Hi. can drinking alcohol around 48-72 hrs before a blood test show low white blood count only by 0.5. thanks. ?

Are you asking...: ...whether your blood count dropped by 0.5, or that your total white count is 0.5 (a much more serious issue)? Also, alcohol can affect bone marrow function--how much have you been drinking to warrant your question?

No: A significantly low white count would not be expected a day or two after drinking alcohol. Prolonged heavy drinking for years can cause an effect on the bone marrow and lower the white count.is significantly low white count needs a evaluation by hematologist a blood specialist
