Test Code

CPT Code is subject to a Medicare Limited Coverage Policy and may require a signed ABN when ordering.

Clinical Significance

T 3 Uptake - T3 Uptake (T3U) is used with measurement of Thyroxine (T4) to calculate the Free T4 Index. The calculated Free T4 is useful in the assessment of thyroid diseases. Elevations are associated with Hyperthyroidism or Thyroid Hormone Resistance whereas low concentrations are associated with Hypothyroidism.

Clinical Significance

T 3 Uptake - Decreased: Pregnancy, estrogens, hyperproteinemia, acute intermittent porphyria. Increased: Androgens, hyperproteinemia, stress, acute liver disease. This assay is a measure of available thyroid hormone binding sites and should be interpreted with thyroxine levels.

Special Instructions

This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation.

Expected Turnaround Time

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.

Container

Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube. Do not use oxalate, EDTA, or citrate plasma.

Collection

If a red-top tube or plasma is used, transfer separated serum or plasma to a plastic transport tube.

Limitations

T 3 is decreased with nonthyroidal chronic diseases and influenced by the state of nutrition. It is not helpful for evaluation of hypothyroidism. It may be normal with thyrotoxicosis (thyroxine thyrotoxicosis). 4

Additional Information

Increased T 3 often occurs in hyperthyroidism, but in approximately 5% of cases only T 3 is elevated, “T 3 toxicosis.” Do not confuse T 3 with T 3 uptake; these are two different tests. The latter is done very commonly as part of the usual thyroid profile. Less than 1% of T 3 is unbound.
