(Standard) §486.344(c)(3) Ensure that the potential donor’s blood is typed using two
separate blood samples.
Interpretive Guidelines §486.344(c)(3)
Verify through the sample of donor records that two distinct samples of blood (e.g.,
during current patient admission and/or OPO evaluation) were collected from the donor
at two different times and submitted as separate specimens for ABO blood typing. If one
test was already performed by the hospital, then the OPO need only perform one
additional test. “Split samples” (that is, submitting two specimens from a common
sample derived from a single blood sample collection) do not meet this requirement.
