Malaria presents a diagnostic challenge in most countries. According to the World Malaria Report 2013, an estimated 3.4 billion people are at risk of malaria, of which 1.2 billion are at high risk. Early and accurate diagnosis of malaria is imperative for effective disease management, malaria surveillance, and to prevent the further spread of infection in the community.
The World Health Organization (WHO) recommends prompt malaria diagnosis either by microscopy or malaria rapid diagnostic test (RDT) in all patients with suspected malaria before treatment is administered. Though a valuable technique when done properly, Giemsa malaria microscopy is a time consuming and labor intensive process that requires skilled lab technicians.
On the other hand, rapid diagnostic tests allow for the detection of the parasites within minutes. In malaria-endemic regions, using RDTs is very helpful for the successful use of anti-malarial drugs, as treatment is based on parasite diagnosis and not just fever alone. Research has also indicated the usefulness of RDTs. According to the study published in the Asian Pacific Journal of Tropical Biomedicine which compared rapid RDTs and microscopy in the diagnosis of malaria, RDTs based on malaria antigen method is as precise as traditional microscopy and even appears more sensitive than microscopy.
While there are many brands of malaria test kits in the market, the one from QBC Diagnostics is highly recommended for rapid malaria detection in centrifuged capillary venous blood. Approved by the FDA, this test kit has a long history of proven success in dozens of scientific studies. Up to 5.5 to 7 times more sensitive than traditional Giemsa thick films, the QBC Test also offers equivalent specificity with a negative predictive value of greater than 98%. With a unique, patented combination of technological advances, the test delivers unmatched benefits.
The QBC Malaria Test system uses QBC capillary tube technology to quickly detect malaria. Features and benefits include increased specificity, greater sensitivity, reduced training times, and simple set-up and review. It’s easy to use – simply fill the tube with a patient sample, centrifuge, and place under a fluorescent microscope for review.
