ALT is an enzyme that checks on liver health. If one's liver cells are damaged due to excess alcohol, drugs, disease, or injury, ALT will appear in the bloodstream and, therefore, in a blood test.

Albumin is the most abundant protein in the blood and plays a vital role in maintaining fluid balance and transporting nutrients. Healthy albumin levels are critical for supporting bone health, as they influence calcium transport and overall bone metabolism.

ALP can help detect and/or monitor conditions related to the liver, malnutrition, autoimmune disorders, or bone disease. ALP is an enzyme that breaks down proteins. It is found throughout the entire body, but is mostly prevalent in the liver, bones, intestines, and kidneys.

AST is an enzyme mostly found in the liver and helps metabolize amino acids. Testing for AST in the blood can help detect liver damage from injury or a number of diseases and conditions, like hepatitis, cirrhosis, mononucleosis, or other liver diseases, heart problems, or pancreatitis.

Monitor liver health with GGT. This test helps detect liver disease, identify bile duct blockages, and check for conditions related to alcohol and toxins. The GGT biomarker is a reliable detector (but not a diagnostic test) for toxin exposure or fatty liver from alcohol, even when other liver tests are normal.

In tandem with a full liver panel, this test can help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, or blockage of the bile ducts. The liver makes bile to help digest food, and bile contains bilirubin. A healthy liver can get rid of bilirubin, but when the liver isn't working properly, it cannot break down bilirubin and dispose of it.

Total protein measures the combined levels of albumin and globulin in the blood. Adequate protein levels are essential for bone health, as proteins support bone matrix formation and repair while also reflecting overall protein status.

Globulin is a protein essential for liver function, blood clotting, and immune system operations. Abnormal globulin levels can indicate various conditions, such as liver disease, autoimmune disorders, or chronic infections.
