Test again with a new unused test strip and fresh blood sample.
• Discard test strip after using. Strips are to be read once. Never
• Do not ingest.
SPECIMEN COLLECTION AND PREPARATION
PTS PANELS Test Strips are designed for use with fresh capillary (fingerstick) whole blood. Fresh venous whole blood collected in EDTA or heparin tubes is also an acceptable sample. To obtain a drop of blood from a fingerstick, follow the steps listed below:
• Use of lotions and handcreams should be avoided before testing.
• Hands should be washed in warm water with antibacterial soap, rinsed and dried thoroughly.
• If you wipe the fingertip with alcohol, be sure that the alcohol dries completely before sticking the finger.
• Use a sterile, disposable lancet to puncture the side of the fingertip.

• Wipe away the first drop of blood with a clean piece of gauze.
• Gently, without force, apply pressure to the fingertip to accumulate a drop of blood.
• Excessive squeezing of the finger may alter test results.
• See the “TESTING” section for information on how to apply the blood to the test strip.
• Discard used materials properly.
Caution: Handle and dispose of all materials coming in contact with blood according to universal precautions and guidelines.
TESTING IMPORTANT: Read all instructions carefully before testing.
1. Insert the MEMo Chip that matches the lot number on the test strip vial and press one of the buttons to turn the analyzer ON.
2. Hold the test strip by the end with the horizontal raised lines. Insert the opposite end of the strip into analyzer. Push the strip in as far as it will go.
Ribs that guide the strip into the analyzer
Blood application window
Hold strip by this end.
3. When APPLY SAMPLE appears on the display, use a capillary blood collector or pipet to apply 15 µL of whole blood to the test strip blood application window.
4. In about a minute, the result will appear on the display. Remove and discard strip. DO NOT
add more blood to a
test strip that has been used.
ADDITIONAL CONSIDERATIONS
1. If no result is displayed, make sure: – Enough blood was added to the test strip to completely fill the blood application window. – Analyzer is ON. (If it won’t turn ON, refer to analyzer User Guide section on changing
batteries.)
– MEMo Chip is properly installed in port.
2. If you get a reading of, “<___”, “ >___” or any unexpected result, test again.
3. See analyzer User Guide Troubleshooting section for additional help.
4. To verify enough blood has been applied to the test strip, remove strip after testing and check back side of reac tion area. Reaction area should be completely and evenly colored. If the area is not completely and evenly colored, discard the used test strip and test again.

TEST RESULTS
Results are displayed in either milligrams per deciliter (mg/dL) or in milli moles per liter (mmol/L). The mg/dL measurement is a US version, while mmol/L is used in many countries around the world. The analyzer is preset to US units by the manufacturer. No calculation of results is necessary. To change to INTL (mmol/L) units, please see the analyzer User Guide.
QUALITY CONTROL
Please refer to the analyzer User Guide for the proper pro cedure and materials to be used to perform Quality Control tests. Quality Control tests are used to ensure that the system (analyzer, strips, and MEMo Chip) is working properly. Users should run controls when results are questionable or to comply with their own facility’s quality control requirements.
EXPECTED VALUES
Blood cholesterol levels will vary from time to time depending on food consumed, activity levels, health status, medication dosages, stress or exercise. The expected or reference ranges recommended are from the US National Cholesterol Education Program (NCEP) 2001 Guidelines and are:
40 mg/dL and below (1.04 mmol/L) - Low (increased risk for coronary heart disease)
•
9
• 60 mg/dL and above (1.55 mmol/L and above) - High (decreased risk of coronary heart disease) A healthcare professional will discuss values that are specifically appropriate for each patient. ALWAYS CONSULT A HEALTHCARE PROFESSIONAL BEFORE MAKING ANY CHANGES IN TREATMENT PLANS OR MEDICATION.
MEASURING RANGE
The HDL cholesterol test system will detect HDL levels from 25-85 mg/dL (0.65-2.20 mmol/L) and will display a number value for results in this range. If the display reads “<___” (less than measuring range), the HDL cholesterol level is below 25 mg/dL (0.65 mmol/L). Results above 85 mg/dL (2.20 mmol/L) will read “ >___” (greater than measuring range). If a “ < ” or “ > ” result is displayed, always test again. At least two measurements of HDL Cholesterol on sepa rate occasions should be made before a medical decision is made, since a single reading may not be representative of a patient’s usual HDL Cholesterol concentration. This test does not replace a lipid panel run by a laboratory. Never make any medical decisions based on your results. Always contact your healthcare professional for advice.
