The serum albumin level is part of a standard panel of liver function tests (LFT) that also includes levels of plasma protein, bilirubin, alkaline phosphatase, alanine aminotransferase (ALT), and aspartate aminotransferase (AST). This is commonly ordered when liver disease is suspected as part of a comprehensive metabolic panel (CMP) in conjunction with the electrolyte panel known as the basic metabolic panel (BMP). In kidney disease, a CMP may be ordered as a follow-up test when proteinuria is detected by urine dipstick analysis, which may lead to a diagnosis of<unk> . Low levels of serum albumin are defined as less than 3.5 grams per deciliter, while clinically significant<unk>  is generally considered to be less than 2.5 grams per deciliter. Upon discovery of<unk> , a common work-up will include liver function tests to assess for liver disease, urine albumin and protein levels to assess for albuminuria and nephrotic syndrome, and brain natriuretic peptide to assess for cardiac failure. If protein-losing enteropathy is suspected based on clinical suspicion, an alpha-1 antitrypsin test can be performed. If stool alpha-1 antitrypsin is elevated, this suggests excessive gastrointestinal protein loss.
