Vitamin B12 (active form) test

Check your active vitamin B12 levels with our quick, easy-to-use blood test kit. You take a simple finger prick test and we'll analyse your sample at one of our UKAS accredited labs in the UK. This B12 blood test kit measures the active form of B12 specifically (as opposed to total B12). This is the most accurate way to measure your available level of vitamin B12 and is the best early indicator of any possible deficiency. Vitamin B12 (along with folate) plays an essential role in the formation of red blood cells and also has an important role to play in nerve health. The human body does not produce its own vitamin B12 , so it has to be absorbed through diet. Low levels of this essential vitamin can leave you feeling tired and weak while prolonged deficiency can also lead to anaemia.