LIMITATIONS OF THE PROCEDURE
1. PRESERVATIVES: Blood samples preserved with Fluoride or Oxalate should not be used for testing with this system. EDTA and Heparin do not interfere with the test. Fresh whole blood is the specimen of choice.
2. NEONATAL USE: This product has not been tested using neonatal blood. Until testing is done this test system should not be used on neonatal blood samples.
3. METABOLITES: Reducing substances such as Vitamin C may falsely decrease the test result.
4. Bilirubin up to 10 mg/dL and hemoglobin up to 750 mg/dL do not interfere. Triglycerides up to 1000 mg/dL do not interfere.
5. HEMATOCRIT: Hematocrit values above 49% may incorrectly lower the test result and below 33% may incorrectly increase the test result.
6. DRUGS: Both dopamine and α-methyldopa interfered at all levels tested starting at levels of
1.75 mg/dL for dopamine and 0.625 mg/dL for α-methyldopa.
PERFORMANCE CHARACTERISTICS
1. ACCURACY: In a two-site clinical study, correlation was established between a new modified test strip and a previous formulation of the test strip. HDL cholesterol of forty (40) subjects was measured on both the new and the previous test strip formulation. The results for the comparison follow. PTS PANELS HDL Cholesterol New vs. Original Number of patients = 40 Range of patient results: 29 to 83 mg/dL slope = 0.835 y-intercept = 5.6 r = 0.96 Bias at 40 mg/dL = -1.0 mg/dL
The following three studies were performed using the original test strip formulation to which the new test strip was compared above.
A professional clinical study was performed at three sites. HDL cholesterol levels were measured on fresh capillary blood specimens from 88 persons by healthcare professionals. The HDL Cholesterol Test Strips were compared to results from an automated HDL method. PTS PANELS HDL Cholesterol vs. Automated Method Number of patients = 88 Range of patient results: <25 to >85 mg/dL slope = 1.1 y-intercept = -4.1 r = 0.89 Bias at 35 mg/dL = -0.2 mg/dL
In another study, the HDL Cholesterol Test Strips were run by professionals on 87 patients from four sites and results compared to those run on the same patients by the Abell-Kendall method in a Cholesterol Reference Method Laboratory Network (CRMLN) laboratory. The results were: PTS PANELS HDL Cholesterol vs. Abell-Kendall Method Range of patient results: <25 to 80 mg/dL Slope = 0.85 y-intercept = 2.2 r = 0.85 bias at 35 mg/dL = -3.1 mg/dL
In a consumer study eighty-seven (87) consumers tested their HDL cholesterol with the PTS PANELS HDL Test Strips. These consumer results were compared to a reference HDL method that is recommended by the Centers for Disease Control (CDC).
None of the consumers’ results in this study indicated their HDL cholesterol was 35 mg/dL or greater when their HDL was below 35 mg/dL by the reference method. About 28% of consumers
in this study who tested their own HDL one time obtained results less than 35 mg/dL when their HDL was 35 mg/dL or higher by the reference method. When the test was repeated, this rate improved to 16%. This means that when you test your own HDL, you may at times get results below 40 mg/dL when your results are actually above 40 mg/dL. Duplicate testing is especially important to confirm results below 40 mg/dL.
. PRECISION: A laboratory professional tested twenty replicates of three levels of whole blood for
2
HDL cholesterol. The following results were obtained: No. of Samples 20 20 20 Mean HDL Cholesterol Conc. (mg/dL) 36.4 45.5 65.0 Std. Deviation (mg/dL) 1.67 2.56 4.73 Coefficient of Variation (%) 4.59 5.63 7.28
Two lay persons tested blood at two levels of HDL cholesterol with the following results:
Lay person 1 Lay person 2 No. of Samples 20 20 20 20 Mean HDL Cholesterol Conc. (mg/dL) 45.8 69.4 45.2 64.3 Std. Deviation (mg/dL) 2.73 5.06 2.95 3.34 Coefficient of Variation (%) 5.97 7.29 6.52 5.19 This means that results should not vary more than about 8%.
