Dengue NS1 Antigen (Rapid) Test in Noida

It detects NS1, a protein released by the dengue virus into the blood during active infection. It is a qualitative test, so the result is positive or negative. NS1 can be detected from the early days of fever, usually up to about day 5 to 7, which is earlier than the antibodies that other dengue tests look for.

It starts from 600 in Noida. Home sample collection is available across the city and any collection charge is shown in the booking flow before you confirm. Digital reports are included. You can book online or on WhatsApp.

As early as possible, ideally within the first five days of fever. NS1 is present at its highest level early and falls as the immune system responds. After about a week, antibody tests — dengue IgM and IgG — are more useful, and a negative NS1 on its own means much less.

No. A negative result does not exclude dengue when the fever is more than a few days old, when the virus level is low, or in a repeat infection, where the test tends to detect fewer cases than in a first infection. If symptoms continue, doctors usually repeat the test or add dengue IgM and IgG. Do not stop medical follow-up because of a single negative result.

NS1 is a viral protein that shows current infection in the early days. IgM is the antibody the body makes first, usually appearing a few days into the illness. IgG is the later antibody, which also rises in a repeat infection and can remain after recovery. NS1 suits early fever; IgM and IgG suit later fever. The Dengue Profile-Rapid Dengue IgG, Dengue IgM, Dengue NS1 Ag tests all three together.

No. The test needs no fasting and no preparation, so the sample can be taken at any time of day. The more useful thing to note is the day your fever began, since the timing affects how the result is read.

Digital reports are issued within 12 hours of sample collection. The result is marked clearly as positive or negative.

It is a rapid immunoassay, and its reliability depends mainly on how many days into the illness the sample is taken. It is more dependable in the first few days and less so later, and it detects fewer cases in a repeat infection. A positive result is strong evidence of dengue; a negative one is not proof of its absence. Your doctor reads it together with your symptoms and blood counts.

Often, yes. Dengue is monitored through the blood count, and a falling Platelet Count is the parameter doctors follow. Serial counts over several days tell more than a single reading. The Platelet Count and the Complete Blood Count (CBC) + ESR are separate tests that can be booked alongside this one.

Yes. A trained phlebotomist can collect the sample at your address across Noida, including Sector 15, 18, 27, 44, 50, 62, 63, 76, 93, 120, 137 and Noida Extension. Any home collection charge is stated in the booking flow before you confirm.

Yes. This test needs no fasting and no preparation, so a sample can be taken at any hour, including straight after a shift. Because early testing makes the result more reliable, it is better to book the same day a fever starts than to wait for a daytime slot.

Dengue cases across Delhi NCR usually begin to rise after the monsoon and are commonly highest from about September to November, though the timing varies from year to year. A fever in this period is a reason to test early instead of treating it as an ordinary viral fever for several days.

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. These can signal severe dengue and should be seen urgently. This page is general information, not medical advice; follow your doctor's instructions.
