Interference data for automated Optilite^® C1‐INH assay

	Chyle	Bilirubin	Hemoglobin	Triglyceride
Low	1.6%	8.9%	4.3%	−3.5%
MDP	3.1%	0.9%	6.2%	−1.7%
Normal range	1.3%	1.0%	3.5%	−1.5%

Serum samples with three different C1‐INH concentrations (one low concentration, one around the medical decision point (MDP) and one within the normal range) were spiked with one of four interferents or saline as a control. All samples were then run in the Optilite C1‐INH assay. The results represent percentage change observed in the presence of the interfering substance.
