The classic 4-marker thyroid panel — TSH, Total T4, T3 Uptake, and calculated Free T4 Index (FTI) from one draw. The Thyroid Panel with TSH is the classic thyroid workup that Quest and Labcorp have offered for decades: TSH, Total T4 (thyroxine), T3 Uptake, and the Free T4 Index (FTI) — a value calculated from Total T4 and T3 Uptake that estimates free hormone activity. It screens for hypothyroidism and hyperthyroidism and is a good choice for tracking trends against older results from the same panel. Note: this panel estimates free hormone levels rather than measuring them directly. If you want directly measured free hormones, the Essential Thyroid Panel (TSH + Free T4 + Free T3) is the modern equivalent. **Clinical use:** Classic 4-test thyroid panel: TSH, Total T4, T3 Uptake, and a calculated Free T4 Index (FTI). Screens for hypothyroidism and hyperthyroidism; FTI corrects Total T4 for binding-protein effects to estimate free hormone activity. ## Who should order it? Anyone screening thyroid function with persistent symptoms (fatigue, weight changes, hair loss, cold intolerance, palpitations), or tracking trends against older results from this same classic panel. If you want directly measured free hormones instead of a calculated index, order [TSH + Free T4](https://www.test-well.com/tests/tsh-with-free-t4) or add [Free T3](https://www.test-well.com/tests/free-t3). ## Biomarkers measured - [TSH](https://www.test-well.com/biomarkers/tsh) - Total T4 (Thyroxine) - T3 Uptake - Free T4 Index (FTI) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $36.99 | $42.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $46.99 | $52.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served. Prices are identical online and in the lab; no draw fee or physician fee is added. ## How much does a Thyroid Panel with TSH test cost? A Thyroid Panel with TSH test costs $36.99 at TestWell — $42.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the closest equivalent lists at $149.00 at Quest Health and $89.00 at Labcorp OnDemand (list prices checked Sep 12, 2026; see the notes on how the products differ). Hospital outpatient labs typically bill around $200.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. | Where you order | Price | One test, all-in | Notes | | --- | --- | --- | --- | | TestWell (drawn at Quest or Labcorp) | $36.99 | $42.99 | Includes the one $6 lab processing fee, charged once per order | | Quest Health (Quest Diagnostics' own site) | $149.00 | $149.00 | Marker lists differ; both are TSH-anchored thyroid panels · [list price checked 2026-09-12](https://www.questhealth.com/product/comprehensive-thyroid-test-panel/18659M.html) | | Labcorp OnDemand (Labcorp's own site) | $89.00 | $89.00 | Marker lists differ; both are TSH-anchored thyroid panels · [list price checked 2026-09-12](https://www.ondemand.labcorp.com/lab-tests/thyroid-test) | | Hospital outpatient lab, self-pay (typical) | $200.00 | $200.00 | Reference figure; hospital charges vary widely by facility and are often higher | Lab test codes: Quest test code 7444 · Labcorp test no. 000620. ## How do you prepare?

No. This is the classic fixed panel Quest and Labcorp have offered for decades — it reports Total T4 (all thyroxine, bound and unbound) plus T3 Uptake, and calculates a Free T4 Index (FTI) from those two values to estimate free hormone activity. If you want directly measured free hormones, order [TSH + Free T4](https://www.test-well.com/tests/tsh-with-free-t4) ($27.99) or [Free T3](https://www.test-well.com/tests/free-t3) instead — modern free-hormone assays are separate tests, not part of this panel. ### Why order a thyroid panel instead of just TSH? TSH alone catches most primary thyroid disease, but adding Total T4, T3 Uptake, and the calculated FTI helps confirm whether an abnormal TSH reflects true hormone excess or deficiency, and flags binding-protein effects (pregnancy, estrogen therapy) that can distort Total T4 readings. ### How much does a Thyroid Panel cost without insurance? TestWell charges $36.99 ($46.99 at Labcorp draw sites) — vs $65 for the same panel at Quest Direct and $100-$250 at hospital outpatient labs. ### Do I need to fast? No fasting required, but if you take levothyroxine, draw before your morning dose for consistency. ### What's the CPT code for a Thyroid Panel? 84443 (TSH) + 84436 (Total T4) + 84479 (T3 Uptake). The Free T4 Index is calculated from Total T4 and T3 Uptake, so it carries no separate CPT code. HSA/FSA eligible as a bundle. ### Should I add thyroid antibodies? If you have a family history of autoimmune thyroid disease or symptoms despite normal TSH, add [TPO Antibodies](https://www.test-well.com/tests/tpo-antibodies) to screen for Hashimoto's — the most common cause of hypothyroidism in the US. ## How to order 1.
