Anemia is a condition that describes the levels of hemoglobin (Hgb) or the number of erythrocytes (red blood cells) in the blood is less than normal value. A person suffering from anemia when Hgb less than 13.5 in men and in women is less than 12.0, and hematocrit (HCT) in men less than 41 and in women less than 36.
To know a person suffering from anemia or not, need to be examined in the laboratory by means of blood sampling.
