What your results can mean
Reading your report
A positive IgM usually suggests a recent or current infection and a positive IgG a past infection or immunity, but your doctor will read the result alongside your symptoms.
If the result is outside the usual range
A positive IgM or a rise in antibody between two samples can point to a recent adenovirus infection. A positive IgG is common and usually reflects past infection.
Who usually has this test
People with a lingering fever, sore throat, red eyes or chest infection when adenovirus is being considered.
Risks and aftercare
Bruising is usually small; you may be asked back for a second sample a few weeks later.

Questions about this test
Why is a swab often used for adenovirus instead of blood?
A swab from the nose, throat or eye can detect the virus directly during the illness. Blood antibody tests are more useful later or for research.
Can adenovirus cause pink eye?
Yes. Adenovirus is a common cause of conjunctivitis, which spreads easily. Hand washing helps prevent spread.
Why might two blood samples be needed?
A rise in antibody level between a sample taken early and one taken a few weeks later gives stronger evidence of a recent infection.
