LabCorp and its Specialty Testing Group, a fully integrated portfolio of specialty and esoteric testing laboratories.
LabCorp is a leading provider of histocompatibility (human leukocyte antigen, or HLA) testing for bone marrow, other transplant-related services, and disease association testing.
LabCorp performs testing for either HLA class I or class II using highly robust molecular methods. LabCorp’s HLA testing is accredited by several agencies, including the American Society for Histocompatibility and Immunogenetics (ASHI) and the College of American Pathologists (CAP).
LabCorp is a contract lab for the National Marrow Donor Program. For more information about the National Marrow Donor Program and becoming a bone marrow donor, go to BeTheMatch.org.
Human leukocyte antigen (HLA) testing is performed when trying to find a suitable organ, tissue (bone marrow), or cord blood donor for transplantation.
The results of either HLA class I or class II typing can be used for bone marrow transplant donor screening. This screening is coordinated with various agencies that conduct drives to assist people in need of a bone marrow transplant. LabCorp also performs post-transplant engraftment monitoring, which involves testing samples for donor and recipient markers.
You may request a collection kit or contact bone marrow customer service at 800-533-1037, Monday through Friday, 8:00 am to 5:00 pm Eastern time.
Additional LabCorp Specialty Testing
ViroMed Laboratories, a LabCorp specialty lab, has a national reputation for expertise in providing comprehensive laboratory services to meet the unique testing needs of the bone marrow industry.
ViroMed’s CAP-accredited, CLIA-certified laboratory is FDA-registered for screening human cells, tissues, and cellular- and tissue-based products (HCT/Ps). ViroMed performs donor testing 7 days a week on multiple shifts, and provides customer support 24 hours a day, 7 days a week.
ViroMed incorporates quality assurance measures to monitor laboratory quality and customer satisfaction.
LabCorp's transplant testing service offers:
LabCorp offers multiple DNA-based methodologies for HLA typing:
LabCorp utilizes a combination of powerful technologies to analyze DNA sequences at HLA class I and class II loci:
LabCorp's software requires double-blind data entry by two independent technologists with a final review by a third technologist. When any new, undescribed antigens are present, the program can help determine which known antigens are most similar to the type seen in the sample.
Loci are available at various levels of resolution, including:
High-resolution typing implements additional PCR reactions along with a larger panel of DNA probes to define the antigens present at the allele level. These methods are similar to those employed for class I HLA typing in which PCR is used to amplify the DNA of interest (DRB, DQB, DQA, or DPB gene sequences), and probes determine which sequences are present in the amplified DNA. SSP, SBT, and Luminex methodologies are available.
*Polymerase chain reaction (PCR) is performed pursuant to an agreement with Roche Molecular Systems, Inc.
Benefits of LabCorp's transplant engraftment monitoring services include:
This test monitors the success of a bone marrow/stem cell transplant. The relative percentage of recipient and donor cells in post-transplant specimens is assessed.
Bone marrow engraftment monitoring is based on detection and comparison of STR DNA regions in the recipient and donor after transplantation.
Currently, LabCorp has 14 STR systems available for detecting genetic differences between recipient and donor. This test battery is useful in virtually all donor/recipient pairs except identical twins. The methodology is based on the PCR. The LabCorp procedures generally provide 3- to 7-day turnaround time and a higher sensitivity than other DNA tests historically used for engraftment monitoring.
Our PhD-level scientists are available to answer technical questions. For additional information, please call bone marrow customer service at 800-533-1037.
Healthcare providers often order HLA testing to aid in the diagnosis of a disease.
A disease association arises when an HLA type is more commonly seen in patients with a specific disease than in healthy patients. For example, the HLA allele B27 has a disease association with ankylosing spondylitis and certain forms of arthritis. Other disease associations commonly tested at LabCorp are the HLA disease associations for narcolepsy and celiac disease.
Since HLA is a key component of the immune system, it is becoming recognized that HLA types can affect drug sensitivity, vaccine effectiveness, and resistance to certain viruses. HLA typing is becoming an important aspect of personalized medicine.
LabCorp offers a number of specialized profiles to help with disease association:
