Results are reported as meant ± SD. n = number of replicates (treated plasma units) done for each parameter. (A higher number of replicates was performed for a basic testing panel, with additional parameters included in a subset of studies.) IU/dL = International Units/deciliter.
The reference range was calculated from the mean ± 2 SD of untreated, conventional plasma.
For PT and PTT, the effect of PCT was calculated by subtracting the pre‐PCT values from the post‐PCT values.
