What does Albumin testing primarily diagnose?

Albumin testing is primarily used to assess and diagnose a variety of disorders related to the liver, kidneys, and overall nutritional status. Albumin is a protein produced by the liver, and its levels can indicate several conditions. For instance, low levels of albumin may suggest liver disease, such as cirrhosis or hepatitis, as well as kidney disorders that lead to protein loss, such as nephrotic syndrome. Additionally, albumin levels can be influenced by nutritional status, indicating malnutrition or conditions that cause inflammation. Therefore, the breadth of conditions that albumin testing can help diagnose justifies the choice of "a variety of disorders" as the correct answer. Other options are too specific or unrelated to the purpose of albumin testing.
