Table 3 Number of packed red blood cells (pRBC) units exceeding 1% of haemolysis at t0, t1 and t2

From: In vitro quality control analysis after processing and during storage of feline packed red blood cells units

  ≤ 1% (n = 739) > 1% (n = 48)
t0 (n = 489) 100% (n = 489) 0%
t1 (n = 180) 86.12% (n = 155) 13.88% (n = 25)
t2 (n = 118) 80.51% (n = 95) 19.49 (n = 23)
  1. χ2 (2) = 87.778; p < .001
  2. t0: units evaluated within 6 h after processing; t1: units re-tested after 29–35 days of storage; t2: units re-tested after 36–42 days of storage; ≤ 1%: units not exceeding 1% of haemolysis; > 1%: units exceeding 1% of haemolysis; n: number of units
