Malaria Diagnosis: An Overview
In order to make a
malaria diagnosis, the healthcare provider may ask a number of questions concerning:
- Current symptoms
- Medical conditions
- Family medical history
- Current medications
- Recent travel history.
The healthcare provider will also likely perform a physical exam, looking for signs or symptoms of malaria. He or she may also order certain tests to help in diagnosing malaria or another condition.
Tests Used to Make a Malaria Diagnosis
The doctor may suspect malaria based on the patient's symptoms, and the physical findings at examination; however, to make a definitive diagnosis of malaria, laboratory tests must demonstrate the malaria parasites, or their components.
The best test available to diagnose malaria is called a blood smear. In this test, malaria parasites can be identified by examining a drop of the patient's blood under the microscope, spread out as a "blood smear" on a microscope slide. Prior to examination, the specimen (blood) is stained to give to the parasites a distinctive appearance.
There are other blood tests available that may be used along with a blood smear to confirm a malaria diagnosis.
