[Abnormal hemoglobins in a Negroid population in Peru]

A study was performed on 100 blood samples from black people native of the Chincha province and living in Pueblo Nuevo Ica district, in Peru. No haematological abnormalities were seen in any of the cases. Upon haemoglobin electrophoresis, 8 carriers of abnormal haemoglobin were found, the A/S pattern appearing in 5 instances and the A/C pattern in 3. These 8 samples were subjected to deoxyhaemoglobin solubility tests and to differential solubility test with urea, the initial results being confirmed. These data correlate, in general terms with previous findings.
