Clinical Chemistry is a specialized field of medical laboratory science. It involves analyzing chemical components of body fluids and tissues to aid in the diagnosis, treatment and prevention of diseases. Clinical chemists use a variety of techniques and instruments to detect and measure different substances in biological samples, such as blood, urine, and cerebrospinal fluid. They provide critical information to physicians to help them make accurate diagnoses and monitor patient health. This field also involves research to develop new tests and technologies that can improve patient care.
