Standard thyroid function screening blood test.
Based on typical US negotiated and cash-pay rates. Hospital charges can run significantly higher — often 2–10x these numbers. If your bill is well above this range, it's worth questioning.
- Billed with T3/T4 reflex tests that weren't clinically indicated by the TSH result.
T3/T4 are usually only medically necessary if TSH is abnormal. Check the sequencing.
