Routine blood analysis and serum chemistries are of limited value, and findings generally are nonspecific.

Serologic testing for rheumatologic disease or vasculitis (eg, antinuclear antibodies, rheumatoid factor, erythrocyte sedimentation rate, C-reactive protein, anticitrulline antibody, antineutrophil cytoplasmic antibodies, antiglomerular basement membrane) may be appropriate in specific cases, as may serum precipitins for common hypersensitivity antigens. ACE testing is not very specific or sensitive but may offer a confirmatory clue to the diagnosis of sarcoidosis.
