Late Malaria Confirmation

January 28, 2012 By Malaria Q&A Leave a Comment

QUESTION

I was given a field diagnosis of malaria 1 1/2years ago and was treated. Can I still get a blood test to confirm if I truly had malaria?

ANSWER

That’s a very interesting question, and the answer is: it depends. Since you were treated, you will no longer have the parasites in your blood stream, and so you cannot use a traditional blood film, looked at under a microscrope, which is the standard diagnostic method in many places.

However, there are other blood tests which look for the presence of antibodies against specific malaria proteins. These antibodies can remain in the blood for a long time after the malaria infection – probably months, but perhaps even years, though the exact length of time may vary from person to person, as well as between antibodies. If you wanted, you could inquire in your hospital whether it would be possible to get a serology test for malaria (serology tests look for antibodies) – if they tell you the brand they use then you could also contact the manufacturer to ask if they have done tests on the length of time the antibodies stay in the blood.
