Dengue RNA PCR, Qualitative
What is Dengue RNA PCR, Qualitative?
Dengue RNA PCR, Qual test is performed to diagnose dengue fever. It detects the presence of genetic material of the dengue virus in the blood sample. This test is prescribed by the doctor when symptoms of dengue appear like sudden onset of high fever, joint pains, severe headaches, bleeding from gums or nose, low amount of white blood cells, and when exposed to the dengue virus is suspected, for example during an outbreak.
Dengue fever is characterized in two phases acute and convalescent. The initial muscle pain and fever symptoms fall in an acute phase which lasts for 4-5 days. Once the fever subsides the convalescent phase begins. Dengue virus level is higher in blood during the first phase and, therefore, a real-time PCR test is carried out to detect this virus so that it can be treated in its initial stages itself.
Why is Dengue RNA PCR, Qualitative done?
- When symptoms of dengue appear like sudden onset of high fever, joint pains, severe headaches, bleeding from gums or nose, low amount of white blood cells, etc.
- When exposure to the dengue virus is suspected, for example during an outbreak
What does Dengue RNA PCR, Qualitative Measure?
Dengue RT-PCR test is used for the diagnosis of dengue in serum or plasma collected from patients. This test is carried out in patients suffering from the signs and symptoms consistent with dengue (mild or severe) such as fever or chills during the acute phase.
-For the identification of dengue virus serotypes from viral RNA, serum or plasma is collected from people suffering from dengue during the acute phase;
-Dengue test is also carried out to provide information for surveillance of circulating dengue viruses in a population.
