Thyroid panel Plus + reverse T3

Tiredness that stays after a full night's sleep, weight changes with no clear explanation, constipation, palpitations or an unusual sensitivity to cold or heat are the reasons people check their thyroid. For women, changes in the cycle join that list.

TSH is the signal your brain sends to the thyroid, and free T4 and free T3 are the hormones the thyroid puts into circulation. Reading them together shows whether the regulation and the response move together or one of them has fallen behind, and that is the starting point of any thyroid panel.

The hormones say how the thyroid works today. Anti-TPO and anti-thyroglobulin antibodies point to a possible cause: an autoimmune process such as Hashimoto's thyroiditis. They can appear while TSH and the hormones are still within range, so they add a layer the hormones alone do not show.

A positive result does not by itself mean you have an underactive thyroid or need medication. It is read together with the hormones, your symptoms and your history. Other situations, such as Graves' disease, need different antibodies that this panel does not include.

Reverse T3 is the value that sets this panel apart from the Thyroid panel Plus. Many people search for it by name and end up ordering it separately, at another laboratory or on another day. Here it goes with the rest, next to TSH, free T4, free T3 and the antibodies, so you read it alongside them rather than on its own.

This panel is usually done when you have already checked your thyroid, the symptoms are still there and you want a wider picture than TSH alone. Also when you are looking, directly, for a panel that includes reverse T3, or when you want to repeat an earlier result with every value at once.

If you only want function and antibodies, our Thyroid panel Plus covers the same values without reverse T3.

You buy it online, receive your authorisation by email and go to our partner laboratory. The laboratory gives you the access to check and download your result when it is ready. No waiting list, and the full price shown before you pay.

What does the thyroid panel with reverse T3 include?

TSH, free T4, free T3, reverse T3 and anti-TPO and anti-thyroglobulin antibodies. It is everything in our Thyroid panel Plus plus reverse T3.

How is it different from the Thyroid panel Plus?

By one value: reverse T3. The rest is identical. If you do not need it, the Thyroid panel Plus is the same panel without it.

Can I have positive antibodies and normal hormones?

Yes. The antibodies can be present while thyroid function is still normal. That is why this panel measures them together with the hormones.

Does it cover Graves' disease?

No. Graves' disease is studied with other antibodies that are not in this panel.
