Figure 1 Platelet aggregation test with light transmittance. The aggregation of platelets is judged as the change in light transmittance in platelet-rich plasma (PRP) by stimulation with different concentrations (from 4.0 μmol/L to 20 μmol/L) of adenosine diphosphate (ADP) recorded for 5 minutes. The degree of aggregation increases with the concentration of ADP (left). The y-axis is defined as 0% of transmittance value of PRP and 100% of platelet-poor plasma (PPP). Typical examples of a normal figure (middle) and of hyperaggregation (right) are given.
