Interferences
Human Anti-Murine Antibodies (HAMA) may develop leading to test interference in patients receiving murine-based agents for chemotherapy or tumor-imaging studies.
For testing performed at Weston: High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay.
