Thyroglobulin determinations have been widely used to complement other procedures as an aid in identifying the presence or absence of functioning thyroid tissue. Useful in the differential diagnosis of congenital hypothyroidism and the management of nonmedullary differentiated thyroid carcinoma.

Patient Preparation:
Specimen collection after fluorescein dye angiography should be
delayed for at least 3 days. For patients on hemodialysis, specimen
collection should be delayed for 2 weeks. According to the assay
manufacturer Siemens: "Samples containing fluorescein can produce
falsely depressed values when tested with ADVIA Centaur TSH3 Ultra
assay."

Notes
Transport Temperature: Room Temperature Reject Criteria: Plasma According to the assay manufacturer Siemens: "In general, the fluorescein clearance (requires) about 48 to 72 hours." For patients in "end stage renal disease on hemodialysis, the elimination will be delayed likely by several cycles of hemodialysis. Assuming the dialysis cycle serves as one half-life (and) using the rule of thumb that 5 half-lives are required to completely eliminate a compound, two weeks is conservative (if) dialysis is performed 3 times per week."
