INTENDED USE
For the quantitative determination of human insulin in serum and plasma 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 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 ®   Insulin assay was determined using packaged reagents, human serum samples, and a Roche / Hitachi 917 analyzer.

Precision - Within Run
Sample I Sample II Sample III
N = 10 N = 10 N = 10
Mean = 18.81 Mean = 27.82 Mean = 73.17
S.D. = 0.224 S.D. = 0.192 S.D. = 0.760
C.V. = 1.19% C.V. = 0.69% C.V. = 1.04%

Precision - Between Runs
Sample I Sample II Sample III
N = 10 N = 10 N = 10
Mean = 12.21 Mean = 25.9 Mean = 68.74
S.D. = 0.530 S.D. = 0.777 S.D. = 1.693
C.V. = 4.34% C.V. = 3.00% C.V. = 2.46%

Accuracy / Correlation
A comparison of the K-ASSAY ®   Insulin assay and another company's Insulin EIA was performed with the following results:

Serum Samples: y = 0.8061x + 2.8674
r = 0.997
n = 32
x = another company's Insulin assay
y = K-ASSAY ®   Insulin Assay

Plasma Samples: y = 0.8161x + 4.5552
r = 0.986
n = 47
x = another company's Insulin assay
y = K-ASSAY ®   Insulin Assay

Assay Range
1 - 100 µIU/mL
