PL-11 platelet function analyzer (SINNOWA Medical Science & Technology Co., Nanjing, China) is a newpoint-of-care apparatus for platelet function analysis via an automated impedance technique.
Platelet aggregation was detected using PL-11 platelet function analyzer  (SINNOWA Medical Science & Technology Co., Nanjing, China).
PL-11 counted platelets several times until it detected the lowest level.
Our study used MA[R.sub.AA] and MA[R.sub.ADP] to evaluate platelet function by PL-11 platelet function analyzer, demonstrating that the single adequate inhibition of either MA[R.sub.ADP] or MA[R.sub.AA] was not associated with the decreased risk of recurrent ischemic stroke/TIA; however, adequate inhibition of both MA[R.sub.ADP] and MA[R.sub.AA] could predict the lower risk of ischemic stroke/TIA recurrence.
The shortcomings of this study are as follows: (1) There is a limitation of MARAA and MARADP by PL-11: the cutoff values of adequate platelet function inhibition by different inductive agents were not confirmed, requiring large cohort studies; (2) the study did not involve adjusting the antiplatelet therapy for ineffective inhibition of platelet function.
