The Collection Process
Cord blood collection happens after the umbilical cord has been cut and is extracted from the fetal end of the cord, diverting up to 75 +/- 23 mL from the neonate. It is usually done within 10 minutes of giving birth.
Additional stem cells may be collected from the placenta via Placenta Cord Banking. After the health care provider draws the cord blood from the placental end of the umbilical cord, the placenta is couriered to the stem cell laboratory, where it is processed for additional stem cells.
An adequate cord blood collection requires at least 75 mL in order to ensure that there will be enough cells to be used for a transplantation.
Before the cord blood is stored for later use, it undergoes viral testing, including tests for HIV and Hepatitis B and C, and tissue typing (to determine HLA type). It will also be examined for nucleated cell count, cell viability, blood group antigen (ABO & Rh), molecule cluster (CD34), and bacterial & fungal growth.

Famous quotes containing the words collection and/or process:
“It’s rather grisly, isnt it, how soon a living man becomes nothing more than a collection of stocks and bonds and debts and real estate?”
—John Dos Passos (1896–1970)
“Rules and particular inferences alike are justified by being brought into agreement with each other. A rule is amended if it yields an inference we are unwilling to accept; an inference is rejected if it violates a rule we are unwilling to amend. The process of justification is the delicate one of making mutual adjustments between rules and accepted inferences; and in the agreement achieved lies the only justification needed for either.”
—Nelson Goodman (b. 1906)
