First read a couple of papers in Malaria. You can easily go through terminology using wikipedia/google. If you don't have a strong background in human pathophysiology it's going to take some time, but given the right amount of time it's not thing really hard. You'll just give the time for some concepts to sink in.
What I'd like to see is an open source version of this machine which can be easily reproduced in pure countries.
HOWEVER, smart as it may seem, if I don't see some triple-checked hard-data, it's hard to tell if the magnets approach actually works and here is were professional clinical trials are made. Because in real life it's extremely hard to take say 5.000 blood samples from people who might be infected (e.g. Africans) right down the results, then go to a professional lab and compare the samples. Write down the results, find in which conditions concentration of 'Fe' is high in blood. Probably talking to the IDI[1] would be a nice first step and so on.
