Summary

Plateletpheresis donation via apheresis causes a mean platelet count drop of 50,833/mm³ and a hematocrit reduction of 1.16%. Donor platelet count and yield correlate, suggesting personalized collection parameters for apheresis donors.

Hematology
Transfusion Medicine
Apheresis Technology

Background:

Increasing demand for platelet concentrates in clinical settings like oncology.
Single donor platelets (SDPs) collected via apheresis reduce transfusion-related complications.
Need to evaluate donor safety and eligibility for plateletpheresis.

Purpose of the Study:

To assess hematological changes in donors post-platelet donation using apheresis.
To provide insights into donor safety and optimize eligibility criteria.

Main Methods:

Pilot observational study of 30 plateletpheresis procedures.
Measurement of hematological parameters (platelet count, hematocrit) before and after donation.
Analysis of donor demographics and blood groups.

Keywords:

donor hematocrit platelet plateletpheresis single donor platelets

Main Results:

Mean post-donation platelet count decrease of 50,833/mm³.
Mean hematocrit reduction of 1.16% (range 0.5-2%).
Correlation observed between platelet yield and pre-donation platelet count, with higher yields showing greater hematocrit reduction.

Conclusions:

Automated cell separators enhance SDP quality and collection efficiency.
Personalized apheresis collection parameters are crucial, informed by the relationship between platelet yield and donor's pre-donation platelet count.
