Biological testing refers to the process of analyzing biological samples, such as blood, urine, or tissue, to assess health, diagnose diseases, or evaluate the effects of treatments. This testing can help identify infections, genetic disorders, or the presence of harmful substances in the body. Common methods used in biological testing include blood tests, urinalysis, and biopsy. These tests provide valuable information to healthcare professionals, enabling them to make informed decisions about patient care and treatment options. Accurate biological testing is essential for effective medical diagnosis and monitoring.
