Patient's question:
When I was pregnant, the doctor asked me whether to keep the umbilical cord blood during delivery. This can be a lifesaver for the baby if he or she gets sick later. I agreed at the time, but I'd like to ask: what is the normal amount of umbilical cord blood flow? How much needs to be preserved to be stored?Doctor's answer:
The normal value of umbilical blood flow is related to the number of weeks of pregnancy. At 24 weeks, the average is 3.5, and the maximum cannot exceed 4.25. After 28 weeks, this value should be less than 3; if it exceeds, it is considered abnormal. Umbilical blood contains hematopoietic stem cells, which can be used to rebuild the blood and immune systems, treat leukemia, and other genetic diseases related to the blood and immune systems, and stores approximately 80 milliliters.
