Dengue NS1 Antigen & Antibodies Test

Dengue Fever Test – Dengue virus NS1 test is used to detect dengue in the early days (1-2 days) of the fever. This test is used to detect dengue nonstructural protein 1 (NS1) antigen in the acute phase infection of dengue virus. This test is also used to detect secondary dengue virus infection in a shorter duration of time within 1-4 days following the onset of symptoms.

What is Dengue?

Dengue fever is a mosquito-borne disease transmitted by Aedes aegypti and Aedes albopictus mosquitoes. These mosquitoes bite during day time hence protection from mosquitoes at night by mosquito repellents and nets does not prevent dengue fever. They breed in fresh and clean water and also in tubes, drums, containers, old tyres, and cans. It is mostly found in tropical and subtropical regions of over 100 countries. The incubation period of dengue virus is 4-10 days. There are three types of dengue fever:

  • Dengue shock syndrome with low blood pressure.
  • Dengue fever with no serious complications.
  • Dengue hemorrhagic fever with bleeding problems or low platelet and plasma leakage.

Accurate and timely detection of the dengue virus is important for the early diagnosis of dengue fever. This test is used especially for the early detection of the dengue virus.

Why dengue ns1 test is performed?

This test may be recommended to you if you are suspected of dengue viral attack. The symptoms include a fall in body temperature, rapid breathing, bleeding gums or bleeding in other regions, severe abdominal pain, headache, pain behind eyes, increased tiredness, rashes, nausea, headache, and joint pains, etc.

Dengue NS1 Test Result Interpretation

If your test results show positive results then the dengue NS1 antigen is consistent with acute-phase infection.

If your test results are negative then the dengue NS1 antigen is consistent with the lack of acute phase infection. The dengue NS1 test may also be negative if the specimen is collected before 24-48 hours of dengue virus attack.

fever, the recommended test is Dengue fever antibodies IgG&IgM by ELISA
