|The American Red Cross reference laboratories provide assistance with routine and complex serological cases, selection of suitable donor units and technical and medical consultation.|
With more than 50 years of experience, world class expertise and locations to meet healthcare needs, our laboratories also offer educational programs and local lectures. Our laboratories follow rigorous quality standards and process controls to meet state and local regulatory requirements.

Molecular Blood Group and Platelet Testing
- Analysis of patient and donor samples for blood group and platelet antigens by DNA methods.
- DNA and RNA sequencing to resolve complex Rh blood group alleles, identify weak ABO subgroups, and characterize new mutations and null alleles or platelet antigen systems.
- Molecular testing can be used for:
- Typing a patient who has had multiple transfusions and/or has a positive Direct Antiglobulin Test
- Screening for antigen-negative donor units when antisera are in short supply or not available
- Resolving/confirming weak D or partial D
- Identifying e-variants
- Typing panels and rare donor cells
- HPA genotyping for NAIT and PTP
To submit a sample click here for the Molecular Testing Request Form:
- Detection and identification of HLA antibodies in sensitized patients and donors
- Determination of HLA types of patients and blood donors to assist in the provision of HLA-matched platelet transfusions
- HLA testing support for HSCT and organ transplantation, including monitoring of engraftment post-HSCT transplantation
- Identification of disease predisposition HLA gene for Celiac disease, narcolepsy, Ankyllosing spondylitis, and other
- Identification of drug hypersensitivity related HLA genes, including: HLA-B*5701 with Abacavir, HLA-B*1502 with Carbamazepine, and HLA-B*5801 with Allopurinol
