Dengue Ns1 Antigen Test Interpretation

Here is a normal interpretation of the Dengue Ns1 Antigen Test.

Result	Interpretation
Negative (<0.9 Index)	No detectable dengue NS1 antigen. The result does not rule out dengue infection. An additional sample should be tested for IgG & IgM serology in 7-14 days.
Equivocal (0.9-1.1 Index)	Repeat the sample after 1 week.
Positive (>1.1 Index)	Presence of detectable dengue NS1 antigen. Dengue IgG & IgM serology assays should be performed on follow-up samples after 5-7 days of onset of fever, to confirm dengue infection.

Summary

Positive result Indicates the presence of Dengue virus antigens in the blood, suggesting active infection. Negative result Indicates the absence of Dengue virus antigens in the blood, but does not rule out the possibility of a recent infection
