The parvovirus test is performed to examine the presence of parvovirus 19. This virus is one of the primary causes of a common disease in children known as fifth disease (erythema infectiosum). Fifth disease typically only causes mild symptoms in children, but it can be dangerous for people with low immunity and especially pregnant women.
You may also hear different names for this test, such as parvovirus B19 IgG antibody, parvovirus B19 antibody, parvovirus B19 IgM, and Parvo B19.
Why Should I Get Tested for Parvovirus B19?
You will need this test if you observe any kind of rash or redness on your body. They could be the signs and symptoms of the fifth disease, though some people with parvovirus B19 may not show any symptoms.
The parvovirus B19 IgG antibody test can help your doctor identify past or current parvovirus infections in both cases.
How Is the Parvovirus B19 IgG Antibody Test Done?
A simple blood test will help your doctor find antibodies for parvovirus B19, a sign you have or have had the disease.
If you have sickle-cell disease, HIV, or spherocytosis (a genetic blood disorder), your doctor may also perform a complete blood count.
The parvovirus test results may vary according to your age, family history, and gender. People with Epstein-Barr antibodies or rheumatoid factors may get a false report.
Your doctor will explain the test results. Keep in mind that your test results will only show whether you have enough antibodies to fight the parvovirus. If you get positive results, that means you have parvovirus and the antibodies to fight it. If results turn out negative, you have not been exposed to the virus.
