Question: If you’ve ever had malaria in the past, can that be detected?
Answer: Often, yes. There are tests which can look for antibodies (proteins that your body produces in response to an infection) that are specific to malaria. Some of these antibodies only last a few weeks or months, but others can persist for years. These tests use enzymes on a sample of your serum and so are usually known as “Enzyme-linked immunosorbent assays” or “ELISAs”. You may be able to ask your medical practitioner if such tests are available where you are.
