The measurement of plasma homocysteine concentrations may be important both in health care and preventive medicine, provided that it is applied correctly, and that blood sampling, transport, and assays are state-of-the art procedures.
The haematopoietic stem cells remaining in the placenta after the umbilical cord has been cut can substitute for bone marrow in transplantations. It is argued that these cells should be retrieved and kept frozen as the child's personal biological spare part. A pilot, population-based collection of cord blood was carried out in a small provincial in Denmark. It was found that the pregnant women supported the concept (89%), that the midwives and technicians could carry out sampling and freezing after a short instruction period, and that the cost of sampling and storing for 75 years approx. DKK 12,000 per child. The project group is now seeking partners for further development of the concept.
