No. Cord blood and cord tissue should be kept at room temperature from the time of collection until the time the specimens are processed at our laboratory. Exposure to high or low temperatures can result in a significant loss of stem cell viability. The combination of MiracleCord's specially designed StemCare collection kit with built-in thermal stabilizers, and the utilization of our direct medical courier service ensures that your baby's cord blood and cord tissue will be kept at a consistent temperature from your hospital room to our laboratory.
