Hemolysis, packed cell volume (PCV), and total hemoglobin concentration (HGB) measured in stored canine packed red blood cells (pRBC) units for varying periods of time.
| Storage time group | n | Hemolysis (%) | PCV (%) | Total HGB (g/dL) | |||
|---|---|---|---|---|---|---|---|
| Mean | SD | Mean | SD | Mean | SD | ||
| t0 | 1854 | 0.07 | 0.11 | 63 | 3 | 21.77 | 6.86 |
| t1 | 47 | 0.31 | 0.70 | 61 | 4 | 21.45 | 1.60 |
| t2 | 30 | 0.53 | 0.50 | 60 | 5 | 20.57 | 1.66 |
| t3 | 70 | 0.76 | 0.70 | 60 | 5 | 20.73 | 2.02 |
| t4 | 2073 | 0.89 | 0.75 | 61 | 6 | 21.01 | 1.65 |
| t5 | 1,327 | 0.9 | 0.64 | 63 | 5 | 21.25 | 1.41 |
| t6 | 182 | 0.86 | 0.56 | 64 | 6 | 21.45 | 1.30 |
Hemolysis in canine units increased progressively with storage duration. Values are mean and standard deviation (SD). PCV: packed cell volume; HGB: hemoglobin; n: number of units; t0: tested within 72 h after processing; t1: tested after 4–7 days of storage; t2: tested after 8–14 days of storage; t3: tested after 15–21 days of storage; t4: tested after 22–28 days of storage; t5: tested after 29–35 days of storage; t6: tested after 36–42 days of storage.
