Does drinking alcohol 2 days before blood test alter the cholesterol?

Drinking alcohol. on a daily basis will affect the cholesterol profile, but it should not cause significant change if you drink once 2 days prior. The key is the continuous chronic nature of drinking. 1 glass of red/white wine daily may increase your good cholesterol (HDL) slightly while keeping your triglycerides and bad cholesterol a little lower. Chronic beer and liquor use will increase the total by a lot.
