ACOG Committee Opinion No. 348, November 2006

A statement published in November 2006 by the Committee on Obstetric Practice,
of the American College of Obstetricians and Gynecologists, provides the following
technique for obtaining a sample of umbilical cord blood:

    "Immediately after the delivery of the neonate, a segment
    of umbilical cord should be double-clamped,
    divided, and placed on the delivery table pending
    assignment of the 5-minute Apgar score." [1, p1321]

The same instruction is given by Turrentine (2003), a book used by physicians
preparing for board certification exams [2].  Both the ACOG committee and
Turrentine state that the cord sample can be discarded if the 5-minute Apgar score
is satisfactory, and the infant appears stable and vigorous.
