In order to identify a quick and reliable technique for accurate diagnosis of malaria, study of the efficiency of the tests such as Parahit total (HRPII & aldolase Ag), Advantage mal card (parasite specific LDH), and modified QBC was done in comparison with conventional blood smear microscopy. One hundred patients infected withP. vivaxand 101 infected withP. falciparumwere included in this study. The sensitivity of Parahit total, Advantage mal card, and modified QBC forP. falciparumdetection was 70.3, 95%, and 98%, and specificity was 98%, 98%, and 96%, respectively. The sensitivity of Parahit total, Advantage mal card, and modified QBC forP. vivaxdetection was 73%, 97.0%, and 98%, respectively, and specificity of all the tests was 98%. On day 15, in falciparum arm, Advantage mal card and Parahit total showed 8 (7.92%) and 59 (58.41%) false positives. On day 15, in vivax arm, Parahit total revealed 52% false positives. The study indicated that modified QBC could be only used where appropriate facilities are available. Advantage mal card was a better follow-up tool than Parahit total.

Peripheral Blood Eosinophilia

Filariasis is a parasitic infection seen predominantly in tropical and subtropical countries including India. In clinically suspected cases, examining a thick wet mount smear or a buffy coat film is most informative. In unsuspected cases, however, eosinophilia in a peripheral blood smear (PBS) may be the sole indicator of parasitaemia. A few cases of tissue microfilaria with the absence of peripheral blood eosinophilia (PBE) have been reported. Here, we report two cases of microfilaria in PBS in the absence of PBE. A routine screening of the tail end of all PBS at low power magnification is also advised as it may facilitate the detection of asymptomatic cases when there is a normal eosinophil count.
