Diagnostic test

A diagnostic test is a tool used by healthcare professionals to identify whether someone has a specific medical condition or disease. It involves analyzing a sample of blood, urine, tissue, or other substances, or using imaging methods like X-rays or scans. The results help doctors determine the cause of symptoms, confirm a diagnosis, or rule out certain conditions. Diagnostic tests are essential for guiding appropriate treatment decisions and ensuring patients receive the right care based on accurate information about their health.
