Check that the blood is sufficiently coagulated prior to serum separation. Remove the •
suspended fibrin before placing serum on the system.
If any suspended matter is recognized in the urine to be dispensed, perform centrifugal •
separation to precipitate the suspended matter before testing the urine specimen.
If a sample requires pretreatment depending on the analysis test, consult the reagent •
manufacturer or distributor. For information about which serum separating medium is
appropriate for the sample, consult the reagent manufacturer.
A minimum quantity of sample is required for analysis. Set up an appropriate quantity of •
sample for correct sampling in the system, according to this manual.
To prevent sample evaporation, do not leave samples unsealed for an extended period of •
time. If samples evaporate, correct analysis cannot be obtained.
Handling reagents, reference materials, and control serums
To analyze serum, urine, or other samples using this system, the appropriate reagent, •
reference material, and control serum are required. For information about which products
to use, consult the reagent manufacturer, the distributor, or Beckman Coulter Technical
Services.
For reagent reference material, or control serum storage and handling, use the instructions •
of the reagent manufacturer or distributor.
The methods used to store the reagents, reference materials, and control serums are •
described in each package insert. Observe the instructions. If reagents, reference
materials, and control serums are stored improperly, results will be inaccurate even
if they are used within effective periods. Also, top system performance may not be
obtained.
Consult the corresponding reagent manufacturer or distributor for the stability of the •
unsealed product.
To place the reagent, etc., on the system, follow the instructions in this manual and •
those from the reagent manufacturer or distributor. Unless the reagent is placed properly,
accurate analysis results cannot be obtained and damage to the system could occur.
After replacing the reagent, follow the instructions on the package insert. •
Reagent interference between analysis tests
If a reagent is contaminated with another reagent during analysis, results may be affected.
The actual degree of interference differs depending on the reagent. For detailed information,
contact the reagent manufacturer or distributor. For information on how to check for cross-
contamination between tests, contact Beckman Coulter Technical Services.
Analysis performance
A high ratio of the following may affect the analysis result: hemolysis, turbidity, or
bilirubin, the drug used or its metabolite. For detailed information, contact the reagent
manufacturer or distributor. Also consult the reagent manufacturer or distributor for detailed
information about the analysis performance of each reagent.
