Biological samplesBlood assays ⏵ Blood biochemistry


A range of key biochemistry markers were measured in the blood sample collected at recruitment (for all 500,000 participants) and at repeat assessment approx. 5 years later (for 20,000 participants). The biomarkers were selected for analysis because they represent established risk factors for disease, are established diagnostic measures, or characterised phenotypes not otherwise well assessed and are feasible to measure at scale.
