INTENDED USE
For the quantitative determination of human complement C4 (4th complement component) in serum by immunoturbidimetric assay.  Complement is a group of serum proteins that destroy infectious agents.  Measurement of these proteins aids in the diagnosis of immunological disorders, especially those associated with deficiencies of complement components.
FOR IN VITRO DIAGNOSTIC USE.

REAGENT PREPARATION
The reagents are ready to use.  They do not need to be reconstituted.

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 precision for the K-ASSAY ®   Complement C4 assay was determined using packaged reagents, pooled human serum, and a Hitachi 717 analyzer.

Precision - Within Run
Sample I Sample II Sample III
N = 20 N = 20 N = 20
Mean = 5.7 Mean = 36.3 Mean = 58.6
S.D. = 0.29 S.D. = 0.76 S.D. = 1.98
C.V. = 5.17% C.V. = 2.1% C.V. = 3.38%

Precision - Between Runs
Sample I Sample II Sample III
N = 10 N = 10 N = 10
Mean = 6.51 Mean = 30.6 Mean = 53.2
S.D. = 0.24 S.D. = 1.18 S.D. = 1.12
C.V. = 3.72% C.V. = 3.87% C.V. = 2.1%

Accuracy / Correlation
A comparison of the K-ASSAY ®   Complement C4 assay and an INCSTAR Complement C4 Test Kit was performed using a Hitachi 717.  The test results provided the following data:

y = 0.739x + 2.46
r = 0.988
n = 60
x = INCSTAR Complement C4 Test Kit
y = K-ASSAY ®   Complement C4 assay

x min = 11 y min = 9
  max = 56   max = 45
  mean = 31   mean = 25
