Do I need a doctor to order hyperthyroidism labs?

No. JustLabs provides physician-authorized lab orders online. You can order TSH, Free T4, Free T3, and antibody tests without a doctor visit.

How much does hyperthyroidism lab testing cost?

TSH starts at $8. A panel with TSH, Free T4, and Free T3 costs about $25. Adding TPO antibodies brings the total to around $37.

How often should I test for hyperthyroidism?

If actively treating, every 4-8 weeks until stable. Once controlled, every 3-6 months. Your provider may adjust this schedule.

What does a low TSH mean?

A low or suppressed TSH (below 0.4 mIU/L) means your pituitary gland detects too much thyroid hormone in your blood, the hallmark of hyperthyroidism.

Can I use insurance for these tests?

JustLabs is self-pay with transparent pricing. You can submit receipts to your HSA or FSA for reimbursement.

Lab Tests for Hyperthyroidism

Hyperthyroidism occurs when your thyroid gland produces too much thyroid hormone, accelerating your metabolism and potentially causing weight loss, rapid heartbeat, anxiety, and tremors. Lab testing is critical for confirming hyperthyroidism, identifying its cause, and monitoring treatment. The hallmark finding is low or suppressed TSH with elevated Free T4 or Free T3. With JustLabs, you can order these tests directly online at self-pay prices, no doctor visit required. Results are typically available within 1-2 business days.
