Medical diagnostics

Definition

Medical diagnostics is the process of identifying a disease or condition through examination, testing, and analysis of patient data. It plays a critical role in guiding treatment decisions and improving patient outcomes by accurately determining the nature and extent of medical issues. With advances in technology, methods such as imaging, laboratory tests, and molecular techniques are increasingly utilized to enhance the accuracy and efficiency of diagnoses.
