Test: Dengue NS1 Antigen (Rapid). Result: Positive or negative. Price: From 600. Fasting: Not required. Sample: Blood (serum). Reports: Within 12 hours, digital. Home collection: Available across Gurgaon; any charge is shown at booking. Lab: NABL-accredited. ## What NS1 Is, and Why Timing Matters NS1 is a protein made by the dengue virus and released into the blood while the infection is active. It is detectable from the early days of fever and declines as the immune system responds, so this test is most informative in roughly the first five to seven days. Beyond that, antibodies — IgM first, then IgG — carry the diagnostic weight. The most common mistake with dengue testing is taking it too late, not choosing the wrong test. ## Interpreting the Result A positive result indicates current dengue infection and should go to a doctor the same day. A negative result needs care: it does not rule dengue out if the fever is more than a few days old, if the virus level is low, or in a repeat infection, where the test picks up fewer cases than in a first infection. If the fever persists, doctors commonly repeat the test or add dengue IgM and IgG instead of relying on one negative. ## Platelets Are Followed Separately Confirming the virus is only half of managing dengue. Doctors follow the blood count, and a falling Platelet Count is the figure they watch, with serial counts over several days more telling than one. The Complete Blood Count (CBC) + ESR is a separate test that can be booked with this one. Dengue and malaria are endemic across Delhi NCR, and cases usually rise after the monsoon. ## When You Cannot Take a Morning Off Most of Gurgaon's working week happens in offices around DLF Cyber City, Udyog Vihar, Golf Course Road and Sohna Road, and a fever tends to get treated with a tablet and another day at the desk. This test needs no fasting and no preparation, so a phlebotomist can collect the sample at home after work, which keeps the test inside the window in which it is reliable. Do not wait for a convenient Saturday if the fever began on a Monday. ## Warning Signs Go to a hospital without waiting 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. Doctors generally advise against aspirin and ibuprofen when dengue is suspected; ask which fever medicine is safe. ## 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 fits a fever that is already several days old. Results should always be read by a doctor alongside symptoms. Content last reviewed: October 2026
