State of immunosuppression; coagulopathy; pre-existing liver or kidney disease; documented HIV positive; documented hepatitis B and/or C positive.\n* Medications and other drugs. Use of anti-platelet drugs within 7 days prior to blood draw or biopsy; use of anticoagulants within 60 days prior to blood draw or biopsy; active drug or alcohol use or dependence that, in the opinion of the biopsy surgeon, would interfere with post-procedure wound care.\n* Other.
