Thyroid Panel with TSH
A classic thyroid panel plus TSH — the most sensitive first-line thyroid marker. One draw, results usually in 1–2 business days.
This panel pairs the classic thyroid measures — T4, T3 uptake, and the free thyroxine index — with TSH, the pituitary hormone that's the most sensitive early signal of thyroid trouble. Together they give a broad, first-line assessment of thyroid function in one draw.

Understanding Your Results
Results post to your secure online account usually in 1–2 business days, each value with its range. TSH and T4 together do most of the interpretive work: a high TSH with low T4 suggests an underactive thyroid, while a low TSH with high T4 suggests an overactive one.
