Thyroid Test
Cheapest full 3-hormone thyroid panel
A three-hormone blood test measuring TSH, FT4 and FT3, the standard panel used to check for an underactive or overactive thyroid.
- At-home test
A 5-marker at-home finger-prick test checking thyroid function and thyroid antibodies, aimed at anyone with possible under- or overactive thyroid symptoms.
This test checks thyroid function and thyroid antibodies using a finger-prick blood sample. Thyroid hormones are commonly used to assess how the thyroid gland is working, and antibody testing can help identify autoimmune thyroid conditions, though testing alone does not diagnose a condition and ongoing symptoms are best discussed with a GP.
Forth does not publish the names of the 5 biomarkers included, which makes it harder to compare directly against other thyroid tests marker by marker. On price, it sits about 4% below the £71.73 median across the 30 similarly sized thyroid tests we track, and the biomarker count puts it in the 64th percentile of thyroid tests overall.
Clinical depth scores reasonably well given that percentile position, and collection convenience is rated highly because the test can be done entirely at home with a finger-prick kit. clarity and documentation scores lower than most Forth tests because the biomarker list and report format are not published. Results and follow-up score well because a doctor reviews the results.
This suits anyone with possible thyroid symptoms, such as unexplained tiredness, weight changes or mood changes, who wants an at-home check before deciding whether to see a GP. Because the specific markers are not listed, anyone who wants to know exactly what will be tested before buying may want to check with Forth directly or compare against a provider that publishes its full thyroid marker list.
You collect a finger-prick blood sample at home, or you can arrange an AutoDraw device sample, a home nurse visit or a venous draw at a partner clinic. Results are returned within 2 days and reviewed by a doctor before you see your report.
