A laboratory test called “protein (fluid) analysis” is used to measure the amount of protein in different body fluids, including blood, urine, and cerebrospinal fluid (CSF). Numerous medical disorders, such as kidney and liver disease, infections, inflammation, and nutritional deficiencies, can be diagnosed and tracked with its assistance. The test counts the overall amount of proteins in the fluid sample as well as the particular kinds of proteins that are present.
