MHA-TP, Serum (View in report form.)

CERNER / EPIC MNEMONIC:

MHA-TP

CPT CODE: 86781
DAYS PERFORMED:

Monday, first shift

TURNAROUND TIME:

1 week

CONTAINER TYPE:

Red top Vacutainer® tube or SST tube

SPECIMEN REQUIREMENTS: Blood (serum)
REJECTION CRITERIA: Excessive hemolysis, gross contamination of specimen, chylous serum, improper storage of specimen, inappropriate specimen container, insufficient specimen volume.
MINIMUM VOLUME: 1 mL blood (0.2 mL serum)
REFERENCE RANGE: Nonreactive
LIMITATIONS OF TEST: The assay may fail to detect antibodies in approximately 30% of patients with early primary syphilis and in 5% of sera from patients with late syphilis.
METHODOLOGY:

Gelatin particle agglutination

ADDITIONAL INFORMATION: The assay, which confirms the presence of antibodies to the pathogenic strain of Treponema pallidum, is used to diagnose syphilis. It is NOT recommended as a screening test for syphilis. The assay should NOT be used to follow treatment or establish reinfection since treponemal antibody tests can remain reactive for the life of treated patients. Patients from whom reactive results are obtained are reported to the City of Chicago Board of Health. This is mandated by law.
TEST SYNONYM(S):HATTS.; TPHA; Treponemal Antibody Test; MHA-TP
