Is your friend doing okay? First link shows Vitamin D is very low and should be affecting your friends energy levels at the very least. Second link shows a 1500%(!) increase in AST in under a year and its way over limit. One way to evaluate the accuracy is the sniff test, e.g. is the lab result congruent with how the person feels? Information on the internet around understanding your medical tests is pretty crappy unfortunately, but you can usually get to understand whether symptoms match. And if you have a doctor that gives you the time of day and helps you understand it, even more so. Your friend's AST result raises a question of whether there is an accuracy issue and should be investigated. From WebMD [0] -- > High levels of AST may be caused by: > * Liver damage from conditions such as hepatitis or cirrhosis. > * A heart attack or heart failure. > * Many medicines, such as statins, antibiotics, chemotherapy, aspirin, narcotics, and barbiturates. > * High doses of vitamin A. > * Kidney or lung damage. > * Mononucleosis. > * Some types of cancer. > Many different conditions can raise AST blood levels, so other testing is usually needed to interpret an abnormal AST result.
