Normal biochemical parameters refer to the typical or standard values of various substances in the body that are measured through biochemical tests. These tests are commonly performed in clinical laboratories to assess the functioning of organs and systems, diagnose diseases, and monitor treatment effectiveness. Normal ranges can vary slightly between different laboratories, so it’s essential to interpret results in the context of the specific reference values provided by the testing facility. Here are some common biochemical parameters and their normal ranges:
