*Normal distribution; the values were mean Β± standard deviation (range: minimum-maximum); value represents the significance by paired Studentβs -test. **Nonnormal distribution; the values were median Β± standard deviation (5thβ95th percentiles); value represents the significance by Wilcoxon ranked-pairs test. The bold values are statistically significant (), and bold mean % differences represent clinically significant variations, when compared with desirable bias [15]. NA: not available [15]. Tube I: 4.5βmL Labor Import lot 20100505 (concentration of K3EDTA inside the tube is not made known by Shandong Weigao Group Medical Polymer, Weihai, China). Tube II: 1.2βmL S-Monovette lot 0092201 with 1.6βmg K3EDTA (Sarstedt, NΓΌmbrecht, Germany). |
