Ideally, one needs a battery of tests including detailed peripheral blood picture, Hb A2 estimation, serum iron, Total Iron Binding Capacity (TIBC), serum ferritin and transferrin saturation to differentiate IDA from ssTT clearly.
HPLC has the advantage of quantifying Hb F and Hb A2 along with detecting other variants in a single screening test.

High Hb A2 and F accounted for the common Hb variants in the present study and these findings are similar to the study done in Southern Taiwan21.
Serum iron, total iron binding capacity, ferritin, hemosiderin, ferrokinetics and free erythrocyte protophorin are among further tests that could be done to assess and treat cases of lead poisoning in children in addition to bone marrow tests, such as: stainable iron stores, erythrocyte cellularity, sideroblast % and hemoglobin electrophoresis for Hb A2 and Hb F which increases during lead poisoning.
Hb A2 and Hb F fractions were measured by High Performance Liquid Chromatography using BioRad.
9 was used and same was used for Hb A2 quantitation.
1-3 Routine diagnostic modalities for identification of b thalassaemia include low red cell values (MCV, MCH, RDW) on complete blood picture (CP), altered erythrocyte morphology and increased Hb A2 levels on high performance liquid chromatography (HPLC) or Hb electrophoresis.
Fetal hemoglobin (Hb F) is replaced by Hb A([alpha]2[beta]2) and Hb A2 (a2[delta]2) during the first six to 12 months of life.
