Dengue NS1 Antigen Test

Dengue NS1 Antigen Test

What is the Dengue NS1 Antigen test?

The Dengue NS1 Antigen test is used to diagnose dengue fever early. The dengue NS1 antigen, a protein and toxin produced by the dengue virus, is tested for in this test. A technique known as ELISA is used to detect it in the lab (enzyme-linked immunosorbent assay). This protein triggers an immune response in our bodies, causing antibodies to be produced in order to combat the viral infection. As soon as dengue symptoms appear, the NS1 antigen is present in the blood of an infected person. As a result, this test aids in the early detection of dengue fever.


Antibody testing - antibody tests may be reported as positive or negative or may be reported as an antibody titer with an interpretation of which type(s) of antibody (lgG or lgM) is present.

How accurate is the dengue NS1 antigen test in Delhi?

The dengue NS1 antigen test is a useful tool for the early detection of dengue virus infection. In Delhi, where dengue fever is a recurrent health concern, the NS1 antigen test is widely used for diagnosing dengue.

The NS1 antigen test detects the presence of dengue virus antigens in the blood sample of an infected person. It can detect the virus as early as the first day of infection and is useful for diagnosing dengue during the acute phase of the illness.

Studies have shown that the NS1 antigen test has a high sensitivity (ability to detect true positives) and specificity (ability to detect true negatives) in the diagnosis of dengue. In Delhi, a study conducted in 2015 found that the NS1 antigen test had a sensitivity of 86.7% and a specificity of 93.75%.

However, it is important to note that the accuracy of the test may vary depending on various factors such as the timing of the test, the quality of the test kit, and the prevalence of other viral illnesses that may produce false-positive results.

Therefore, it is recommended to confirm the diagnosis of dengue using other tests such as PCR (polymerase chain reaction) or IgM/IgG antibody tests. A combination of these tests can provide a more accurate diagnosis of dengue infection.

In conclusion, the NS1 antigen test is a reliable tool for the early diagnosis of dengue infection, especially during the acute phase of the illness. It has high sensitivity and specificity in Delhi and is widely used by healthcare professionals for diagnosing dengue. However, it is important to keep in mind that the accuracy of the test may vary depending on various factors, and confirmatory tests may be required to provide a more accurate diagnosis.

It is crucial to seek medical attention if you experience symptoms of dengue fever, such as high fever, severe headache, joint and muscle pain, and rash. Early diagnosis and treatment can help prevent complications and reduce the risk of severe illness or death. In addition to diagnostic tests, healthcare professionals may recommend supportive measures such as hydration, rest, and pain relief medications to manage the symptoms of dengue fever. Taking preventive measures such as using mosquito repellents, wearing protective clothing, and eliminating breeding sites of mosquitoes can also help reduce the risk of dengue infection.

Are there any home collection services available for a dengue NS1 antigen test in Delhi?

Yes, there are several home collection services available for a dengue NS1 antigen test in Delhi. With the rise of online healthcare services, many clinics and diagnostic centers now offer doorstep sample collection services for the convenience of patients. These services allow you to get your blood samples collected from the comfort of your home, without having to wait in long queues or travel to a healthcare center.

To avail of these services, you can search for diagnostic centers or clinics in your area that offer home collection services for dengue NS1 antigen tests. You can also use online healthcare platforms and mobile apps to book an appointment for sample collection at home. Once you have booked your appointment, a trained phlebotomist will arrive at your doorstep to collect the blood sample.

It is important to note that while home collection services are convenient, they may come at an additional cost. You should also ensure that the diagnostic center or clinic you choose is accredited and follows recommended safety protocols for sample collection and testing.

In summary, if you are looking for a dengue NS1 antigen test in Delhi and prefer the convenience of getting your blood sample collected at home, you can opt for home collection services offered by various diagnostic centers and clinics in the city.

How long does it take to get the results of a dengue NS1 antigen test in Delhi?

If you suspect that you or someone you know has been infected with the dengue virus, it is important to get tested as soon as possible. One of the most common tests used for dengue fever diagnosis is the NS1 antigen test. This test detects the presence of the dengue virus in the blood within the first few days of illness.

If you are in Delhi, the time it takes to get the results of a dengue NS1 antigen test can vary depending on the lab or healthcare facility where you get tested. Generally, the test results are available within 24-48 hours.

Many private labs and hospitals offer rapid NS1 antigen tests, which can provide results within a few hours. These tests are more expensive than the standard test and may not be covered by all insurance policies.

It is important to note that, although the NS1 antigen test is sensitive and specific, it is not always accurate. False negatives can occur if the test is performed too early in the course of the illness or if the patient has already developed antibodies to the virus. Therefore, it is recommended to confirm the diagnosis with a PCR (polymerase chain reaction) test or an IgM antibody test, which can detect the presence of the virus or antibodies at later stages of the disease.

In conclusion, if you suspect dengue fever, it is important to seek medical attention and get tested as soon as possible. The NS1 antigen test is one of the most commonly used tests for early diagnosis of dengue fever, and it is available at various diagnostic centers and hospitals in Delhi. While home collection services may provide convenience, it is important to ensure that you choose a reliable and accredited facility for testing.

Remember that rapid NS1 antigen tests may offer quicker results, but they can be more expensive and may not be covered by insurance. Additionally, false negatives can occur with the NS1 antigen test, so it is recommended to confirm the diagnosis with a PCR or IgM antibody test. Early diagnosis and prompt treatment are crucial for managing dengue fever and avoiding complications, so don't hesitate to get tested if you suspect you may have been infected.
