I drank alcohol 5 days ago, will that show up on an accutane blood test, or will that affect the Accutane blood panel?

unless you drink frequently it wont show up. It's not safe though. Stop doing that if you like your liver and want to enjoy a cocktail after you finish accutane ;)

We generally recommend against taking alcohol with accutane. It will not show on the blood test and don’t bing drink (that’s having more than 4 drinks for women and 5 drinks for men) as it’s generally bad for your health and liver. Elevated liver enzymes do show up if you drink excessive alcohol for a long period of time.

Thank you for your question. Drinking alcohol prior to labs for Accutane may increase your liver enzymes, and I highly recommend you make your dermatologist aware of the alcohol intake. Take care and good luck.
