Measures TSH and free T4, the two core thyroid hormones, to help indicate an underactive or overactive thyroid. Suits anyone with symptoms like fatigue, weight change or mood changes who wants an initial thyroid check.
2 biomarkers as listed by MyHealthChecked.
This test measures two hormones: thyroid stimulating hormone (TSH) and free T4 (thyroxine). Together these are used to indicate whether the thyroid is underactive or overactive, conditions that can cause symptoms such as fatigue, weight change, hair loss or sensitivity to temperature.
Among the eight comparable thyroid tests we track, priced from £32 to £199 with a median of two markers, this £45 test matches the typical depth. Medichecks tests an extra marker, free T3, for the same £45, and Monitor My Health's three-marker test costs less, at £32.
The value for money score reflects a price 18% below the group median, and clinical depth is around the group average. Results and follow-up scores well because a GP reviews the results and provides recommendations.
This suits anyone with possible thyroid symptoms, such as fatigue, weight change or sensitivity to cold or heat, who wants a GP-reviewed check of the two core thyroid hormones. If you want free T3 included at no extra cost, Medichecks' Thyroid Function Blood Test tests three markers for the same £45; Monitor My Health's Thyroid Test also covers three markers, for less, at £32.
You take a finger-prick blood sample at home and post it to MyHealthChecked's UK laboratory. Results are ready in 2 to 3 working days, and a GP reviews them and provides recommendations.
