Shi 2020 donor whole-blood liters to process for a CD3+ DLI target
Shi 2020 donor whole-blood liters to process for a CD3+ DLI target: (recipient_weight_kg × cd3_target_per_kg × num_infusions) / (0.6 × donor_alc_per_ul × collection_efficiency × 1e6). Estimates CD3 as 60% of donor ALC. Caller assigns collection_efficiency in (0,1]; the paper used first-quartile 0.57. Deterministic published arithmetic with citation. Not an apheresis order; magent does not run a device or the paper's CD34 HPC algorithm.
