Uremia and Thrombotic Microangiopathy: Conditions That May Havethe Same Manifestation

Figures & data

Table 1.  The platelet aggregation rate was tested at different time points during treatment.

Platelet aggregation rate (%)	Day 1	Day 10	Day 30	Day 50	Day 70
60 s	8.94	11.17	26.53	49.00	46.35
180 s	20.83	31.07	42.22	61.33	62.22
300 s	39.11	39.81	48.25	66.67	68.25

Notes: The initial rate of aggregation after adding adenosine-diphosphate (%/s) is shown in this table. With regular treatment, the platelet aggregation rate improved gradually. On day 50 of treatment (day 20 of regular dialysis), the platelet aggregation rate returned to normal (normal reference level = 44.7–77.8%).
