Rubella or German measles is a contagious viral infection caused by the rubella virus. On exposure to the rubella virus, a person develops pinkish-red rashes, mild fever, swollen lymph nodes, runny nose, headache, and joint pain. Rubella is a droplet infection. Two antibodies whose detection is vital to confirm Rubella infection are – IgM and IgG. The antibodies remain for years in the bloodstream. The Rubella antibody blood test may confirm immunity towards Rubella or detect past or recent Rubella infection. It also confirms whether a person has ever been exposed to the virus or has been vaccinated. The test is done by pregnant women and would-be mothers to confirm immunity towards Rubella infection.
Rubella (commonly known as German measles or 3-day measles) is an infection that primarily affects the skin and lymph nodes. It is caused by the rubella virus (not the same virus that causes measles), which is usually transmitted by secretions from the nose or throat. It can also pass through a pregnant woman's bloodstream to infect her unborn child. As this is a generally mild disease in children, the primary medical danger of rubella is the infection of pregnant women, which may cause congenital rubella syndrome in developing babies.
Rubella IgG/IgM Rapid test is a solid phase immunochromatographic assay for the rapid, qualitative and differential detection of IgG and IgM antibodies to Rubella virus in human serum plasma or whole blood. This test provides only a preliminary test result. Therefore, more specific alternative diagnosis method such as Sabin-Feldman dye test for IgG antibodies, the IgM-IFA (Immuno-fluorescent Antibody) test and the PCR test must be used in order to obtain a confirmation of Rubella infection.
Rubella IgG/IgM test device has 3 pre-coated lines, "G" (Rubella IgG Test Line), "M" (Rubella IgM Test Line) and "C" (Control Line) on the surface of the membrane. All three lines in result window are not visible before applying any samples. The "Control Line" is used for procedural control. Control line should always appear if the test procedure is performed properly and the test reagents of control line are working. A purple "G" and "M" lines will be visible in the result window if there are enough IgG and/or IgM antibodies to Rubella virus in the sample. If IgG and/or IgM antibodies to Rubella virus are not present in the sample, there is no color appearance in "G" and/or "M".
