Cord blood bank private banks, partly because most treatable conditions can't use one's own cord blood. Cord blood contains hematopoietic stem cells (which can differentiate only into blood cells), and should not be confused with embryonic stem cells or pluripotent stem cells, which can differentiate into any cell in the body. Cord blood stem cells are blood cell progenitors which can form red blood cells, white blood cells, and platelets. This is why cord blood cells are currently used to treat blood and immune system related genetic diseases, cancers, and blood disorders. On the possibility that cord blood stem cells could be used
Ethics of technology how to treat diseases and provide families in need with the resources to cope. A version of pre-natal testing, called tandem mass spectrometry, is a procedure that "measures levels and patterns of numerous metabolites in a single drop of blood, which are then used to identify potential diseases. Using this same drop of blood, tandem mass spectrometry enables the detection of at least four times the number of disorders than was possible with previous technologies." This allows for a cost-effective and fast method of pre-natal testing. However, critics of tandem mass spectrometry and technologies like it are concerned about the
