A physician going over results on a tablet with a patient

Most thyroid testing ends at TSH, which can look completely normal while the rest of the picture isn’t. We run the whole panel, antibodies included, so an autoimmune pattern is caught early.

Reading the whole panel

Free T3 and free T4 show the hormone your body can actually use. Antibodies show whether the immune system is involved. Together they explain what one number can’t.

A physician reads every thyroid result and flags anything that belongs with an endocrinologist.

How is Tinsdale different from my yearly physical?

A routine physical looks at about 20 markers. Tinsdale runs 150+ biomarkers, and a licensed physician goes through every result with you and turns it into a clear, personal plan.

Do I need to fast before my blood test?

For most panels, yes: nothing but water for 8–10 hours first. Water actually makes the draw easier. Your exact prep notes arrive with your booking.

How soon will I get my results?

Most results are back within 48 hours of your sample reaching the lab, and we notify you as soon as your physician-signed report is ready.

Can I collect my sample at home?

Yes. Book a home visit anywhere inside I-495 and a certified phlebotomist comes to you, or walk in at one of our three labs.

Is my health data private and secure?

Yes. Your data is encrypted, kept on HIPAA-compliant systems and never sold, and you choose who gets to see your results.

Does insurance cover Tinsdale?

Tinsdale is direct-pay with prices posted up front. Many members pay with HSA or FSA funds, and we send an itemized receipt for reimbursement.
