Clinical chemistry uses chemical methods to determine the levels in body fluids and tissues of chemical components. Blood and urine are the most important substances used in clinical chemistry.
There are several different methods for detecting and measuring nearly every form of a chemical component in the blood or urine. Blood glucose, electrolytes, enzymes, hormones, lipids (fats), other metabolic substances, and proteins may be components for diagnosing cancer.
Some of the commonest laboratory tests are as follows:
- Blood tests
