Question 1

Purpose Test

Accepted Answer

Initial rapid screening and early detection: For detecting Dengue virus infection in endemic areas or during disease outbreaks. Distinguishing between acute and previous infection: Helps differentiate between acute (active) infection and previous infection based on antibody patterns (IgM vs. IgG). Primary clinical management: Provides a rapid result to guide initial clinical management, especially in cases showing symptoms of Dengue fever (fever, muscle pain, rash). Epidemiological surveys: Used in rapid epidemiological surveys to assess the spread of infection in a community.

Question 2

Recommended groups

Accepted Answer

Individuals with acute fever symptoms: In areas known for Dengue virus spread (Asia, Latin America, Africa, etc.). Travelers returning from endemic areas: With fever symptoms appearing within two weeks of their return. Patients during Dengue outbreaks: Local outbreaks or epidemics. Patients suspected of having Dengue Hemorrhagic Fever (DHF): Or Dengue Shock Syndrome (DSS).

Question 3

Symptoms indicative

Accepted Answer

Sudden high fever: Which may reach up to 40°C and lasts from 2 to 7 days. Severe pain: Behind the eyes, in the muscles, and joints. Rash. Mild bleeding: Such as gum bleeding, nosebleeds, and red spots under the skin. Nausea and vomiting.

Question 4

Frequently Asked Questions (FAQs)

Accepted Answer

IgM antibodies: They begin to appear 3-5 days after the onset of symptoms, peak at around two weeks, then start to decline and disappear after 2-3 months. IgG antibodies: They appear after IgM and remain in the blood for many years, possibly for life. IgM positive, IgG negative: Indicates a possible acute primary infection. IgM positive, IgG positive: May indicate an acute infection (primary or secondary) or a later stage of primary infection. IgM negative, IgG positive: Indicates a past dengue infection. Both negative: No evidence of current or past infection (or the test may have been too early).

Question 5

Normal Levels

Accepted Answer

The negative (normal) result means there are no detectable IgG and IgM antibodies against the dengue virus in the blood sample taken, indicating no current or past infection (at the time of testing).
