Gazelle Diagnostic Device

The 3.5 kg portable device operates on the Magneto-Optical Detector (MOD) which works by detecting a  byproduct of malaria infection in a drop of blood.  When malaria parasites consume red blood cells, they create paramagnetic iron-containing crystals called hemozoin inside red blood cells as shown below. The magneto-optical sensors in the reader measure hemozoin levels. In the case of sickle cell, the reader uses microchip electrophoresis to identify and quantify hemoglobin levels in a blood sample inserted into a cartridge that goes directly into the reader. The device is designed with an in-built battery that can be recharged to run the whole day using an android phone charger. The device can run about 35 to 40 samples a day.

Mechanism of hemozoin detection by MOD

Gazelle has a CE Mark and regulatory approval in India and Ghana after its sickle cell disease test with other registrations pending. The Gazelle Malaria test outperformed Rapid Diagnostic Tests (RDTs) in sensitivity tests in detecting Plasmodium vivax (P. vivax) malaria.

Users are advised to be careful when handling patient blood samples. ^{Interview with representative}
