Cholestasis test

Did you fast? I just got tested and worried about getting an accurate result because my doctor told me to fast but then I looked at the website for cholestasis and it says fasting isn’t needed and can lead to lower levels which can cause you to miss a diagnosis. If my labs come back normal should I ask to be retested? I’m having itchy palms and soles of my feet at night as well as pain behind my right shoulder blade on my back that keeps getting worse everyday.

Btw if you happen to be in the U.S. how long did it take your results? Does it actually take a week? I get all my other labs back in like 24 hours or less, I’m in California and have Kaiser insurance
