TSH W/ Reflex to T4 Free (additional cost for reflex)
The TSH with Reflex to Free T4 test begins by measuring thyroid-stimulating hormone (TSH) to screen for thyroid dysfunction. If the TSH result is outside the normal range, Free T4 testing is automatically performed to provide additional information about thyroid hormone production.
This reflex testing approach helps streamline thyroid evaluation, reduce unnecessary testing, and support accurate diagnosis. It is commonly used for routine thyroid screening and initial assessment of symptoms such as fatigue, weight changes, temperature sensitivity, or heart rate abnormalities.
