When does a doctor order Dengue NS 1Antigen?

Who should get Dengue NS 1Antigen done in Kolkata?

Kolkata's June-to-October monsoon season brings sharp spikes in dengue, typhoid, malaria, and leptospirosis , particularly in flood-prone areas such as Behala, Dum Dum, Howrah, and Ultadanga. Early testing is essential because each condition requires a different treatment approach. The Dengue NS1 antigen is often part of an acute dengue panel along with IgM/IgG antibody tests. Doctors order it for sudden high fever, severe headache, rash, joint pain, or bleeding signs. Those who benefit most from regular Dengue NS 1Antigen testing include adults above 40, people with sedentary lifestyles or BMI above 25, those managing chronic conditions, smokers, and anyone whose previous result was borderline. Early detection through regular testing in Kolkata is consistently more cost-effective than treating advanced disease.

What conditions can Dengue NS 1Antigen help diagnose?

The conditions diagnosable through Dengue NS 1Antigen depend on the specific markers the test measures. Results either confirm a suspected diagnosis, support a clinical suspicion requiring further investigation, or effectively exclude the condition the test was screening for.

What do Dengue NS 1Antigen results mean?

Positive antigen test (dengue NS1, malaria RDT, typhoid Vi antigen): active infection , treatment should begin promptly. Positive antibody IgM: recent or active infection. Positive IgG without IgM: past infection or immunity, not active disease. Widal titre of 1:160 or above for Salmonella typhi H and O antigens supports typhoid diagnosis in a symptomatic patient with no prior typhoid history.

How often should Dengue NS 1Antigen be repeated?

For preventive screening with a normal baseline: annually for most adults above 35. For monitoring a known condition: at the interval your specialist recommends , typically every 3 to 6 months for active conditions and annually for stable, well-controlled ones.
