There are numerous medical tests available that are routinely used for investigating and diagnosing disease. This section describes the most common screening and diagnostic procedures and explains why and when they are used.
Tests on the composition of blood are some of the most common methods used to look for disease and may also be done routinely to assess general health. They may be carried out on any blood component: red blood cells, white blood cells, tiny cells called platelets, and proteins, all of which are carried in liquid plasma.
Studies of individual cells or of a larger sample of tissue containing different cells are among the most important tests carried out.
Although genetic tests are less frequently performed than other types of test, the results may have profound effects on your life.
Imaging techniques aim to provide detailed and reliable pictorial information about structures within the body.
Identifying microorganisms responsible for disease is an essential step in the diagnosis and treatment of infectious illnesses.
Obtaining most types of test samples is simple and painless and may be carried out as part of a doctor's visit or by yourself at home.
Viewing structures or organs in the body is often important for screening, diagnosis, or monitoring disease.
During the visit, your doctor will ask various questions and carry out an examination to take the first steps towards a diagnosis.
