I recently did an NS1 dengue test, which came out negative. Unsatisfied with the result, I repeated the test at a different clinic, and it showed a Dengue NS1 Antigen ratio of 3.5. All other parameters, such as platelet count and blood pressure, are normal. Can someone explain what this result means in detail, and what steps I should take next?

NS1 ratio 3.5 is positive for dengue. Early negatives are common. Rest, hydrate, and monitor fever. Track platelets daily.
