What’s in the panel
Four markers — the picture TSH alone often misses
Most primary-care offices order TSH first and stop there. A TSH-only screen can miss conversion problems and autoimmune patterns. Our panel covers all four together so you get a complete picture in one draw.
TSH
Thyroid-Stimulating Hormone
Signals from the pituitary gland that tell the thyroid how much hormone to produce. The most common single thyroid screen.
Free T4
Free Thyroxine
Storage hormone the thyroid produces. Most converts to T3 in tissues. Useful when TSH alone gives an unclear picture.
Free T3
Free Triiodothyronine
Active thyroid hormone in tissues. Important when investigating conversion problems or persistent symptoms.
TPO + TgAb
Thyroid antibodies
Markers of autoimmune thyroid disease — Hashimoto’s or Graves’. Positive antibodies can precede TSH changes by years.
When to test
The most common reasons adults book thyroid testing in Ashburn
- Persistent fatigue, weight changes, or feeling cold — classic signs of hypothyroidism. Worth a baseline panel even if your TSH was normal last year.
- Hair thinning, dry skin, or constipation — common in low thyroid function. The four-marker panel can catch issues TSH alone misses.
- Racing heart, weight loss, anxiety, or heat intolerance — possible signs of hyperthyroidism. The panel includes antibodies that flag autoimmune Graves’ disease.
- Monitoring thyroid medication — clients on Synthroid, Armour, or similar typically re-test every 6 to 12 months. Take your medication as normal on the day of the draw.
- Family history of thyroid disease — autoimmune thyroid disease runs in families. Baseline antibodies can flag risk years before TSH shifts.
- Pregnancy or planning a pregnancy — thyroid function matters for fertility and pregnancy outcomes. Coordinate testing with your OB.

FAQ
Thyroid testing questions, answered
Common questions about thyroid panels at our Ashburn lab. Don’t see yours? Call us at 571-500-7030.
What is included in a comprehensive thyroid panel?
Our comprehensive thyroid panel covers TSH (thyroid-stimulating hormone), Free T3 (active thyroid hormone), Free T4 (storage thyroid hormone), and thyroid antibodies (TPO and TgAb). Together they give a full picture of thyroid function and autoimmune involvement.
Do I need to fast for a thyroid blood test?
No. Thyroid panels do not require fasting. Take your morning medications normally — including thyroid replacement (Synthroid, Armour, etc.) — unless your prescriber has specifically instructed otherwise.
My TSH is normal — why am I still tired?
TSH alone can miss conversion problems or autoimmune patterns. That is why our panel includes Free T3, Free T4, and antibodies — the four together give a much more complete picture than a TSH-only screen. Discuss results with a primary-care or endocrinology provider.
How fast will I get my thyroid results?
Thyroid panel results post to your secure online portal within 24 to 72 hours after the blood draw. You can share or print the report directly from the portal and bring it to any provider you choose.
Should I get a thyroid test if I am on Synthroid or other thyroid medication?
Yes — clients on thyroid replacement often re-test every 6 to 12 months to track dose effectiveness. Take your medication as normal on the day of the draw unless your prescriber has given different instructions.
