ELISA Development for Serum Hemeoxygenase-1 and Its Application to Patients with Acute Respiratory Distress Syndrome

Table 2

Evaluation of influence of serum interferences using the spike and recovery test.

	Serum HO-1 (ng/mL)	% coefficient variations (%)^b
Low, 1 ng/mL^a	98	10
Middle, 5 ng/mL^a	105	8
High, 10 ng/mL^a	104	9

^aLow, middle, and high mean known concentrations of purified HO-1; ^bthe acceptable range of coefficient variation is less than 10%. HO-1, hemeoxygenase-1.
