It becomes detectable in the early days of fever and fades as the body mounts its own response, so the test is most informative in roughly the first five to seven days. After that, the antibodies IgM and then IgG are the better evidence. ## Positive, Negative, and What Each Does Not Mean A positive result points to current dengue infection and should be shown to a doctor on the same day. A negative result is not the end of the question. It can be negative when the fever is several days old, when the virus level is low, or in a repeat infection, where the test detects fewer cases than in a first infection. Persistent fever usually leads doctors to repeat the test or add dengue IgM and IgG. ## Households With More Than One Generation Many homes in Delhi have an elderly parent, working adults and school-age children living together, and a fever in any of them raises questions for all. Dengue can be more worrying in the very young and the elderly, so early confirmation tells the family how closely to watch. Home collection means nobody has to travel while unwell, and one visit can often cover more than one family member if several are unwell. ## Following the Blood Count Doctors follow the Platelet Count over several days in dengue, because a falling trend guides care. The Complete Blood Count (CBC) + ESR is a separate test that can be added. Dengue and malaria are endemic across Delhi NCR, and cases generally rise after the monsoon. ## Warning Signs Do not wait for a report if there is severe abdominal pain, persistent vomiting, bleeding from the gums or nose, black stools, extreme drowsiness or restlessness, or cold clammy skin as the fever settles; go to a hospital. Doctors generally advise against aspirin and ibuprofen when dengue is suspected, so ask which fever medicine is safe, particularly for older family members who may already take blood-thinning medicines. ## What Is Not Included This is a single test. It does not include Dengue IgM or IgG, a Platelet Count or full blood count, dengue PCR or serotyping, or any malaria, typhoid or chikungunya test. The Dengue Profile-Rapid Dengue IgG, Dengue IgM, Dengue NS1 Ag covers all three dengue markers in one booking and suits a fever that has already lasted several days. A doctor should read every result alongside symptoms. Content last reviewed: October 2026
