Hi doctors im 20 years old male and in a good health, recently i went to blood bank for donation, the hgb was good, 14.5g/dl, and the other values were all good,The hct was 43% but the doctor said that hct should be 45 and above , and then asked me if i want to donate, and i told him "you know better", he told me not to donate now and come back later to check the hct. Any comments docs ? I eat garlic regularly one in the morning about 3 times a week since 2 months just for its benefits, does garlic affect the hct ? Thanks.
