Birth Tissue Collection

We work directly with hospitals who offer labor and delivery services to safely and ethically collect birth tissue like placentas, umbilical cords, and amniotic fluid. All tissues are collected after a healthy delivery, with informed consent from the mother—collection does not interfere with the health or comfort of mother or baby.

Cardinal Biologicals is actively seeking new partnerships with labor and delivery hospitals for the collection of umbilical cord blood. If you are interested in learning more about partnering with us, please reach out for more information.

Semen Donor Program

Our semen donor program collects seminal fluid samples from healthy males, which is invaluable in research towards early detection of prostate cancer. All samples are viral tested in an FDA-approved facility.

All semen samples are meant to be used for research purposes only, and are not used in fertility applications.
