Why Do Blood Tests Need Fasting?

A blood test detects many disorders like anaemia, infection, and leukaemia. Some blood tests need fasting. Doctors advise the patients to fast before the blood is drawn out. This is because nutrients in food and drinks go into the bloodstream and alter some substances, which can change or distort the blood test reports. The diagnostic centre provides all the necessary information related to fasting. Search for ‘blood test near me’ to get the numbers of the nearest clinic.
