What are biomarkers?
Biomarkers refer to biological molecules found in your blood that are a sign of a normal or abnormal process, or a condition or disease. They can be used for screening and disease progression monitoring, and to guide and assess treatment responses.
For example, hs-CRP levels in the blood can be used as a biomarker for inflammation, while cholesterol levels can indicate heart disease risk. You can also track hormone levels in your blood to monitor things like perimenopause, PCOS and fertility. You can view all of our home blood tests here.
