Thrombotic microangiopathy following Russell’s viper (Daboia russelii) envenoming in Sri Lanka: a case report

Routine baseline thalassemia screening involves automated FBC to evaluate red cell indices. This does not detect any abnormality in the heterozygous state of Hb Hofu. Hb Hofu was detected by Hb HPLC but can be overlooked due to a close association with Hb A0. Hence, partner screening of a known carrier, especially with beta thalassaemia trait, should include haemoglobin HPLC with careful interpretation.
