Serum glucose levels may be abnormally high (hyperglycaemia) or abnormally low (hypoglycaemia). Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolic disorders including diabetes mellitus.

Glucose is the form of sugar that is transported around the body in blood to provide energy for all bodily functions. A very common blood test, but an essential part of any health screening, high levels are diagnostic of diabetes mellitus, a state in which the body is unable to handle glucose adequately. Low levels can occur in healthy individuals on occasion, but if sustained, a low level of glucose may indicate an underlying problem with how sugar levels are maintained by the body. As we recommend that you fast for your health screening this will be reported as a FASTING blood glucose level.
