ACE Levels in Sarcoid Patients

The ACE level, the sensitivity is about only 75%, and there's specificity is also not good. The other thing you could consider particularly if the history is suggestive is immunoglobulin levels to rule out immunodeficiencies which might be a mimicur of sarcoid when I say this. But in general, I think we need to move quickly to make the diagnosis with what we need in this situation would be a biopsy.
