Immunoglobulins IgG, IgA and IgM
14 - 21 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
0.5 mL (Note: This volume does not allow for repeat testing.)
Separate serum from cells within one hour of collection. Transfer to a plastic transport tube before shipping. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Refrigerate or freeze.
Grossly hemolyzed; bacterial contamination; lipemic specimen; icteric specimen; non-serum specimen types
Quantitation of immunoglobulins (lgG, IgA, and IgM) in serum provides useful information for the evaluation of certain disease states. Increased concentrations of these proteins may occur in disorders such as monoclonal or polyclonal gammopathies. Differentiation of these gammopathies can be supported by measuring selective increases in immunoglobulins. Decreased concentrations of immunoglobulins may indicate hypogammaglobulinemia as a result of primary or secondary immunodeficiency.
