Test Range Values:
Varies based on the specific test kit used and the presence of the antigen.
What is the test?
This test detects the NS1 antigen, a protein produced by the dengue virus, aiding in the early diagnosis of dengue fever.
Test Procedure:
A blood sample is collected and analyzed in the laboratory to detect the presence of the NS1 antigen.
When to take the test:
Particularly useful within the first few days of dengue fever symptoms onset to aid in early diagnosis.
Who should take the test:
Individuals suspected of having dengue fever, especially in regions where the disease is prevalent.
Frequently Asked Questions (FAQs) for NS1 Antigen:
Q1: How soon after dengue fever symptoms start should the NS1 antigen test be taken?
A: The test is most reliable within the first few days (up to about a week) after the onset of symptoms, when the virus is actively replicating.
Q2; Can the NS1 antigen test differentiate between different strains of the dengue virus?
A: No, this test detects the NS1 protein present in all strains of the dengue virus, aiding in the general diagnosis of dengue fever.
Q3: Are there any other conditions or infections that might lead to a false positive NS1 antigen test?
A: In some cases, related flaviviruses or certain cross-reacting proteins might cause false positive results. To be sure, more testing might be necessary.
Q4: Is the NS1 antigen test useful for monitoring the progression or severity of dengue fever?
A: While it aids in early diagnosis, it’s not typically used to monitor the progression or severity of the disease. Other tests may be employed for that purpose.
Q5: Can the NS1 antigen test be used as a standalone diagnostic test for dengue fever?
A: It’s one of the tests used in conjunction with clinical evaluation and other laboratory tests for diagnosing dengue fever, not usually used in isolation.
