Dengue NS1 Antigen Detection – Rapid Card

Dengue is a mosquito-borne viral infection transmitted by Aedes mosquitoes. The NS1 antigen is a protein released by the virus during the early stage of infection. The rapid card test detects this antigen in the blood, allowing quick and reliable diagnosis even before antibodies develop. Early detection helps in timely treatment and prevention of complications.

• Detect early-stage dengue infection (Day 1–5 of fever)
