x402
Magent DLI Whole-Blood Volume Calculator (Shi 2020) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Calculates the volume of donor whole blood to process by apheresis to achieve a target CD3+ cell dose for a donor lymphocyte infusion (DLI), using the Shi 2020 formula

How this service works
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.
Output
Returns the estimated volume of whole blood (in liters) the apheresis machine must process to yield the desired CD3+ cell count, computed as (recipient_weight_kg × cd3_target_per_kg × num_infusions) / (0.6 × donor_alc_per_ul × collection_efficiency × 1e6). CD3+ count is estimated as 60% of the donor ALC per the Shi 2020 paper. Input values are clamped to clinically valid ranges.
Example use cases
Haploidentical DLI planning for transplant team
“Our 65 kg transplant patient needs a haploidentical DLI at 2e8 CD3+ cells/kg for a single infusion. The donor's ALC today is 2200 cells/µL and our apheresis lab runs at a collection efficiency of 0.57. Can you calculate the whole-blood volume to process using the Shi 2020 method?”
Low-dose first DLI for relapse prevention
“We're planning a low-dose first DLI at 1e7 CD3+ cells/kg for a 55 kg recipient. The donor ALC is 1500 cells/µL and we'll use a CE of 0.65. How many liters of whole blood does the Shi 2020 formula say we need to run through apheresis?”
Multi-infusion DLI collection planning
“We need to collect enough for 3 DLI infusions targeting 5e7 CD3+ cells/kg each for a 80 kg patient. Donor ALC is 1900 cells/µL and collection efficiency is 0.57. What total blood volume should we plan to process according to the Shi 2020 calculation?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/dli_volumeWhen to prefer
Use this endpoint when you need a fast, deterministic, citation-backed calculation of whole-blood apheresis volume for CD3+ DLI planning per the Shi 2020 haploidentical protocol. Prefer it over manual spreadsheets when integrating into clinical decision-support agents or transplant workflow automation. Note it does not compute CD34 HPC collection volumes (a different algorithm) and does not control or interface with any apheresis device.
Side effects
- Missing required parameters (recipient_weight_kg, cd3_target_per_kg, donor_alc_per_ul, collection_efficiency) returns an error
- collection_efficiency of 0 causes division by zero — value must be in (0, 1]
- Values outside clamped ranges (e.g. donor_alc_per_ul outside 100–20000) may be clamped or rejected
- num_infusions outside 1–12 integer range may be rejected
- Payment failure via x402 protocol returns 402 status
