Can you detect thyroid problems?

Yes, our blood work may detect thyroid dysfunction.

The Advanced blood test (included in Advanced and Pro packages, or bookable standalone) includes a full thyroid panel: TSH, free T3 (fT3), and free T4 (fT4). These markers may reveal hypothyroidism, hyperthyroidism, or subclinical thyroid dysfunction (early imbalances before symptoms appear).

However, we do not currently test anti-TPO or anti-thyroglobulin antibodies, which are needed to diagnose autoimmune thyroid conditions like Hashimoto's thyroiditis or Graves' disease. If your thyroid hormone levels come back abnormal, your GP can order antibody tests as a follow-up.

Our MRI does not specifically assess the thyroid gland. The neck is included in the scan, so large structural abnormalities might be incidentally detected, but dedicated thyroid imaging requires an ultrasound.
