Each Stemell umbilical cord blood and umbilical cord tissue donor completes a series of questions to ensure that the donor does not have a medical history that places her at an increased risk for the transmission of infectious disease. Qualified staff and our quality assurance department will review the medical history of the donor.

The donor undergoes a physical examination by a healthcare professional that includes a blood draw for serology testing. Additionally, an umbilical cord tissue sample will be taken. The sample will be cultured following recovery and will be analyzed to detect the presence of any bacterial and fungal contaminants. All test results for serology, aerobic and anaerobic bacteria, fungi, slowly growing bacteria, infectious disease, and all the other Stemell donor parameters are reviewed prior to the release of any allografts. Only allografts from donors with acceptable test results and acceptable parameters in conformance with Stemell standards, as well as the standards of all state and federal regulatory bodies, will be released. Stemell umbilical cord blood and umbilical cord tissue donors will recover in U.S.-based hospitals.

Stemell has devoted numerous resources and energy to ensuring that all our donors are fully screened for any risk of infectious disease. Also, all of Stemell’s allograft products are specifically processed to ensure the dual goals of maximizing patient safety and retaining the native characteristics of the cord blood and cord tissues.

To ensure patient safety, screening and testing are performed for each donor. Donor screening includes a review of both the donor’s medical history and social history to ensure that the donor has not engaged in behaviors that place her at an increased risk for the transmission of infectious disease and to ensure that the donor has not shown signs or symptoms of illnesses.

Donor Screening

The donated human umbilical cord tissue/blood has been determined to be suitable for transplantation by a licensed physician: the Medical Director of the U.S-based tissue bank. The donor has been deemed free of risk factors for and clinical evidence of infection due to relevant communicable diseases and other exclusionary disease conditions through review of donor records, including medical/behavior risk assessment, medical records, and a recent physical examination.

Additionally, testing of a qualified blood sample indicates that the donor is nonreactive or negative for the following communicable disease markers:


  • Lyme disease
  • HIV I
  • HIV II
  • HTLV I
  • Hepatitis B
  • Hepatitis C
  • Syphilis
  • HBV
  • West Nile Virus
  • Chagas Disease (T-Cruzi)
  • CMV
