A decade-by-decade clinical guide to AST (aspartate aminotransferase) interpretation, covering normal ranges, optimal targets, the AST/ALT ratio, and when to act on an abnormal result.
Aspartate aminotransferase (AST) reference ranges flag disease, but longevity medicine asks a sharper question: what AST level is associated with the lowest all-cause mortality and best metabolic health? This guide covers the evidence, the AST/ALT ratio, and the numbers your clinician should be targeting.
A clinical deep-dive into how common medications raise or lower AST, what the optimal AST range looks like, and when an abnormal result requires action. prepared by the HealthRX.com Editorial Team.
How diet, fasting, and exercise affect AST levels, what the optimal AST range is, and when elevated readings signal true liver stress versus normal physiological variation.
Learn how to interpret AST rate-of-change, optimal AST ranges, and what rising or falling AST trends mean for liver health, TRT, GLP-1 therapy, and longevity medicine.
AST levels differ meaningfully by sex, menstrual cycle phase, and hormonal status. This evidence-based guide covers normal ranges, optimal targets, AST/ALT ratio interpretation, and how estrogen, testosterone, and progesterone shift your baseline.
Intense exercise raises AST by releasing the enzyme from muscle, not liver. Learn the normal AST range, how much elevation is expected after training, when elevated AST signals true liver injury, and what the AST/ALT ratio tells your clinician.
