About this test
The Dengue NS1 Antigen test detects NS1, a protein released by the dengue virus, in your blood. It can confirm dengue early, often from the first day of fever, before your body has made antibodies. It works best in the first 5 days of fever.
Preparation & sample
No special preparation required. Tell us which day of fever you are on, as the test works best in the first 5 days.
What does this test measure?
It looks for the NS1 antigen, a protein the dengue virus releases into the blood while it is multiplying. NS1 is usually present from the first day of fever until around day 5 to 7. This test gives a positive or negative result.
When should you get this test?
- Sudden high fever, especially during the monsoon and post-monsoon season
- Severe headache, pain behind the eyes, or body and joint pain
- Rash, nausea or vomiting with fever
- If someone in your home or area has dengue
- Ideally within the first 5 days of fever
Understanding your results
- Positive: dengue infection is very likely. Your doctor will usually check a CBC every day or two to watch your platelet count and haematocrit.
- Negative: dengue is less likely, but not ruled out, especially if the test was done after day 5 of fever or if this is a repeat dengue infection. Your doctor may advise a Dengue IgM antibody test.
Go to a hospital straight away if you notice severe stomach pain, repeated vomiting, bleeding from the gums or nose, black stools, extreme tiredness or restlessness, or difficulty breathing, especially as the fever comes down.
Avoid painkillers such as aspirin and ibuprofen if dengue is suspected, as they can increase the risk of bleeding. Take only the medicines your doctor advises.
