LAB VALUES IN 5: Aspartate Aminotransferase for NCLEX

Aspartate Aminotransferase (AST) — the must-know liver lab value for the NCLEX, covered in 5 minutes.

In this episode: what AST measures, the normal reference range of about 8-40 (ranges differ slightly for males and females), how AST is found in the liver plus the heart, skeletal muscle, kidneys, brain and red blood cells — and how that differs from ALT which is mostly just in the liver, why AST is part of the liver function tests (LFTs) alongside ALT, bilirubin and protein, when it's ordered including liver disorder symptoms like jaundice, abdominal swelling, nausea, vomiting, weakness, fatigue, loss of appetite, itching and darker urine, at-risk patients like those exposed to hepatitis, heavy drinkers, drug use, overweight and diabetes, how high AST climbs in viral hepatitis (up to 10 times normal) versus chronic hepatitis (4-5 times normal), and other causes of elevated AST like myocardial infarction and kidney disease.

Keywords: AST, aspartate aminotransferase, normal range, reference range 8-40, elevated AST, liver function tests, LFTs, liver panel, amino acid metabolism, viral hepatitis, chronic hepatitis, myocardial infarction, kidney disease, jaundice, ALT vs AST, bilirubin, NCLEX lab values, nursing labs.
