What is diagnostic tests?

A diagnostic test is a test used to identify the presence or absence of a disease or condition. It is used to confirm or rule out a diagnosis, or to monitor the progress of a disease or condition. Diagnostic tests may include blood tests, urine tests, imaging tests, and biopsies.

Blood tests are used to measure the levels of various substances in the blood, such as hormones, enzymes, and electrolytes. These tests can help diagnose various conditions, such as anemia, diabetes, and thyroid problems.

Urine tests are used to analyze the composition of urine, which can help diagnose conditions such as urinary tract infections, kidney disease, and diabetes.

Imaging tests use X-rays, ultrasound, MRI, and CT scans to create images of the inside of the body. These tests can help diagnose conditions such as tumors, fractures, and bleeding.

Biopsies involve removing a small sample of tissue from the body for examination under a microscope. This can help diagnose conditions such as cancer, infections, and autoimmune diseases.

Diagnostic tests can be used to confirm or rule out a suspected diagnosis, to monitor the progress of a disease or condition, to screen for diseases in people who are at risk, and to predict the outcome of a disease or condition.
