Hb HPLC is an important tool in the diagnosis of various haemoglobinopathies. However, in some cases, it has its diagnostic limitations, when used alone and it is judicious to reconfirm by a second independent technique, as per current guidelines [1]. To illustrate this, we are presenting two cases of haemoglobinopathies reported in Haematology Department of a tertiary care hospital.In one case (Case 1), a 24 years old North Indian Punjabi female presented in our Haematology Lab for routine antenatal Hb HPLC referred by Obstetrics and Gynaecology Department her Hb analysis by HPLC demonstrated HbF (0.7 %), HbA 0 (49.8 %) and a variant Hb (43.1 %) in the HbA 2 window with a retention time of 3.62 min (Fig. 1). Her Hb was 11.8 Gm%, RBC indices were normal and blood picture was normocytic normochromic.In another case (Case 2), a 26 years old North Indian Punjabi male, presented for routine Hb HPLC. His Hb analysis by HPLC demonstrated HbF (0.7 %), HbA 0 (49.8 %) and a variant Hb (42.1 %) in the HbA 2 window with a retention time of 3.62 min. His Hb was 15.4 Gm% with normal red cell indices and normocytic normochromic blood picture.The haemoglobins which can elute by HPLC in the HbA 2 window with the retention time range of 3.3-3.9 min are HbA 2

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
