Detection of SP-D in serum and plasma collected using various anticoagulants.

Abstract

<p>a) SP-D concentrations were measured in samples collected into four different vacutainers during a single blood draw. b) Measured values of samples were normalized to the SP-D concentration in serum for each patient in order to compare the effect of the anticoagulant on the measured SP-D concentration. An asterisk (*) denotes values are significantly different by Wilcoxon signed rank test (for EDTA, p = 0.0156, and for Citrate, p = 0.0078).</p
