Figure 2. Plasma PF4 increased in the presence of heparin.

Figure 2

Plasma PF4 levels were measured using the Zymutest PF4 ELISA kit. (A) Plasma PF4 levels 20 minutes after the start of dialysis distal to the dialyzer increased significantly compared to the pretreatment level. Data are the mean ± SD. N=20. *p<0.05. (B) In the absence of heparin, plasma PF4 levels remained unchanged from pretreatment levels. The addition of heparin did not increase predialyzer plasma PF4 levels. Data are the mean ± SD. N=15.
