Why do you detect dengue fever?
Dengue fever is a viral infection, which transmitted to people by mosquitoes, who lives in tropical and subtropical climates. When an individual develops a fever within two weeks by traveling to the area where dengue is present, it may be wise to prefer tests for dengue fever. Doing series of diagnostic tests, you can detect dengue fever in earlier stages, otherwise it would fetal. World Health Organization (WHO), reported that with a potentially increasing number of cases and countries affected throughout the world, around 50 to 100 million suspected cases occurred annually.
Symptoms of dengue fever
- Sudden and high fever
- Persistent headaches
- Severe pain behind the eyes
- Severe joint pain
- Pain in the muscles
- Nausea or Vomiting
- Skin rash, which appears two to five days after the onset of fever
- Mild bleeding, like nose bleed, bleeding gums, or easy bruising
List of tests to detect dengue fever
Series of blood testing performed to detect dengue fever virus or antibodies, which are produced in response to dengue infections. Dengue fever testing is also used to determine, if a person having dengue symptoms and recent potential exposure to the disease has been infected. Dengue is very difficult to diagnose without any laboratory tests, because symptoms may initially resemble of other diseases, like malaria. The diagnostic tests includes:
- Molecular tests for dengue virus, PCR method
The Molecular test used to detect the presence of the virus; or these tests can diagnose dengue up to 5 days after the onset of symptoms.
- Antibody tests, such as IgM and IgG
These antibody tests performed by detecting antibodies produced by the immune system, when a person exposed to the virus; like these tests are more effective by performing at least 7-10 days after exposure of dengue.
- Complete blood count (CBC)
Complete blood count performed to identify for low platelet count, typical of the later stages of the illness and to detect the decrease in hemoglobin, hematocrit, and red blood cell (RBC) count, such as evidence of anemia. Later that would occur with blood loss, which associated with severe dengue fever.
- Basic metabolic panel (BMP)
In general, BMP performed to monitor kidney function and to search for evidence of dehydration that occurred with severe illness.
No test preparation required of the tests. In general, a blood sample drawn by inserting a needle into a vein in the arm. No laboratory test can determine, whether the infection will progress to the more severe form or not.
