A clinic blood test measuring TSH, T3 and T4 together, commonly used to help assess whether the thyroid is underactive or overactive.
3 biomarkers as listed by Better2Know.
Thyroid stimulating hormone (TSH) is released by the pituitary gland to tell the thyroid how much hormone to produce, while T3 and T4 are the hormones the thyroid makes in response. Measuring all three together is commonly used to help assess whether the thyroid is underactive or overactive, or to monitor a known thyroid condition.
There is no comparison group recorded for this exact test in our system, so we cannot rank it against named competitors. Against the wider set of similarly sized thyroid panels we track, its £160 price is well above the typical £65, which is the main reason its value for money score is so low.
Clinical depth scores solidly for a three-marker panel around the middle of the thyroid tests we track. Collection convenience is more modest, since it requires a clinic visit with no home-kit option listed for this test. Results and follow-up also scores modestly because results are not doctor-reviewed as standard.
This suits people who want a clinic-based check of TSH, T3 and T4 together, for example if a GP has asked for a fuller thyroid picture or you are monitoring a known condition. There is no comparison group recorded for this exact test, so we cannot point you to a specific cheaper equivalent; if price matters most, it is worth comparing against the wider range of three-marker thyroid panels on the market, which we track at a typical £65. See a GP about symptoms or an abnormal result.
A clinician takes a venous blood sample from you at a Better2Know clinic and sends it to the lab for analysis of TSH, T3 and T4. Results are typically ready within a day, and you can track progress through the online Patient Area or opt for an SMS or email alert. Results are not doctor-reviewed as standard.
