Analyzing the protein content of body fluids such as blood, urine, or cerebrospinal fluid (CSF) is known as protein (fluid) evaluation. This test helps diagnose diseases such infections, inflammation, liver disease, kidney disease, and nutritional deficits. It counts the amount of each type of protein as well as the total amount of protein in the fluid sample. Protein levels that are abnormal can point to underlying medical conditions. For example, high urine levels may indicate renal damage, while low blood levels may indicate malnourishment or liver disease. It is necessary to take into account the clinical history, symptoms, and further lab results when interpreting results. “(HHD)” designates the specific context or test version, sometimes mentioning a particular hospital or healthcare provider. Protein levels should be regularly monitored to track the course of an illness or the response to treatment. This allows for timely interventions to improve
