   May 14, 2024 · Dengue virus RNA can usually be detected by nucleic acid amplification tests (NAAT) for the first 7 days of illness. A positive NAAT (e.g. RT-PCR) result confirms current dengue virus infection. A negative NAAT result does not rule out infection.

   May 14, 2024 · What the test is. NS1 tests detect the non-structural protein 1 (NS1) of dengue virus. This protein is secreted into the blood during a dengue infection. NS1 tests have been developed for use in serum. Most of these tests use synthetically labeled antibodies to detect dengue NS1 protein.

   Can dengue virus RNA be detected by a molecular test?

   • For symptomatic persons with dengue virus infection, dengue virus RNA can usually be detected by molecular tests for the first 1-7 days in the course of illness. What is the test? A NAAT is a generic term referring to molecular tests used to detect viral genomic material.

   How is dengue infection confirmed?

   • Dengue infection was confirmed by an NS1 antigen test or a quantitative PCR (qPCR) which amplified a small segment of the genome as described previously 24, enabling serotyping of the sample.

   Does a single nucleotide polymorphism protect against severe dengue?

   • The genotype of an single nucleotide polymorphism (SNP) at position 352 of the VDR gene was associated with protection from severe dengue ( Loke et al., 2002 ). They also showed that homozygotes for the arginine variant at position 131 of the Fcγ receptor (FcγR) II gene appeared to be protected from the development of severe DENV infection.

   Laboratory Guidance and Diagnostic Testing. Tweet Compartir. Dengue can be diagnosed by isolation of the virus, by serological tests, or by molecular methods. Diagnosis of acute (on-going) or recent dengue infection can be established by testing serum samples during the first 5 days of symptoms and/or early convalescent phase (more than 5 days ...
