Common questions
When should I take the NS1 test?
It works best in the first 1 to 5 days of fever, when the antigen is most likely to be detected.
What if my NS1 is non-reactive but I still feel sick?
NS1 can become negative as the illness progresses, so antibody testing may be recommended if symptoms continue.
