What is a normal NS1 level for dengue?

There is no specific "normal" level for the NS1 antigen in dengue, as its presence or absence is used for diagnostic purposes rather than quantitative measurement. The NS1 antigen test is a qualitative test that detects the presence or absence of the NS1 protein in the blood. A positive NS1 result indicates the presence of the NS1 antigen, suggesting an active dengue infection. It is important to interpret the NS1 test results in conjunction with clinical symptoms, medical history, and other laboratory findings to make a diagnosis and determine appropriate treatment. Consultation with a healthcare professional is necessary for the proper interpretation of NS1 test results and management of dengue.
