CHAPTER 3 Theory of Operations

Principles of Methodologies

Principles of Rate Nephelometry

The rate nephelometer measures the increase in the intensity of light scattered by particles
suspended in a cuvette. The light source for the rate nephelometer is a 670 nm laser. The
detector is placed at a 90° angle from the laser beam to measure light scatter, as shown in
Figure 3.1.

Principles of Rate Turbidimetry

The rate turbidimeter measures the decrease in the intensity of light as it passes through a
solution of light scattering particles in a cuvette. The light source for the rate turbidimeter is a
light emitting diode (LED) at a wavelength of 940 nm. Turbidimetric measurements are made
at 0° from the incident beam as shown in Figure 3.1.

Antigen Excess Testing

Overview

Antigen excess (AGXS) testing is only necessary for some IMMAGE 800 protein reagents.

Immunoglobulin G (serum IGG, urine IGU), Immunoglobulin A (IGA), Immunoglobulin M
(IGM), Kappa (KAP), Lambda (LAM), Haptoglobin (HPT), Urine Transferrin (TRU),
Alpha-1-Microglobulin (A1M), Microalbumin (MA) and Albumin (ALB) which are
identified by the system as ambiguous, are tested for antigen excess condition if AGXS testing
is enabled. A reaction is ambiguous if the rate response could represent either an antigen
excess or an antibody excess reaction.

Antibody Excess

When the reaction is to the left of the optimal antibody-antigen proportions the reaction is in
antibody excess (AbXS). This indicates all the antigen in the sample is bound, forming
complexes. This is the ideal condition for the reaction to take place.

Antigen Excess

When the reaction is to the right of the optimal antigen-antibody proportions the reaction is in
antigen excess (AgXS) and the rate response will start to decrease due to excessive levels of
antigen.

When a non-standard dilution has been selected for a chemistry and sample type, whenever
this chemistry is run in this sample type, the system uses the selected non-standard default
dilution as the initial dilution. If the test is out of range at this dilution, the system will step up
or step down to a different dilution.

If the original sample was programmed to run with a standard dilution, and later you changed
the default dilution to a non-standard dilution, the sample will be rerun with the standard
dilution.

Defining an AGXS Limit

The AGXS Limit is a user-defined value. The AGXS Limit feature will only be available if the
UDR has a status of "calibrated" and uses a "Non-Competitive Nephelometric" or "Non­Competitive NIPIA" protocol. Entry of this value in the AGXS Limit field is only available
after a UDR multi-point calibration has been performed and approved.

Entering an AGXS Limit value into the UDR definition will clear the calibration program of
the defined UDR. The AGXS limit is calibration specific; therefore, recalibrating a UDR
using a multi-point calibration will clear the AGXS Limit field and disable AGXS flagging.

During the sample run, if the calibrated rate for a UDR sample reaction is equal to or greater
than the value entered for the AGXS Limit in the UDR definition, the system will suppress the
results and display ******* in the results column on the results display and printout instead of
a numerical result. AGXS flagging shall not apply during UDR Rate Mode runs.

Calibrating a UDR Chemistry

Introduction

A UDR can be calibrated by using a multi-point calibration. Subsequently, this calibration
may be updated using a single-point update calibration. The UDR chemistry calibration, using
a multi-point calibration or single-point update, requires that the protocol definition be
completed and the chemistry name configured. The calibration is programmed from the User­Defined Chemistries screen shown in Figure 5.6. The calibrators are run as routine test
samples using the defined protocol. A UDR calibration must be on a separate run from
samples for that UDR chemistry. The instrument response (IR) for each calibrator replicate is
generated.

Once the calibration is approved, the UDR cal status is in Calibrated and UDR chemistries
can be run with other Beckman Coulter chemistries. Using the UDR calibration data, the
system will calculate a final result in the concentration units selected in the protocol.

March 2004 Page 7-7

7

Entering an Off-line Dilution Factor

Introduction

An Off-line Dilution Factor may be entered for a sample through the Sample Options screen.
This factor represents a user prepared dilution of the sample. The Default Dilution normally
used in the calculation of concentration for an analyte should be considered in the creation of
a user prepared dilution.

The Off-Line Dilution Factor applies to the current sample only. When a sample using an off­line dilution factor is run, the system makes no further dilutions. It runs the sample "as is"; it
does not create the default dilution or any out-of-range dilutions. Each result is automatically
multiplied by the user-entered off-line dilution factor.

Example:

To assay an IGA sample at twice the default dilution:

• To make twice the dilution of the analyte being assayed the user must know the Default
Dilution and appropriate diluting fluid for the analyte.

• Find the Default Dilution and diluting fluid for IGA in IMMAGE Immunochemistry
Systems Chemistry Information Manual, APPENDIX B, Measuring Ranges/Dilution
Fluids.

- The Default Dilution for IGA is 1:36.

- The diluting fluid for IGA is DIL1.

• Prepare the Default Dilution for the analyte being tested.

- For IGA, make a 1:36 dilution by diluting 1 part serum in 35 parts of DIL1.

• Prepare a 1:2 dilution of the previously prepared Default Dilution.

- Dilute 1 part of Default Dilution in 1 part of DIL1.

- The final dilution factor is now 1:72.

• Enter an Off-line Dilution Factor of 72 during sample programming.

• The system will produce a final result by automatically multiplying each test result from the
sample by 72.

Alternatively the user may run an off-line dilution without selecting to use this feature. The
system will perform tests using the default dilution and out-of-range dilutions as required.
The user would then need to manually multiply all test results for the sample by the user­prepared dilution factor.

Entering Off-line Dilution Factor

Follow the steps below to enter an Off-line Dilution Factor.

Step Action

1Select Sample Options [F3] from the Program Sample screen.
2 Choose the Off-line Dilution Factor field.
3 Enter the factor by typing the number of total parts of diluent + sample

(1.01-9999.99), and press [Enter].

If a non-standard or off-line dilution is selected, a condition of antigen excess could
exist which may not be detected by the IMMAGE 800 System.

When an off-line dilution is selected, diluent incompatibility is not detected by the
IMMAGE 800 System. Only chemistries using the same diluent type should be run on
a sample with an off-line dilution preparation. Refer to the IMMAGE
Immunochemistry Systems, Chemistry Information Manual, Appendix F, System
Reagent Configuration and Part Numbers for a list of chemistries using the same
diluent type.

CAUTION

• Control results are compared to the ranges defined by the mean and standard deviation.

• Control IDs, like Sample IDs, must be unique for each sample within a run.

• Control IDs, unlike Sample IDs, can be reused after the control sample is run. When the
sample status of a Control ID is Complete or Incomplete:

- the Control ID can be selected to run again.

- the status will automatically change to Sample Required.

-any Pending tests are deleted from an Incomplete control sample program.

Exception: if controls are programmed by bar code, the system will try to run Pending tests
from an Incomplete sample.

Refer to the IMMAGE 800 Immunochemistry System Operations Manual for further details.

Bar Coded Controls

Bar code labels can be used to identify control samples. The bar code must encode a defined
Control ID.
