If you want an at-home thyroid test in the U.S., I’d favor a blood test that measures TSH + free T4, rather than a finger-prick test that only gives you TSH.
My top picks
1. Best overall: Labcorp OnDemand Standard Thyroid Test
It measures TSH and free T4, which is the combination the American Thyroid Association recommends for evaluating thyroid function. Labcorp uses a conventional laboratory blood draw, which is generally preferable to a home finger-prick sample for accuracy. It currently lists the test at $89.

2. Best if you specifically want to collect the sample at home: Everlywell Thyroid Test
This is a finger-prick blood spot test measuring TSH, free T4, free T3, and TPO antibodies, currently $149. It gives you considerably more information than a TSH-only test, particularly if you're wondering about Hashimoto's.
