How long does dengue NS1 stay positive?

Dengue NS1 antigen is usually detectable from the first day of fever and remains positive for about 5 to 9 days, often highest in the first 3 to 5 days. In some cases it can persist up to around 12 days. Sensitivity is lower in secondary infections, so a negative NS1 after day 5 does not rule out dengue; PCR or IgM testing may be needed.

What is the cost of NS test?

Which "NS test" do you mean? Common possibilities: non‑stress test (NST) in pregnancy, nucleic acid/PCR (sometimes called NA/NS) tests for infections, or newborn screening (NBS).

Dengue NS 1Antigen, in Gurugram

Q: What is the difference between dengue NS1 and IgM?

NS1 is a dengue viral antigen detectable very early (often days 0–5, sometimes up to day 9), indicating active viremia and acute infection. IgM is the host’s antibody that appears later (typically ~3–5 days after symptoms), peaks around two weeks, and can persist for weeks to months, signaling recent infection. Using both tests broadens diagnostic sensitivity across the illness timeline.

What is Dengue NS 1Antigen?

The Dengue NS1 antigen test detects a protein made by the dengue virus early in infection. It measures the NS1 viral antigen in the blood. Accurate organism identification is clinically essential , typhoid, dengue, and malaria each require different treatment, and the wrong empirical approach delays recovery.

What does Dengue NS 1Antigen measure?

This antigen appears soon after a person is infected, before antibodies develop. Finding NS1 helps doctors confirm dengue fever and identify patients at risk of severe illness. Physicians use it with symptoms, blood counts, and antibody tests to make a diagnosis. Early detection guides monitoring, fluid management, and decisions about hospital care.

What symptoms suggest Dengue NS 1Antigen may be needed?

A doctor may recommend Dengue NS 1Antigen when a patient reports sudden fever (above 38.5°C), body aches and chills, persistent headache, nausea or vomiting, abdominal pain, skin rash, joint pain, and extreme fatigue.

Why Take a Dengue NS 1Antigen Test in Gurugram ?

When does a doctor order Dengue NS 1Antigen?

The Dengue NS1 antigen is often part of an acute dengue panel along with IgM/IgG antibody tests. Doctors order it for sudden high fever, severe headache, rash, joint pain, or bleeding signs.

Who should get Dengue NS 1Antigen done in Gurugram?

Gurugram faces monsoon flooding along the Delhi-NCR belt, with waterlogging on Sohna Road, in Udyog Vihar, and older sectors driving post-monsoon dengue and typhoid. Severe winter air pollution also raises respiratory-infection susceptibility. Dengue NS 1Antigen testing is important for symptomatic patients, for confirming recovery, and for household members of a confirmed case. Testing early in Gurugram's fever season prevents the complications that come from treating the wrong infection.

What conditions can Dengue NS 1Antigen help diagnose?

It helps confirm dengue infection and assess risk of severe disease. Abnormal (positive) results are caused by active dengue virus. Recent travel to endemic areas or exposure during outbreaks increases the need for testing.

What do Dengue NS 1Antigen results mean?

Higher or positive results: Dengue NS1 antigen positive means the dengue virus is present and you likely have an acute (early) dengue infection. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.

How often should Dengue NS 1Antigen be repeated?

Infection tests are ordered when symptoms are present rather than on a fixed schedule. Repeat testing may be needed to confirm recovery, to check clearance after treatment, or if fever recurs. During Gurugram's monsoon fever season, prompt retesting is advised for any new febrile illness.

What happens after Dengue NS 1Antigen results are ready?

Reports arrive digitally and remain in your GetVisit history, so repeat tests can be tracked over months and years. Review anything unexpected with your doctor before changing medication or lifestyle, and use the app to book a follow-up if needed.

What does dengue NS1 antigen positive mean?

Dengue NS1 antigen positive means the dengue virus is present and you likely have an acute (early) dengue infection. NS1 is a viral protein detectable in blood during the first days (usually up to about a week) of illness. A positive NS1 confirms infection but does not predict severity; follow-up tests (IgM/IgG, PCR), platelet and hematocrit monitoring, and clinical observation for warning signs are recommended.

How do you treat dengue NS1 antigen positive?

NS1 antigen–positive means early dengue. Management is supportive: rest, oral fluids/oral rehydration, paracetamol for fever (avoid NSAIDs/aspirin), antiemetics if needed. Monitor daily with clinical checks and blood counts (platelets, hematocrit), and watch for warning signs, severe abdominal pain, persistent vomiting, bleeding, dizziness, reduced urine output. Seek urgent hospital care for warning signs, rapidly falling platelets, or shock.

What is the normal range for dengue NS1 antigen?

The normal (negative) result for dengue NS1 antigen is "not detected" , i.e. below the assay-specific cut-off. Many commercial assays use a cut-off index of <1.0 to indicate negative; quantitative units and reference ranges (e.g. COI or ng/mL) vary by kit and laboratory. Values at or above the manufacturer’s cut-off are reported as positive, indicating acute dengue infection.

What is the difference between dengue NS1 and IgM?

NS1 is a dengue viral antigen detectable very early (often days 0–5, sometimes up to day 9), indicating active viremia and acute infection. IgM is the host’s antibody that appears later (typically ~3–5 days after symptoms), peaks around two weeks, and can persist for weeks to months, signaling recent infection. Using both tests broadens diagnostic sensitivity across the illness timeline.

Can I drink coffee or tea before Dengue NS 1Antigen?

If Dengue NS 1Antigen needs fasting, avoid tea and coffee (even without sugar) during the fasting window, as they can affect some results; plain water is fine. If no fasting is required, your usual drinks are okay.

Can menstruation affect Dengue NS 1Antigen results?

Some tests, such as iron studies and certain hormone panels, can be influenced by your menstrual cycle. If you are on your period, mention it so your doctor can judge whether timing matters for Dengue NS 1Antigen.
