Test ID: PSPTG    
Phosphatidylserine/Prothrombin Antibody, IgG, Serum

Method Description Describes how the test is performed and provides a method-specific reference

The QUANTA Lite sPS/PT IgG assay is an enzyme-linked immunosorbent assay (ELISA). Briefly, purified antiphosphatidylserine/prothrombin (PS/PT) complex is coated onto a 96-well plate. Calibrators, controls, and diluted patient samples are added to the wells of the plate. If present, IgG antibodies to the PS/PT complex will bind during an incubation step. After a wash step, an antihuman IgG horseradish peroxidase-labelled conjugate is added. After another incubation and wash step, a peroxidase substrate solution is added, which will change color in the presence of the conjugated enzyme. Lastly, the reaction is stopped by the addition of 0.44 M sulfuric acid. The absorbance of the colored produced is proportional to the amount of IgG PSPT antibodies in the sample. Control and patient results are calculated based on a curve generated from the kit calibrators.(Packet insert: QUANTA Lite aPS/PT, IgG , Rev. 2 1/2016, INOVA diagnostics, San Diego, CA; QUANTA Lite aPS/PT, IgM ELISA kit, Rev. 4 9/2018, INOVA diagnostics, San Diego, CA)

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.

Tuesday; Evening

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

7 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

14 days

Performing Laboratory Location Indicates the location of the laboratory that performs the test
