Dengue Antibody IgG, ELISA Test

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.

Electrolytes like sodium, potassium, and chloride are essential to maintain water and pH balance in the body. 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).
