INTENDED USE
For the quantitative determination of human Beta-2 Microglobulin in
serum / plasma or urine by immunoturbidimetric assay.
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 until the expiration date on the package and bottle labels.  Opened reagents can be used for 1 month if stored at 2-8°C.  

PERFORMANCE
Precision
When a sample containing a known level of β2MG is tested 10 times, the CV of the test should typically be under 7%.

Accuracy / Correlation
A comparison of the K-ASSAY ®   Beta-1 Microglobulin assay and the latex agglutination method of another company provided the following data:

Serum (mg/L):
y = 0.985x + 0.235
r = 0.999
n = 65
x = Company A's latex assay
y = K-ASSAY ®   Beta-2 Microglobulin assay

Urine (µg/L):
y = 0.960x + 6.177
r = 1.000
n = 50
x = Company A's latex assay
y = K-ASSAY ®   Beta-2 Microglobulin assay


Assay Range
Serum and Plasma:   0.2 - 80.0 mg/L
Urine:   30 - 8,000 µg/L   (or 0.03 - 8.00 mg/L)

INTERFERENCE
Bilirubin C :     No interference up to 30 mg/dL
