Sequential isolation
Counting protocolThe donor difference
Our LeukoLab Donor Care and Management facilities in the Boston and San Francisco Bay Areas have supplied researchers for over two decades. Donor depth is the reason collections land on schedule.
Screened, licensed, supervised
Industry oversight
Donors are re-screened every three months. Age, sex, HLA type and medical history are recorded; screening covers viral status, CBC and changes in health or medication. Clinicians, nurses and physicians oversee care; collection protocols and consent are IRB-approved and HIPAA-compliant.

Frequently asked questions
How big is your donor pool?
Thousands of qualified donors, filterable by gender, age, BMI, smoking status, blood type, HLA, race, ethnicity and GMP eligibility.
How diverse is the donor pool?
We work to diversify by ethnicity, age and other attributes. Age and BMI are verified; ethnicity, smoking status and medications are self-reported.
Is it possible to recall donors?
Yes. We use strategies that maximize recallability.
What affects donor availability?
Deferral periods after a last donation, willingness to take part in a collection type, and passing screening. Donors are re-screened quarterly, and we recommend alternatives when a donor is unavailable.
How do you define a healthy donor?
A multi-step process:
- A questionnaire screens for conditions such as high blood pressure, cancer, diabetes, hepatitis, HIV and autoimmune disorders.
- An in-person clinical screening reviews history and medications, runs a CBC, tests for Hepatitis B, Hepatitis C and HIV, and includes a physical assessment.
Can I request specific donor attributes?
Yes; requests may affect fulfillment time and cost.
- Gender; age 18–55 (collection-specific limits); BMI range
- ABO/Rh blood type (rare types add lead time)
- CMV status (closer or day-of testing on request)
- HLA typing up to 6-digit resolution by NGS
- Self-reported: race (Census categories), ethnicity, smoker status (past year), medication use (none for 2 days before collection)
Do you compensate donors?
Yes, donors are compensated for their time.
