[3 new cases of Korle-Bu hemoglobin in the Antilles].

After the case of haemoglobin Korle-Bu found in Martinique by Bookchin (2) in 1970, we have also detected one case of haemoglobin S/Korle-Bu in 1975 from a man native of Martinique. A family study allowed us to find again this abnormal haemoglobin from his two children with the form A/Korle-Bu. We study the different possibilities to detect haemoglobin S/Korle-Bu by singlet ests of laboratory whose some ones do appear antagonist effect given by haemoglobin Korle-Bu for haemoglobin S.
