Test Code LAB2272 Type and Crossmatch for Red Blood Cells

Includes:

The patient's blood will be typed (ABO/Rh), screened for unexpected antibodies and the specified number of units will be crossmatched. These units will be held in Transfusion Service for 2 days. Unit reservation time can be extended to 3 days for specific patients upon request. The specimen is acceptable for 3 days.

Notes:

  • If, in an emergency, blood is needed prior to crossmatch, the attending physician MUST sign an Emergency Release form to obtain type specific blood or Group 0 units.  If all units initially requested are transfused, additional units may be added during the 3 day period.
  • Additional time will be required for patients with unexpected antibodies.
  • Draw blood specimens from site other than where transfusion needle(s) for administration of IV Fluids are located.
