Dengue is a viral infection transmitted specifically by the Aedes mosquito. It is important to diagnose dengue accurately because early detection and proper medical care can help prevent complications.
There are two main types of blood tests used to diagnose dengue:
NS1 Antigen Test:
The NS1 (non-structural protein 1) antigen test is a rapid diagnostic test that detects the presence of the NS1 protein, which is produced by the dengue virus early in the infection. This test is usually performed in the first few days of symptom onset and is considered highly specific for dengue. It can be done using a blood sample from a finger prick, making it a quick and convenient method for early detection.
Dengue Antibody Tests (IgM and IgG):
These tests detect the presence of antibodies produced by the immune system in response to the dengue virus. There are two types of antibodies that are tested:
IgM Antibodies: These are produced in the early stages of the infection and can be detected a few days after symptoms start. High levels of IgM antibodies usually indicate a recent or current dengue infection.
IgG Antibodies: These are produced later in the infection and persist for a longer time. High levels of IgG antibodies may suggest a past dengue infection or previous exposure to the virus.
Blood samples for antibody tests are usually collected through venipuncture (a standard blood draw from a vein) and sent to a laboratory for analysis.
It’s important to note that accurate diagnosis of dengue may require a combination of these tests, especially in the early stages of infection. Some healthcare providers might order both the NS1 antigen test and antibody tests for a more comprehensive diagnosis.
Interpreting the results of these tests requires medical expertise. False positives and false negatives can occur, so healthcare professionals consider the patient’s clinical symptoms, travel history, and the timing of the tests in conjunction with the results to make an accurate diagnosis.
If you suspect you have dengue or are experiencing symptoms such as high fever, severe headache, joint and muscle pain, rash, and mild bleeding, it’s essential to seek medical attention. Early diagnosis and proper medical care can significantly improve the outcome for individuals with dengue fever.
