What if dengue ns1 antigen is positive?

Positive: The presence of dengue nonstructural protein 1 (NS1) antigen is consistent with acute-phase infection with dengue virus. The NS1 antigen may be negative if specimen is collected immediately following dengue virus infection (<24-48 hours) and is rarely detectable following 9 to 10 days of symptoms.

.

Just so, what does ns1 positive mean?

A positive NS1 test result confirms dengue virus infection without providing serotype information. A negative NS1 test result does not rule out infection. People with negative NS1 results should be tested for the presence of dengue IgM antibodies to determine possible recent dengue exposure.

Also Know, how do you treat dengue ns1 positive? Treatment for Dengue Fever There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor.

Positive IgM and IgG tests for dengue antibodies detected in an initial blood sample mean that it is likely that the person became infected with dengue virus within recent weeks. If the IgG is positive but the IgM is low or negative, then it is likely that the person had an infection sometime in the past.

Is Dengue ns1 accurate?

The accuracy of the NS1 antigen rapid test is considered high with sensitivity 55%-82% and specificity 97%-100%. Since the NS1 rapid test aims to detect dengue NS1 antigen, it should be performed within 5 days of onset of fever.

How much platelet count is normal in dengue?

The normal count of platelets is 1.5 lakh to 4.5 lakh per microlitre of blood. In viral fever, it reduces up to 90,000 to one lakh. In dengue, this count goes down to 20,000 or even lower, but reaches the normal once dengue is cured. In a viral fever this count comes to the normal range gradually.”
