INTENDED USE
For the quantitative determination of human albumin in urine by immunoturbidimetric assay.  Measurement of albumin in urine aids in the diagnosis of kidney dysfunction.
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.

PERFORMANCE
Precision
The within-run, between-run, and total precision for the K-ASSAY ®   Microalbumin assay was determined using packaged reagents, human urine samples, and a Roche / Hitachi 917 analyzer in accordance with CLSI EP5-A2.

Accuracy / Correlation
Testing was performed on a Roche / Hitachi 917 analyzer using unaltered, natural human urine samples and in accordance with the CLSI EP9-A2 guideline.  A comparison of the K-ASSAY ®   Microalbumin and the Roche Tina-Quant Albumin assay was performed with the following results:

Linear Regression: y = 0.9155x + 0.0084
r = 0.9964
n = 93
x = Roche Tina-Quant Albumin
y = K-ASSAY ®   Microalbumin

x min = 0.33 mg/dL y min = 0.14 mg/dL
  max = 33.04 mg/dL   max = 30.24 mg/dL
  mean = 6.778 mg/dL   mean = 6.213 mg/dL
