From: Monitoring heparin therapy: stability of two different anti-Xa assays using blood samples collected in citrate-containing and CTAD tubes

Fig. 8

Stability of CTAD plasma samples from patients treated with LMWH. Anti-factor Xa activity scatter plots (A and C) and Bland–Altman plots (B and D) analysed with the Siemens and Stago analyser/reagent pairs, respectively. Results are plotted as the difference (y axis) in anti-factor Xa activity between the analysis after 6 h (T6P), 4 h (T4P)and 1 h (T1P) of storage at room temperature. *P < 0.05, **P < 0.01, ***P < 0.001, NS: Not significant (ANOVA or non-parametric Friedman test)
