Choosing Clinical Laboratory Tests Wisely Guidelines:
Think carefully before repeating rheumatology and immunology tests. Do not repeat immunology tests in known positive patients (for example ANF, RF, ANF) on every admission.
If the test is strongly positive there is little benefit in repeating it ever. If a weak positive it could be repeated at 6 months. If negative we might repeat again at 6 months if we felt RA was likely.
Once decided if positive or negative for a patient there is no reason to repeat the test unless there is some major clinical change.
