Need results the same day? Our same-day blood test service covers core panels when your sample is taken before 14:00 and the lab confirms same-day reporting for that test.
The packages below were chosen by our GPs for routine monitoring and pre-MOT baselines: kidney and liver function, lipids, thyroid, iron, HbA1c, and the markers patients ask for most often at a Harley Street GP clinic.
