Medical test Guide, Meaning , Facts, Information and Description

A medical test is any kind of diagnostic procedure performed for health reasons. For example:

• to diagnose diseases
• to measure the progress or recovery from disease
• to confirm that a person is free from disease

Some medical tests are parts of a simple physical examination which require only simple tools in the hands of a skilled practitioner, and can be performed in an office environment. Some other tests require elaborate equipment or the use of a sterile operating theatre environment.

Some tests require samples of tissue or body fluids to be sent off to a pathology lab for further analysis. Some simple chemical tests, such as urine pH, can be measured directly in the doctor's office.

Most medical tests are conducted on the living; however, some of these tests can also be carried out on a dead person as part of an autopsy.
