There are several ways to measure glycated hemoglobin, of which HbA1c (or simply A1c) is a standard single test. [5] HbA1c is measured primarily to determine the three-month average blood sugar level and is used as a standard diagnostic test for evaluating the risk of complications of diabetes and as an assessment of glycemic control .
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The test works by taking a small blood sample of blood using a lancet (a sterile pointed needle) to prick a finger (Image 1). The blood droplet is usually collected at the bottom of a test strip, while the other end is inserted in the glucose meter. [6] The drop of blood is drawn into the meter and can directly measure the glucose in the sample.
A clinical chemistry analyzer; hand shows size. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments.

Many types of glucose tests exist and they can be used to estimate blood sugar levels at a given time or, over a longer period of time, to obtain average levels or to see how fast the body is able to normalize changed glucose levels. Eating food for example leads to elevated blood sugar levels.
This developing system of international mutual recognition agreements between accreditation bodies has enabled accredited laboratories to achieve a form of international recognition, and allowed test data accompanying exported goods to be readily accepted on overseas markets amongst the countries which have already qualified as significant to ...
Often, pathologists practice both anatomical and clinical pathology, a combination sometimes known as general pathology. Similar specialties exist in veterinary pathology . Clinical pathology is itself divided into subspecialties, the main ones being clinical chemistry , clinical hematology / blood banking , hematopathology and clinical ...
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test, are often grouped together into one test panel called a blood panel or blood work.
