T-Cell Separation
Short Description : T-cell separation for chimerism studies
Also known as : [CD3+ cell enrichment]

DNA/RNA
Test performed by: LabPLUS - Dept. Diagnostic Genetics - Molecular Haematology

Specimen Collection

Note: All samples should be forwarded to LabPlus at room temperature within 24hours.


CPD12 mL CPD Blood (Preferred)
