Important Note

  • 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 samples must have separate collection times.
  • Group O blood will be provided in an emergency or for pediatric patients if this test is indicated and not yet completed.

Specimen Type

Container

Options for off-site UCM locations (other than Hyde Park campus) for possible transfusion:

  • Provide your own TAN top tubes to draw an ABO2 verification
    • MUST be a completely separate draw from the Type and Screen sample (properly documented at least 1 minute apart)
  • Use a PINK or LAVENDER top in place of the tan top
    • Again, MUST be a completely separate draw from the Type and Screen sample (properly documented at least 1 minute apart)
  • If the ABO2 is completed when the Type and Screen is needed - would not need to have it done again

  • Blood Bank will provide inpatient nursing areas with a tan top tube for collection of ABO2ND for those patients requiring a second sample.  Tan top tubes are tracked and blood bank will only accept them for the patient for which they were issued.
  • Inpatient / outpatient phlebotomy and anesthesia pre-op clinic will have their own tan top tubes available for ABO2ND collection.
  • If there is a need for a transfusion, we must have 2 separate blood types on file.
    • Does not necessarily have to be done on the same day - but before a transfusion can take place, the requirement is to have 2 blood types on file.
