NS1 Test for Dengue: Purpose, Procedure, Normal Range and Cost

NS1 is a test for immunoglobin antigen. Our immune system picks up on new antigens as they enter the body and mimics their characteristics to get ready for any potential future attacks. Therefore, the Dengue NS1 test is quite helpful in identifying and diagnosing dengue. You can get the dengue test in Hyderabad done with a quick online search for the ‘best diagnostic center near me’ and choose a modern and trustworthy diagnostic service provider.

In tropical and subtropical nations, the dengue virus is a frequent cause of sickness. According to statistics, dengue affects over 390 million individuals each year. An individual may develop dengue fever from the mosquito-borne virus, which can then progress to the more severe dengue hemorrhagic fever that results in plasma leakage.

This fever may result in a shock syndrome, which in elderly and pediatric patients may be fatal. In addition, any dengue virus serotypes (DENV 1 to 4) typically spread by the female mosquito species Aedesaegypti can cause the infection.

Dengue NS1 Test

A conserved glycoprotein called NS1 is released by the dengue virus and enters the blood of infected people. Therefore, a significant amount of this protein is present in the patient’s blood serum during the early clinical stage of the illness. The relationship between the NS1 protein and the dengue virus has led to the formation of this new diagnostic tool, and It helped with the quick and accurate diagnosis of dengue.

Doctors frequently use the NS1 test since it is readily accessible and may be performed for the least amount of money. In addition, the test can be performed as soon as 24 hours or seven days after the infection. Antibody tests, such as IgM- and IgG-class antibodies, are frequently carried out to establish solid proof of dengue infection. However, NS1 can be found in the blood before IgM antibodies do.

Purpose of Dengue NS1 Test

If your region has a high rate of dengue infection and your doctor determines that your early symptoms are consistent with normal dengue fever, a test must be performed. This is because the virus takes three to seven days to incubate before exhibiting the typical symptoms of dengue fever. The following are the possible symptoms of dengue:

  • Headache
  • High Fever
  • Muscle, bone, or joint pain
  • Nausea
  • Vomiting
  • Pain behind the eyes
  • Swollen glands
  • Rash

The symptoms can sometimes be mild and mistaken for an ordinary fever or illness. But unfortunately, this may result in liver enlargement, lymphatic and blood vessels harm, and finally, circulatory system collapse.

An early laboratory test for virus detection is crucial for therapy because the symptoms of the illness are non-specific. For example, a person is more susceptible to the disease if they have a weakened immune system or are dealing with a second infection. You can get the dengue test in Hyderabad done with a quick online search for the best diagnostic center.

Most people recover better in about a week. However, in some situations, symptoms might get worse and even be fatal. This condition is called severe dengue, dengue hemorrhagic fever, or dengue shock syndrome. The symptoms of severe dengue are:

  • Acute stomach pain
  • vomiting
  • Bleeding under the skin
  • Difficult or rapid breathing
  • Bleeding from your gums or nose
  • Blood in your urine, stools, or vomit
  • Fatigue
  • Irritability or restlessness

Your blood vessels become damaged and leaky with severe dengue. Additionally, the quantity of platelets in your blood decreases. This could lead to shock, internal bleeding, organ failure, and even death.

The Procedure of Dengue NS1 Test

The dengue NS1 test requires no preparation and fasting beforehand. First, a sample of blood is drawn from the easily accessible arm. Then, to easily observe the vein beneath it, the upper portion of the arm is looped around a belt. Once the vein is visible, the phlebotomist cleans the region with an alcohol pad. Then, the syringe is unwrapped in front of the patient, and blood is collected into the syringe tube. After the blood draw, the belt is loosened to allow the blood to flow back into the body naturally.

The patient is then asked to maintain his arm folded in a perpendicular position for a few minutes while the pierced area is appropriately massaged and wiped with a cotton ball. The blood sample is then transported to a research laboratory for analysis. Cerebrospinal fluid testing is advised if an additional infection caused by meningitis or encephalitis is suspected.

What is the Normal Range of the NS1 Test?

IgG levels should be between 620 and 1400 mg/dl. You might have recently contracted dengue fever if the initial blood sample yields a positive result. Conversely, the test’s negative outcome indicates that the patient is not dengue-infected.

What is the cost of the Dengue NS1 Test in Hyderabad?

The Dengue NS1 test price in Hyderabad is around 1000 INR.

The Final Word

Eliminating mosquito breeding areas, such as open water sources, can help prevent dengue. Another efficient way to avoid contracting dengue is to protect yourself from mosquito bites. Wearing fully-covering clothing and using cream or patches with insect repellent will help you achieve this. The NS1 antigen test is the most effective for the early diagnosis of dengue infection. If you suspect and have any symptoms, wait less and choose the best diagnostic center near you for quick and reliable results.
