CPT Code(s):
82679
Specimen Requirements:
Type: Serum
Note: No isotopes should be administered to the patient within 24 hours prior to the venipuncture.
Container/Tube: Red-top tube, gel-barrier tube or lavender-top tube (EDTA)
- If a red-top tube or lavender-top tube is used, transfer the separated serum to a plastic transport tube.
Sample Volume: 0.8 mL
Minimum Volume: 0.4 mL (Repeat testing is not possible with this specimen volume.)
Storage: Refrigerate specimens after collection.
Stability (collection to time of analysis/testing):
- Ambient: 3 days
- Refrigerated: 7 days
- Frozen: 14 days
- Freeze/Thaw cycles: Stable (x3)
Rejection Criteria:
- Gross hemolysis
- Recently administered radioisotopes
- Lipemia
- Icteric specimen
Use:
This test is used to evaluate postmenopausal vaginal bleeding due to peripheral conversion of androgenic steroids. Increased estrone levels may be associated with increased levels of circulating androgens and their subsequent peripheral conversion.
Methodology:
Radioimmunoassay (RIA)
