Diagnostic Testing

Diagnostic testing (pronunciation: /daɪəɡˈnɒstɪk ˈtɛstɪŋ/) refers to a wide range of medical tests and procedures used to identify and monitor diseases, conditions, or abnormalities.

Etymology

The term "diagnostic" is derived from the Greek word "diagnostikos," meaning "able to distinguish," and "testing" originates from the Old French "test," meaning "small vessel."

Types of Diagnostic Testing

Diagnostic testing can be categorized into several types, including:

• Laboratory Tests: These tests analyze samples of blood, urine, or tissue to help diagnose diseases or conditions. Examples include Complete Blood Count (CBC), Urinalysis, and Biopsy.

• Imaging Tests: These tests use various forms of energy, such as X-rays, sound waves, or radioactive waves, to create detailed images of the inside of the body. Examples include X-ray, Ultrasound, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI).

• Genetic Tests: These tests look for certain genes, chromosomes, or proteins that may be linked to disease. Examples include DNA Testing, Prenatal Genetic Testing, and Newborn Screening.

• Functional Diagnostic Tests: These tests measure the function of certain organs or systems in the body. Examples include Electrocardiogram (ECG), Pulmonary Function Test (PFT), and Stress Test.
