Malaria Tests
Malaria Test: Everything You Need To Know
Malaria is a deadly disease affecting millions of people in developing countries. It is caused by a parasite and is transmitted via the bite of Anopheles mosquitoes. It is essential to detect the presence of malaria in a patient in order to ensure early treatment and management. Malaria tests are an important tool for detecting the presence of malaria in a patient. Here, we will discuss the preparation, procedure, types, and risks associated with a malaria test, and why one should be tested for malaria.
Preparation for a Malaria Test
No major preparation is required for a malaria test. The healthcare provider might request that a person fast (not eat any food) for several hours prior to the test. Fasting helps the healthcare provider obtain accurate results in some cases.
Procedure for a Malaria Test
The malaria test usually consists of a blood sample. The blood sample is collected and then sent to a laboratory for testing. The blood sample is examined under a microscope to look for the presence of malaria parasites in the red blood cells. It is important to understand that the results of a single malaria test may not be conclusive. It is possible for a malaria test to show a negative result even if the person has malaria, or the test can show a positive result in a person who does not have malaria. Therefore, the healthcare provider may order another test to confirm the results.
Types of Malaria Tests
There are three types of malaria tests:
- Thick blood smears: This is the most common malaria test. A drop of blood is taken from the patient’s fingertip or arm and examined under a microscope for the presence of malaria parasites.
- Rapid diagnostic tests (RDTs): These tests provide results in about 15 minutes and can help diagnose malaria quickly and accurately. They are especially useful in remote locations where a microscope or laboratory is not available.
- Antigen detection tests: This test is used to detect the presence of antigens (proteins) found on the surface of malaria parasites. This test is more accurate than the thick blood smear and the RDT but is more expensive.
Risks Associated with a Malaria Test
There are no major risks associated with a malaria test. A malaria test is a simple procedure and is generally safe and painless. Rarely, some people may experience minor bruising or swelling at the site from where the blood was drawn.
Why and When Should You Get Tested for Malaria?
If you have recently travelled to an area that is known to be highly endemic for malaria, you should be tested for the disease. Symptoms such as fever, chills, nausea, body aches, and headaches, should also prompt a doctor to test for malaria. It is essential to get tested for malaria as early diagnosis can help prevent serious complications or even death.
