4 - 10 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
For more information, please view the literature below.
1.5 mL (Note: This volume does not allow for repeat testing.)
Gel-barrier tube or red-top tube
Transfer specimen to a plastic transport tube before freezing. Serum must be separated from cells within one hour of venipuncture. Submit serum in a plastic transport tube.
Freeze. Stable at room temperature for three days or refrigerated for 14 days. Stable when frozen for 3.79 years. Freeze/thaw cycles: stable x2.
Plasma specimen received; gross hemolysis
Comprehensive thyroglobulin can be used to monitor recurrence of thyroid cancer. All specimens are tested for the presence of antithyroglobulin autoantibodies (anti-Tg). Specimens negative for the presence of anti-Tg are reflexed to thyroglobulin testing by ICMA, and specimens positive for the presence of anti-Tg are reflexed to thyroglobulin testing by RIA.
Specimens submitted for comprehensive thyroglobulin testing are stored frozen for one year to allow for future testing.
Immunochemiluminometric (ICMA) or double antibody radioimmunoassay (RIA) when anti-Tg autoantibodies are present
