Intradermal injection of a heated (pasteurized) saline suspension of sarcoid tissue obtained from a sarcoid spleen or lymph node. In patients with active sarcoidosis a dusky red nodule develops slowly over the next few weeks at the injection site. Histologic examination, an essential part of the complete test, reveals sarcoid tissue.
