INTENDED USE
For the quantitative determination of human IgA in serum by imunoturbidimetric assay.   Measurement of IgA aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.
FOR IN VITRO DIAGNOSTIC USE.

REAGENT PREPARATION
The reagents are ready to use and do not require reconstitution.

STORAGE AND HANDLING
All reagents should be stored refrigerated (2-8°C).  Return all reagents to 2-8°C promptly after use.  Unopened reagents can be used for one year from the date of manufacture, as indicated by the expiration date on the package and bottle labels.  Opened reagents can be used for one month if stored at 2-8°C.

Accuracy / Correlation
A comparison of the K-ASSAY ®   IgA assay and an INCSTAR IgA Test Kit was performed on a Hitachi 704 automated analyzer and a COBAS Mira.  The test results provided the following data:

y = 1.0188x - 6.73
r = 0.9899
n = 45
x = INCSTAR IgA Test Kit
y = K-ASSAY ®   IgA assay

x min = 39 y min = 48
  max = 780   max = 769
  mean = 243   mean = 241
