Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
Pediatric Minimum Volume (no repeat) |
|---|---|---|---|---|---|---|
| No | Plasma or Serum | Lithium-heparin Plasma Separator Tube (PST), Serum Separator Tube (SST) | Sodium-heparin Green Top Tube (GTT), Red Top Tube (RTT) | 0.5 mL | 0.4 mL | 0.3 mL |
Collection/Processing Instructions
Serum or plasma collected on gel separator is acceptable for up to 48 hours.
For plasma samples only:
- Sites with centrifuges capable of reaching a speed of 4,400g can centrifuge the collection tube for 3 minutes.
- Sites with standard centrifugation must centrifuge the collection tube for 10 minutes at 1900g.
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Serum/Plasma | Ambient | 8 hours |
| Refrigerated | 5 days | |
| Frozen | >5 days |
Interferences
Human Anti-Murine Antibodies (HAMA) may develop leading to test interference in patients receiving murine-based agents for chemotherapy or tumor-imaging studies. Fluorescein will interfere; specimens should not be drawn for 48 hours following fluorescein angiography for diabetic retinopathy.
For testing performed at Weston: High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay. It is recommended that patients refrain from consuming any multivitamin or supplement containing biotin for at least 72 hours prior to collection of a blood sample.
Interpretations
This is a qualitative test. Negative qualitative results that are inconsistent with the clinical evidence should either be repeated in 48-72 hours or confirmed by a quantitative method. The reference value for a positive pregnancy test is 15 mIU/mL. hCG is detected as early as one week after conception with average values of 50 mIU/mL (Clinical Chemistry 43:12;2233-2243 (1997)).
