Why do different doctors give different fasting times for the exact same comprehensive metabolic panel? I've been told anywhere from 8 to 12 hours.
How long should you fast for a fasting metabolic panel? I keep hearing varying numbers. I'm assuming drinking water is ok at any point in time.
in general, fasting is greater than 8 hours, however most achieve at least 12 hours since labs are drawn at 8am and the patients meal (dinner) was the prior night at 8pm. This is done in order to get accurate lab tests and imaging. Water usually doesn't interfere with the lab tests however drinking too much or too little can alter your creatinine (kidney function), so would discuss with your physician if they are specifically looking at this number and want you to fast for a specific time. ...Read more

My husband's comp metabolic panel was: got=47 & gpt=84 both shown as elevated. What could this mean? And what further tests do you recommend? Thanks!
Abnormal liver tests: The SGOT and SGPT (now called ast and alt) are a bit elevated. These reflect your husband's liver function. I generally repeat the tests in a month, & ask patients to stop alcohol and Acetaminophen (tylenol) also. If the repeat test is still elevated, I usually test for hepatitis b & c. There are many medical conditions that can elevate liver enzymes - even weight; we search til we find a reason. ...Read more
