Dengue Ns1 Antigen Pcr Blood
What is this test?
Dengue virus NS1 test is used to detect dengue in 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 do 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 dengue virus is important for the early diagnosis of dengue fever. This test is used especially for early detection of dengue virus.
