Platelet Antibody, Serum
Method Description Describes how the test is performed and provides a method-specific reference
Solid-phase enzyme immunoassay (SPEIA) uses purified platelet membrane glycoproteins as "targets" rather than intact platelets and this provides a simple "panel" of target antigens. These purified glycoproteins are permanently affixed to the interior of concave wells in plastic trays. The attachment of patient antibodies to these glycoproteins is detected by the addition of a second stage antihuman globulin reagent which is enzyme tagged. The addition of enzyme substrate is followed by a visible color change which permits rapid visual reading of the tray or automatable reading.

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.
Monday through Friday; 7:30 a,m.-5:00 p.m.
Saturday; 10:00 a.m.-6:00 p.m
