A doctor has provided 1 answer

A viral infection, like a heavy head cold, is one of the things that can affect an ANA test. Repeat it some time in the future unless a rheumatologist,who knows your case well, thinks you have an autoimmune disorder. The clinical picture makes the diagnosis.more likely than an ANA on its own.
