Screen sample (documented collection time CANNOT be the same) -
NOTE: All blood bank samples must have HAND WRITTEN collection information on the label to be accepted (date MM/DD/YY or MM/DD/YYYY, time, and initials).
- If the ABO2ND has already been completed when the current Type and

when ordering a type and screen, an ABO2ND is not required

Additional Information
- This is a one-time test indicated only for patients with a
Type and Screen order who lack a previous blood type on file at
UCM. - This specimen must be collected in a separate draw from the
Type and Screen sample; both specimens must have separate
collections times. - Group O blood will be provided in an emergency or for
pediatricpatients if this test is indicated and not yet
completed. - If there is a need for a transfusion, at least two blood
types from at least two separate blood collection events must be
on file. - Does not necessarily have to be done on the same day
but before a type specific transfusion can take place, the
requirement is to have 2 blood types from different blood
collection events on file.
