|
What are precipitation tests?
|
Some tests detect a specific antibodyor antigen in the patients serum by precipitating it in the lab with corresponding antigen or antibody either in a test tube or in agar diffusion.
|
|
|
How may precipitation tests be facilitated?
|
This is done by first separating the proteins in the patients serum by electrophoresis.
The electrophoresis in itself may provide useful information about antibodies. |
|
|
Most immunoglobulins fall in the gamma globulin zone. TRUE/FALSE
|
TRUE. A sharp spike in the gamma globulin area on electrophoresis suggests the overproduction of a single antibody, as might occur in a tumor of a single clone of plasma cells.

|
|
What is immunophelometry?
|
It is a technique that quantitates the amount of antigen antibody complex in solution through measuring the light scattering characteristics of the complexes.
|
|
|
When is immunophelometry employed?
|
It is used to test for C reactive protein(CRP) which rises in the acute phase of inflammation and malignancies.
