Priciest 2-marker thyroid kit in its group
An at-home finger-prick test checking FT4 and TSH, the two core thyroid hormones, for people who want a thyroid function check without a clinic visit.
Same three markers as rivals, priced far above them
Checks the three core thyroid hormones, TSH, FT4 and FT3, from a home finger-prick blood sample. Suits anyone wanting a full first-line thyroid check rather than TSH alone.
Pricier than most 2-marker thyroid tests, no FT3 included
A blood test measuring TSH and FT4, the two hormones commonly used to assess thyroid function. Suited to anyone monitoring a known thyroid issue or investigating symptoms such as fatigue with a GP.
More than double the median price for a single marker
Measures serum selenium, a mineral linked to thyroid function, immune health and antioxidant protection. Suited to those with a specific interest in this one marker.
Clinic thyroid panel measuring TSH, FT3 and FT4
A three-marker blood test covering TSH, FT3 and FT4, giving a broader picture of thyroid function than a single marker alone.
Single thyroid marker with a slow 20-day US lab turnaround
Reverse T3 is a thyroid-related marker sometimes tested alongside Free T3, though the provider's own description notes debate over how useful it is for guiding treatment. It suits people who specifically want this marker rather than a standard thyroid panel.
Costs far more than its two thyroid-antibody rivals
A blood test that measures thyroid peroxidase antibodies, commonly used to assess autoimmune activity against the thyroid gland.
Same marker count as rivals, at a far higher price
A 5-marker thyroid panel covering TSH, free T4, free T3 and two thyroid antibody tests, using a clinic or nurse-visit blood draw. Suits people with thyroid symptoms wanting antibody testing alongside the core hormones.
Three-marker thyroid panel, no home option listed
A clinic blood test measuring TSH, T3 and T4 together, commonly used to help assess whether the thyroid is underactive or overactive.
Single-marker PTH test, in-clinic sample only
A single-marker blood test for intact parathyroid hormone (PTH), commonly used to help assess parathyroid gland function and calcium regulation. Requires an in-person clinic visit.
