What are malaria tests?

Plasmodium parasite is the main cause of this deadly disease called malaria. These parasites are nothing but tiny plants or animals that gather energy by using other creatures. It then gets transmitted to humans by the mosquito (Anopheles mosquitoes) when they bite us. 

Malaria is not a contagious disease like the flu, but still it can be spread from one individual to another by mosquitos. Because if a mosquito bites an infected person, it will automatically spread the parasite to anyone else to someone else to whom the mosquito bites. This parasite travels into your bloodstream and starts to increase when it reaches RBC and makes you ill. A malaria test is designed to look for symptoms and signs of malaria infection in the patient’s blood.
