Why this panel

Thyroid disease is common, easy to miss, and reproduces the symptom list of a dozen other conditions. These two markers rule the common cases in or out.

💡 What most people missTSH alone — which is what most screening uses — misses people. TSH is a pituitary hormone, so it's an indirect read. Adding free T4 tells you whether the thyroid is actually keeping up, and distinguishes subclinical from overt disease. That distinction changes whether treatment is even appropriate.
⏰ When to get it drawnMorning. Stop biotin 72 hours before — it's in nearly every hair and nail supplement and it makes TSH read falsely low and T4 falsely high. This is the single most common cause of a bizarre thyroid result.

The 2 markers — and why each one is here

TSH (Thyroid-Stimulating Hormone) $9.00
The screening marker — but indirect, and it misses people alone
Free T4 (Free Thyroxine) $13.00
Shows whether the gland is actually keeping up
✓ How to read the resultsHigh TSH with normal free T4 is subclinical hypothyroidism — often monitored rather than treated. High TSH with low free T4 is overt and gets treated. Low TSH with high free T4 is hyperthyroid and needs a doctor promptly.
