Parvovirus B19 Blood Test
Test Code: 163303
Specimen Type: Blood
Parvovirus B19 Blood Test (LabCorp)
This test measures both IgM and IgG antibodies to Parvovirus B19. Parvovirus is most commonly spread through respiratory fluids when an infected person sneezes or coughs. It can also be spread by blood or from an infected mother to her infant during pregnancy. It is important to note that while other types of parvovirus affect animals including dogs, B19 infects only humans. It cannot be spread from animals to people or vice versa. Parvovirus B19 typically affects children but people of any age can be infected. People infected with parvovirus B19 commonly develop the illness Fifth Disease. Symptoms of fifth disease are usually mild. The most common symptom is a red rash on the face. Other symptoms can include an itchy rash that spreads to other parts of the body, fatigue, fever, headaches, runny nose, and painful swollen joints.
Most parvovirus infections are mild and resolve on their own. In rare cases, it may cause more serious complications such as chronic anemia. People whose immune systems are weakened from other conditions such as cancer, HIV, or recent surgery may have a higher risk of complications from parvovirus and fifth disease. Since parvovirus symptoms are common to other illnesses, antibody testing can help identify and differentiate infections. IgM antibodies usually develop within 1-2 weeks of exposure and fade to undetectable levels over time. Positive IgM levels indicate a recent infection. IgG antibodies begin to develop several weeks after infection and will typically remain detectable for life even after the infection has resolved.
Parvovirus B19 antibody testing may be ordered when a person has common symptoms of fifth disease. Pregnant women who develop symptoms are commonly tested due to the potential risk the virus may pose to their infant.
Turnaround for this test is typically 2-5 business days.
