Total protein in serum is a laboratory test used to measure the amount of proteins present in a patient's blood sample. Protein is an essential component in the body, playing a key role in building tissues, forming enzymes, and producing antibodies. Blood protein mainly consists of albumin and globulin, and this test reflects the balance of proteins in the body. Total protein in serum is used to assess liver and kidney function and can help diagnose conditions such as dehydration, infections, and chronic diseases. This test is usually performed as part of a routine panel and can provide valuable information about a patient's overall health. Abnormal results may indicate health issues that require further testing or follow-up.
