Not Enough Antigen Negative Units?
Let’s fix that. Empower your Immunohematology Reference Lab with fast, affordable, and scalable donor genotyping
The Challenge
Across the country, IRLs face the same critical problem – not enough antigen-negative units available locally to support patients with alloantibodies or complex transfusion needs. They find:
- Importing units is expensive and time-consuming.
- Manual antigen screening drains staff hours and delays patient care.
Your patients deserve better – and your donors can make it happen.
Let’s build your antigen-negative donor pool
Contact us today to discuss how we can help your IRL achieve self-sufficiency. Our genomics team will contact you to discuss your specific needs.
The Solution
Build Your Own Antigen-Negative Donor Pool
We make it simple for IRLs to grow their own inventory of antigen-negative red cell units through high-throughput FDA-licensed PreciseType HEA testing.
- Send donors samples directly to our Genomics Lab.
- We perform FDA-licensed PreciseType HEA genotyping covering 36 antigens in one test.
- Results are transmitted directly to your donor database – no manual data entry.
- Once a donor is tested twice on separate occasions, all future RBC donations can be labeled antigen-negative in accordance with AABB standards.
The Result
– No more scrambling for compatible units.
– Fewer imports
– Faster, more confident patient support.
– A self-sustaining, data-driven donor pool – built for your local area.
Your outcome is a reliable, sustainable, local source of antigen-negative blood for your patients – without the cost, burden, or bottlenecks of in-house testing.

Frequently Asked Questions
Our core service is high throughput donor red cell antigen genotyping using the FDA licensed Immucor BioArray HEA (Human Erythrocyte Antigen) BeadChip Assay.
• This assay supports donor labeling for antigen negative units according to AABB and FDA guidance.
• Once a donor is tested twice with concordant results, the blood center may label the donor’s future units without the need for additional testing.
The FDA licensed donor panel includes:
• Rh system: D, C, c, E, e
• Kell system
• Duffy system
• Kidd system
• MNSs system
• Diego system
• Scianna system
• Lutheran system
• V/VS
• Hemoglobin S (Sickle Cell Trait) (Note: Hemoglobin S is not reported on patient samples.)
In addition to our donor HEA testing program, we also provide:
• ABO genotyping
• Rh genotyping
• HPA (Human Platelet Antigen) panel testing
• RHD and RHCE variant analysis
• Allele specific molecular sequencing for complex variants
• Comprehensive patient genotyping with electronic reports delivered via BloodHub
We provide complimentary shipping boxes and all necessary materials.
- Shipments are sent via FedEx Overnight.
- We accept sample deliveries 24/7, including weekends and holidays.
Yes. We have high‑throughput workflows capable of processing large donor batches:
- 96‑sample capacity per HEA batch run and we are capable of running multiple batches simultaneously.
- Two QIAGEN QIAsymphony DNA extractors supporting parallel extractions
Under 3 days from receipt.
Under 2 days, often faster depending on testing complexity.
Yes. National Center of Blood Groups is accredited by AABB, NY State, California State, and CLIA.
Donor HEA genotyping results are transmitted via Secure FTP (SFTP) directly to the customer.
• Results can then integrate seamlessly into your LIS or donor management system.
• Email alerts are automatically sent when results are ready.
This delivery method mirrors other FDA licensed genotyping result workflows used by donor testing providers.
• Patient reports are delivered as written electronic reports.
• All reports are uploaded directly to BloodHub.
• We set up each customer in BloodHub so test orders and results flow securely and efficiently.
We strongly recommend beginning with your most reliable, repeat donors.
• Once a donor has been tested twice with concordant results, additional genotyping is not required.
• This allows you to rapidly build a verified antigen typed donor inventory and maximize ROI.
Yes. Our FDA licensed HEA assay supports direct donor labeling once concordance is established.
Yes. Our leadership team is readily available for consultation regarding donor or patient genotyping, interpretation of results, and workflow questions.
Our two laboratory directors—Aaron J. Gottschalk, PhD and Sunitha Vege, MS—are accessible for consults, troubleshooting, and guidance.

If any discrepancies arise between your historical data and our genotyping results, our team will work directly with you to:
• Review both result sets
• Identify the source of the discrepancy
• Resolve differences in interpretation
• Determine the correct antigen or genotype status
• Provide guidance for donor labeling or patient care impact
We take discrepancies seriously and partner with customers until full resolution is achieved.
