Hemolysis, packed cell volume (PCV), and total hemoglobin concentration (HGB) measured in stored feline 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 | 2,287 | 0.05 | 0.06 | 51 | 3 | 16.94 | 1.25 |
| t1 | 52 | 0.11 | 0.16 | 52 | 3 | 16.68 | 1.02 |

| t3 | 49 | 0.48 | 0.21 | 48 | 5 | 16.66 | 1.13 |
| t4 | 577 | 0.66 | 0.50 | 48 | 5 | 16.60 | 1.35 |
| t5 | 183 | 0.89 | 0.57 | 48 | 5 | 16.70 | 1.35 |

Hemolysis in feline units increased progressively with storage duration. Values are mean and standard deviation (SD). PCV: packed cell volume; HGB: hemoglobin; 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.
