Lab tests, a crucial component of medical diagnostics, involve the analysis of various bodily samples such as blood, urine, or tissue to assess health status, detect diseases, or monitor treatment effectiveness. 

These tests encompass a wide range of parameters including blood counts, cholesterol levels, liver and kidney function, glucose levels, and infectious disease markers. Results help healthcare providers make informed decisions about diagnosis, treatment plans, and preventive measures, ensuring comprehensive care tailored to each individual’s needs.
