Home collection: Available across Greater Noida; any charge is shown at booking. Lab: NABL-accredited. ## A Test That Depends on the Day The dengue virus releases a protein called NS1 into the blood during active infection. It is detectable from the early days of fever and fades as the immune system responds, which makes this test most informative in roughly the first five to seven days. Later in the illness, antibodies — IgM first, then IgG — are the better evidence. So the day you take the test matters almost as much as the test. ## Reading a Positive and a Negative A positive result points to current dengue infection and should be shown to a doctor on the same day. A negative result is not a clean exclusion. It can be negative when the fever is already 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. If symptoms carry on, doctors usually repeat the test or add dengue IgM and IgG. ## Why Access Matters More Here Greater Noida is spread out. Residential sectors, university areas, societies on Greater Noida West and industrial zones can sit a long way from the nearest collection centre, and a feverish adult or a child is not well placed to make that trip. Home collection turns a half-day errand into a single visit at your door. Because this test needs no fasting or preparation, nothing has to be arranged beforehand, and the earlier the sample is taken, the more reliable the answer. ## Follow the Blood Count, Not Only the Virus In dengue, doctors track the Platelet Count over several days, since a falling trend is what guides care. The Complete Blood Count (CBC) + ESR is a separate test that can be booked alongside this one. Dengue and malaria are both endemic across Delhi NCR, with cases usually rising 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. ## What Is Not Included This is one 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. Any result should be read by a doctor alongside symptoms. Content last reviewed: October 2026
