ABARCA, Gabriela et al. Hemoglobinas anormales en la población neonatal de Costa Rica. Rev. biol. trop [online]. 2008, vol.56, n.3, pp.995-1001. ISSN 0034-7744.

Abnormal haemoglobins in the newborn human population of Costa Rica. Hemoglobinopathies are hereditary autosomic recessive diseases. A total of 70 943 samples of whole blood collected by heel prick in filter paper (S&S 903) from throughout Costa Rica (October 2005-October 2006) were analyzed to detect variants of hemoglobin by the iso-electric focusing technique. Eight hundred ninety one cases presented some variant, for a frecuency of 1/79. Five cases are homozygous for hemoglobin S (sickle cell disease) and one shows the double heterozygous genotype SC. in this study the S and C variants of hemoglobin, although with some local differences, are widespread all over the country. Thus, the prevention of new cases is important through the testing of hemoglobin in the Costa Rican National Newborn Screening Program, together with a interdisciplinary National Program of Education for the disease and carrier status (AS/AC) for patients, families and medicar personnel. This is the basis for proper genetic counseling, to improve treatment and to reduce morbi-mortality. Rev. Biol. Trop. 56 (3): 995-1001. Epub 2008 September 30
