Will alcohol 24 hrs before a blood test show low hemogoblin levels? Male 23yo 56kg. Not too much protein in diet. Thanks.

If anemic. If a person is anemic, his hemoglobin test result will be low, regardless of whether or not he drank alcoholic drinks the day before. Likewise, if he is not anemic, his hemoglobin result will not be low, regardless of the alcoholic drinks he had the day before.
