Gazelle Diagnostic Device
Hemex Health Inc
Gazelle diagnostic device is a non-invasive sickle cell and malaria diagnostic device
Gazelle is a compact, rugged, and portable battery-operated point-of-care test diagnostic device for anemia and sickle cell disease (SCD) with results in just minutes. There are two variants of the device, the Gazelle Hb Variant and the Gazelle malaria. A commercialized tool for anemia is being developed with the goal of a one-minute 25-cent noninvasive diagnostic tool for screening anemia, malaria, and SCD using an optical finger sensor.
The product is distributed by the following institutions: Hemex Health, HemexDx Case Western Reserve University, Novartis Biome,Tata Elxsi, Bio-Rad Laboratories
At the factory, the reader costs between 800 USD and 1,200 USD, while the cartridges range from 1 USD to 3 USD. The cost of the test with the device is about one dollar per test. The price after delivery and shipping can sometimes cost about twice the factory price. Interview with representative
Goal 3: Good health and well-being
The device is manufactured at Robonik India. The cartridges are manufactured at Lakshmi Lifesciences, Coimbatore.
Gazelle is built on the company’s proprietary microchip electrophoresis technology which is patented and trademarked.
The product can be directly ordered from the manufacturer or other distributors like EHACLINICS
As of 2021, 300 Gazelle’s devices have been distributed to date. Interview with representative
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
The technical support is provided by the manufacturer and distributors like EHACLINICS
There are no replacement components for the device. The device is not to be serviced in the field. Interview with representative
5 years Interview with representative
The manufacturer has the following specified targets: lightweight, transportable, battery-powered, designed for most extreme environments, designed with no cold chain requirements, cloud-based storage
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
The Gazelle cloud application stores over 2500 patient reports that can be viewed onscreen or sent to a connected printer. Users can download the reports to a USB drive for transfer to a personal computer.

Gazelle diagnostic device has regulatory approval in Ghana and India. The product also has a CE mark
Sensitivity and specificity testing: A study conducted in the Brazilian Amazon on P. vivax showed that Gazelle was more sensitive than RDTs and comparable in accuracy to expert microscopy, but significantly faster than RDTs, microscopy and PCR as reported by Yahoo! finance
