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:
“We’ll never know the worth of water till the well go dry.”
—18th-century Scottish proverb, collected in James Kelly, Complete Collection of Scottish Proverbs, no. 351 (1721)
“The American, if he has a spark of national feeling, will be humiliated by the very prospect of a foreigner’s visit to Congress—these, for the most part, illiterate hacks whose fancy vests are spotted with gravy, and whose speeches, hypocritical, unctuous, and slovenly, are spotted also with the gravy of political patronage, these persons are a reflection on the democratic process rather than of it; they expose it in its process rather than of it; they expose it in its underwear.”
—Mary McCarthy (1912–1989)
