Dengue Antibody IgG, ELISA Test
Dengue Antibody IgG, ELISA
Mosquitoes that live in tropical and subtropical climates commonly transmit dengue fever to humans. Blood tests like Dengue Antibody IgG, ELISA test can find antibodies made in response to a dengue infection or the dengue virus itself.
Enzyme-linked immunosorbent assay or ELISA is an immunoassay method for qualitative detection of antibodies to dengue in human. The dengue antibody IgG, ELISA test serves as a screening tool and yields an early assessment of any previous or ongoing dengue virus infection. It identifies secondary dengue infections and looks for specific IgG antibodies in the patient’s serum. The antibody levels rise for about 7 days, reaching their peak in the second week. It lasts 90 days in the blood. However, in some individuals, these antibodies may remain in them for the rest of their lives.
Thus, getting the dengue IgG, ELISA test done is recommended for early detection of any secondary dengue infection and for preventing fatal conditions like dengue hemorrhagic fever, dengue shock syndrome, reduced blood cell counts, etc.

Deviation from normal levels indicates the following:
·      A Positive test result for dengue IgG antibodies but not IgM antibodies is usually caused due to  an infection in the past.
·      A recent infection is most likely the case if the dengue IgG antibody test titre increases by fourfold or more between the initial sample and one taken two to four weeks later.
·      IgG and IgM antibody positive tests indicate current dengue virus infection.
A Negative IgG test result indicates no dengue infection
FAQs
How is the sample collected for a Dengue Antibody IgG, ELISA test?
A blood sample is taken from a vein in the arm using a fine needle. This procedure typically takes no longer than five minutes
What are the risks involved in a Dengue Antibody IgG, ELISA test?
This test involves negligible risk. There might be slight pain or tenderness around the site where the needle went in. Rarely, the site can become infected.
What is the turnaround time (TAT) for the result of a Dengue Antibody IgG, ELISA test?
Dengue Antibody IgG, ELISA test result is usually available within the same day the test was taken, although it could take longer at times
What are the limitations of a Dengue Antibody IgG, ELISA test?
False-positive results are possible in people who have other flavivirus infections, such as West Nile virus, St. Louis encephalitis virus, and Zika virus. To identify the infecting virus, additional laboratory testing and obtaining a detailed exposure history is necessary. Also, for people who have received blood transfusions or other blood products within the last several months, positive test results might not be reliable
Can dengue fever be transmitted from person to person?
Person-to-person contact or exposure to respiratory secretions does not spread the virus.
The virus spreads when a mosquito bites an infected person and then bites a healthy person. Rarely, it may be passed from mother to fetus, through organ donation, or through blood transfusions.

Complete blood count (CBC) is a type of blood test that helps determine an individual's overall health. This test evaluates red blood cells that carry oxygen from the lungs to the rest of the body and white blood cells , which fight infections and other diseases. There are five major types of white blood cells, and the CBC test measures the total number of white cells in the blood.CBC test includes an absolute and differential count of basophil, eosinophil, lymphocyte, monocyte, and neutrophil that measures the levels of these cells in the blood. CBC also measures the levels of platelets, which help prevent and stop bleeding. Hemoglobin is a protein in red blood cells, and the Mean corpuscular hemoglobin (MCH) test measures the average amount of hemoglobin in each red blood cell, mean corpuscular hemoglobin concentration (MCHC) test determines the average concentration of hemoglobin in a single red blood cell (RBC). Hematocrit/ Packed Cell Volume (PCV) measures the proportion of red blood cells, and red cell distribution width (RDW) evaluates the differences in the volume and size of your red blood cells. Mean corpuscular volume (MCV) measures the average size of the red blood cells. Complete blood counts can help detect various disorders, including infections, anemia, and diseases affecting blood components.

A serum electrolyte test includes a set of tests that help to identify electrolyte imbalances in the body. Malnutrition is one of the key reason for serum electrolyte panel testing.The serum electrolyte tests are indicated in patients experiencing abnormal heartbeat or muscle weakness. It is also done to evaluate and monitor hypertension and kidney disease conditions.

Dengue antibody IgG, ELISA, also known as the Immunoglobulin G Test, is used to detect dengue virus IgG antibodies. The presence of IgG alone, in the absence of NS1 Ag and/or IgM, does not indicate active dengue infection. This test is frequently used as a screening tool and assesses any past dengue virus infection. The levels of IgG antibodies rise for around seven days, reaching their peak in the second week and lasting for 90 days in the blood. However, in some people, IgG antibodies could stay for a lifetime.

The DENGUE ANTIBODY IgM ELISA test is used for the qualitative detection of dengue virus IgM antibodies. When the immune system defends against infection, IgM antibodies against the dengue virus are detectable in the 4-5 days after the onset of symptoms and are detectable for around 12 weeks. Positive IgM results are classified as possible recent dengue virus infections. Negative IgM results after seven days of symptoms and negative nucleic acid amplification test (NAAT) or NS1 (dengue antigen detection) are considered negative for recent infection.

Dengue fever IgG and IgM antibodies test qualitatively detect IgG and IgM antibodies. This test is frequently used as a screening tool and provides an assessment of any past or present dengue virus infection. Dengue is a virus spread to people through the bite of an infected Aedes mosquito. Our body produces IgG and IgM antibodies when infected with the dengue virus. IgM antibodies against the dengue virus are detectable 4-5 days after the onset of symptoms and are detectable for around 12 weeks. Positive IgM results are classified as possible current dengue virus infections. Dengue IgG antibodies appear roughly at the day 7 of the fever, in the primary infection and continue for a longer time, even up to years. Hence If IgG is positive and IgM is negative, this indicates that the person was infected with dengue in the past.

Dengue NSI antigen-RAPID blood test is carried out to detect dengue NS1 antigen (non-structural 1 protein) in infected individuals. A positive NS1 protein test helps in the early diagnosis of dengue infection caused due to bite of female mosquitoes, mainly Aedes aegypti and Aedes albopictus species. NS1 antigen (protein) can be detected during the first seven days of symptoms. Dengue NS1 antigen serves as a crucial marker of severe clinical disease, and higher levels have been observed with dengue haemorrhagic fever (DHF; very high fever generally 3-7 days after symptoms are seen).
