Do you recheck screening labs (ESR, BUN/Cr, urinalysis, ANA, etc) for patients with recurrent small vessel vasculitis of unknown origin with each flare?
Answer from: at Academic Institution
If the recurrences occur 6 or more months apart, I would recheck the studies to exclude SLE. If the episodes are chronic, I would recheck at least once a year for the same reason or whenever there are new suggestive symptoms of LE.
