A man came to my clinic with complains of high fever (39 - 41 C) at night and shivering. After the high fever, he is sweating a lot and afterward he felt better. In addition to that, he also suffering with malaise, joint pain, and severe headache. He told me he just came back from Tropical jungle area where Malaria is prevalent.

i check him for enlarged liver and spleen plus jaundice and its positive. So i have concluded its malaria. However, the problem is laboratory blood check result show negative for malaria or dengue fever.

Why the lab result show it negative?

Expertise of the reading the blood film or the lifecycle of the plasmodium species. At my hospital, we order both the thick and thin smears. May help with the expertise issue.

And if we have negative smears initially, we'd repeat them every 4-6 hours. Helps with the lifecycle issue.

Interesting case. Keep us posted.

Ensure the smear was done properly. If the patient is severely anemic locating parasites, fixing, and staining can all be compromised.

Interesting. I also think is necessary to repeat the smear test. Did he have symptoms of bleeding? ( In order to exclude yellow fever)

oroya fever?
