blood analysis The physical and chemical properties of a sample of blood are examined during blood analysis. The examination of blood is important for the accurate diagnosis of disease.

Examining red blood cells under a microscope is considered the gold-standard method for diagnosing malaria. This process involves a trained technician preparing a blood smear to identify and distinguish between the specific species of Plasmodium parasites present in the sample.12

Because Plasmodium parasites invade, grow within, and eventually destroy red blood cells, microscopic examination allows clinicians to visualize the parasites directly. This identification is critical because different species, such as the deadly P. falciparum, require specific medical attention to prevent severe complications like cerebral malaria.34

While highly reliable, this diagnostic method requires skilled staff and laboratory facilities. It can also be challenging in cases where parasite density is very low or when distinguishing between similar-looking species, such as P. knowlesi and P. malariae. Prompt and accurate diagnosis is essential, as the disease can progress rapidly and lead to fatal outcomes.23
