To detect the presence of the dengue virus in the blood, you need to undergo definitive tests which include non-structural protein 1 (NS1) test, Immunoglobulin G/ Immunoglobulin M test or a real time polymerase chain reaction (RT-PCR) test.
Similarly one may ask, what is the test for dengue?
Two primary types of testing are available: Molecular testing (polymerase chain reaction, PCR)—this type of test detects the genetic material of the dengue virus in blood within the first week after symptoms appear (fever) and can be used to determine which of the 4 serotypes is causing the infection.
Likewise, how do you know if you have dengue fever? The most common symptom of dengue is fever with any of the following:
- Nausea, vomiting.
- Rash.
- Aches and pains (eye pain, typically behind the eyes, muscle, joint, or bone pain)
- Any warning sign.
Also to know is, when should I get tested for dengue?
This is a blood test to detect the dengue virus early in the course of an infection. When to get the test done: It should be done within the first five days of the appearance of symptoms because after five-seven days, the chances of false positive and negative results are high.
How do you rule out dengue?
For patients presenting during the first week after fever onset, diagnostic testing should include a test for dengue virus (rRT-PCR or NS1) and IgM. For patients presenting >1 week after fever onset, IgM detection is most useful, although NS1 has been reported positive up to 12 days after fever onset (Figure 3-01).
