Fluid analysis is the examination of bodily fluids, such as blood, urine, or cerebrospinal fluid, to diagnose medical conditions. This process helps healthcare professionals identify infections, diseases, and other health issues by analyzing the composition and characteristics of the fluids. The analysis can include various tests, such as blood tests, urinalysis, and biochemical assays, which provide valuable information about a person's health. By interpreting the results, doctors can make informed decisions about treatment and management of the patient's condition.
