Abstract
The Inventors disclosed an inexpensive method of determining fetal hemoglobin (HbF) in red blood cells of individuals with sickle cell anemia undergoing hydroxyurea treatment. The method is based on the specific elution and measurement of sickle hemoglobin (HbS) from red blood cells, wherein the amount of HbF may be determined according to the formula: HbF=Total hemoglobin−HbS. The method may also be used to determine the amount of HbF in individuals without sickle cell anemia by the specific elution of adult or normal hemoglobin (HbA) from red blood cells whereby the amount HbF may be determined according to the formula: HbF=Total hemoglobin−HbA. The method will also determine levels of HbS or HbA in individuals with sickle cell and without sickle cell respectively. The methods have the advantage of being easy to practice in underdeveloped countries.
