Clinical Significance
Obstetric Panel - This panel includes tests used for routine prenatal care during early pregnancy, which have been recommended for all women during early pregnancy by the American College of Obstetricians and Gynecologists (ACOG) [1]. An alternative panel, the Obstetric Panel with Fourth Generation HIV (test code 93802), is available and may be ordered to simultaneously screen for HIV infection.
Additional tests typically done in early pregnancy (but not included in this panel) include urinalysis, tests for sexually transmitted infections and tuberculosis, and blood glucose testing for women at high risk ...

If Antibody Screen is positive, then Antibody Identification, Titer, and Antigen Typing will be performed at an additional charge (CPT code(s): 86870, 86886, 86905).
If RPR screen is Reactive, then RPR Titer and Chemiluminescence - Treponemal Antibody Immunoassay for Confirmatory testing will be performed at an additional charge (CPT Code(s): 86593, 86780).

Preferred Specimen(s)
Whole blood full EDTA (lavender-top) tube and
Whole blood full ACD-A or ACD-B (yellow-top) tube and
6 mL serum
Collection Instructions
EDTA (lavender-top): Maintain specimen at room temperature. Do not refrigerate. Collect EDTA (lavender-top) tube last. Traumatic draw can introduce thromboplastin and trap WBC and platelets. Refrigeration can precipitate fibrin and trap WBC and platelets.
Dietary supplements containing biotin may interfere in assays and may skew analyte results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
