Apolipoprotein B, Plasma
Method Description Describes how the test is performed and provides a method-specific reference
Antibody to human Apo B is added to a diluted aliquot of plasma or serum. The increase in light scatter resulting from the antigen-antibody reaction is measured and is a function of the concentration of Apo B. A multi-point standard curve is used for calculation of Apo B concentrations from the light scattering values.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
