Brief Answer:
may be related to crestor

Detailed Answer:
HI, thanks for using healthcare magic

It is possible that the crestor contributed to this increase, statins are a well known cause of increases in liver enzyme levels.

Another common cause is NON alcoholic fatty liver disease. This is the build up of fat in the liver that is not associated with alcohol use. It is related to diet, activity , weight.
If this is present that it could also contribute to the increase.

If the value of your AST is less than 3 times the upper limit of the normal range at your lab, then the statins can be continued. This is confirmed in an article in XXXXXXX association of family physicians.
In many cases, the increase in these values can resolve on their own. They do not necessarily indicate that the liver is in danger

Depending on your value (how high it is, not stated above), and your risk of heart disease or stroke, your doctor would decide the next course of action.

Other liver enzymes and an ultrasound may be done, depending on the value.

I hope this helps, feel free to ask any other questions

Brief Answer:
this would be in normal range for most labs

Detailed Answer:
Hi

The normal upper limit of AST for most labs is 40.

This may be different for your lab so you can check to see its upper limit.
It should not be far from 40.

At 37, your value could only be slightly higher from the upper limit, if it is even above it at all.

Based on this alone, you do not likely have any significant liver disease at all
