Here is a clear comparison between LDPRBC and PRBC:

PRBC vs. LDPRBC

Feature	PRBC (Packed Red Blood Cells)	LDPRBC (Leukodepleted PRBC)
Definition	Standard concentrated RBC unit prepared from whole blood by removing plasma	PRBC that has undergone leukoreduction to remove white blood cells
WBC content	Contains white blood cells (leukocytes)	<5 × 10⁶ WBCs per unit (must retain ≥85% of original red cells)
Method	Centrifugation of whole blood	Filtration (standard method); prestorage preferred over bedside
CMV risk	Present	Significantly reduced (comparable to using CMV-negative units)
Febrile non-hemolytic transfusion reactions (FNHTR)	Higher risk (caused by cytokines from stored WBCs)	Reduced risk - prestorage leukoreduction prevents cytokine accumulation
HLA alloimmunization	Higher risk	Reduced - indicated for potential transplant patients and platelet-refractory patients
Transfusion-related immunomodulation (TRIM)	Present	Mitigated
TA-GvHD prevention	No	No - leukoreduction does NOT prevent TA-GvHD (irradiation is required for that)
Cost	Lower	Higher
Shelf life	42 days (refrigerated)	Same as standard PRBC if prestorage filtered

Patients with a history of febrile non-hemolytic transfusion reactions
Immunocompromised patients (chemotherapy, HIV, etc.)
Transplant candidates and recipients (to prevent HLA alloimmunization)
Pregnant women
Prevention of CMV transmission in at-risk patients
Patients requiring multiple transfusions (to prevent platelet refractoriness)

Leukoreduction prevents:

Leukoreduction does NOT prevent:

Transfusion-associated graft-versus-host disease (TA-GvHD) - irradiation is needed for this
