Transfusion Laboratory Tools

Blood component compatibility matrix, Rh phenotype nomenclature translator, and FMH assessment.

Blood Component Compatibility Matrix

Select the patient ABO and RhD group to view BSH-compliant red cell, plasma, and platelet issuing choices.

Patient Blood Group

Red Cells:Ideal: O RhD Positive | Alt: O RhD Negative

Plasma (FFP & Cryo):Ideal: O | Alt: A, B, AB

Platelets:Ideal: O RhD Positive | Alt: O RhD Negative, A RhD Positive, A RhD Negative

Note: D-negative females of childbearing potential (<50 years) must receive D-negative platelets or prophylactic Anti-D immunoglobulin if D-positive units are unavoidable.

Rh Phenotype Nomenclature Translator

Bi-directional conversion between Fisher-Race haplotype descriptors and Wiener shorthand notation.

Translation Mode

Haplotype 1 (Fisher-Race)

Haplotype 2 (Fisher-Race)

Wiener Nomenclature: R1 r

Fetal-Maternal Haemorrhage (FMH) Assessment & Anti-D

Estimate Fetal Red Cell Volume (FRCV) via Kleihauer acid-elution and calculate appropriate prophylactic Anti-D immunoglobulin dose.

Clinical Event / Gestation

Fetal Cells Counted

Adult Cells Counted (Fields Equivalent)

Estimated Fetal Red Cell Volume:0.00 mL

Required Anti-D Dose:500 IU (1 × 500 IU vials)
