β-Thalassemia mutations in Western India: outcome of prenatal diagnosis in a hemoglobinopathies project.

Prenatal diagnosis (PND) is one of the most cost effective preventive methods, but it is available only in the large cities of India. Therefore, we initiated a program that offers PND and allows us to determine the prevalence of various mutations. Pregnant females (n = 111,426) were screened for hemoglobinopathies using complete blood count (CBC) and high performance liquid chromatography (HPLC).
