Precision
Intra-assay Precision (Precision within an assay):Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Intra-Assay CV: ≤6.8%
Inter-assay Precision (Precision between assays):Three samples of known concentration were tested in five separate assays to assess inter-assay precision.
Inter-Assay CV: ≤9.4%
Recovery
Recovery was determined by spiking various levels of Immunoglobulin M into serum and plasma.

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Immunoglobulin M and their serial dilutions.
The results were demonstrated by the percentage of calculated concentration to the expected.

General Annotation
Sub Unit:
N/A
Function:
Due to its polymeric nature, IgM possesses high avidity, and is particularly effective at complement activation. By itself, IgM is an ineffective opsonin; however it contributes greatly to opsonization by activating complement and causing C3b to bind to the antigen.
Location:
Immunoglobulin M, or IgM for short, is a basic antibody that is produced by B cells. IgM is by far the physically largest antibody in the human circulatory system. It is the first antibody to appear in response to initial exposure to antigen.
