Recurrent fever can be a frustrating experience, especially when it improves and then returns. One possible cause is malaria. However, there are other infections and medical conditions that may cause fevers to come and go. If malaria is suspected, testing is important to confirm the infection; symptoms alone do not confirm malaria.
Why Should We Test For Malaria In Recurrent Fever?
Malaria is caused by parasites that infect red blood cells. There may be fever, chills, sweating, headache, weakness and muscle aches. These symptoms may resemble dengue, typhoid and other infections.
A doctor may decide to test you for malaria depending on your symptoms, travel or residence in a malaria-endemic area, exposure to mosquitoes, past illness, and examination findings.
Crucial Tests For Detecting Malaria
Blood Peripheral Smear
Malaria is often diagnosed by looking at a peripheral blood smear. A small bit of blood is looked at under a microscope to see if malaria parasites are inside red blood cells. It can also help identify the type of malaria parasite and estimate the degree of infection.
Rapid Diagnostic Tests – RDTs
Rapid diagnostic tests for malaria identify specific parasite proteins in a blood sample. They can give results faster than microscopy and are useful when microscopy at the laboratory is not immediately available. But how accurate they are depends on what test is used and how many parasites are present.
PCR or Molecular Testing
PCR and other molecular tests look for the parasite’s DNA. These tests may be considered in selected situations, such as when the diagnosis is uncertain or more detailed laboratory confirmation is needed. They are not always necessary for routine testing.
What Happens If The First Test Is Negative?
In the setting of high clinical suspicion, a single negative test does not exclude malaria completely. The amount of parasites in the blood can vary during an infection, and testing at the early or low-parasite stage may impact detection.
If malaria is still suspected, a doctor may recommend repeat blood smears or other tests at appropriate intervals. The decision depends on the symptoms, examination, exposure history, and initial test result.
When Should I Consult A Doctor?
See a doctor if the fever returns again and again, lasts several days, or is associated with chills, sweating, headache, vomiting, unusual weakness, or other worrisome symptoms. Don’t assume a recurring fever is malaria without testing it. Doctors may also check for dengue, typhoid, urinary infections or other causes, based on the circumstances.
If you are in Indore and suffering from recurrent fever or fever of unknown origin, timely medical consultation can help decide the relevant tests. Based on the suspected cause, a doctor may discuss dengue, malaria & typhoid treatment in indore after reviewing the symptoms and test findings.
FAQs
Can malaria be diagnosed using a blood test?
Yes. Blood smear microscopy and rapid diagnostic tests are the commonly used methods for malaria detection. Molecular testing may be considered in selected cases.
When to repeat malaria tests?
If your symptoms and exposure history still suggest malaria, your doctor may recommend repeat testing, based on your clinical situation, even if the initial test is negative.
How is a malaria smear different from a rapid test?
A smear looks under a microscope to find parasites in blood . A rapid test looks for specific parasite proteins . And each has its own strengths and limitations .
“Recurrent fever. What else can be the cause?
Recurrent fever can be due to dengue, typhoid, urinary infections, respiratory infections and other illnesses. A medical assessment helps to determine the likely cause.
