Preferred Specimen
Pink 6.0mL
Other Acceptable Specimens
Lavender 6.0mL- Usable, but not preferred. Red top tubes are NOT the specimen of choice. Please contact the Blood Bank concerning samples collected in these tubes.
Instructions
Special Blood Bank Identification process is not required for isoagglutinin titers. However, specimens collected without the Blood Bank Identification process cannot be used for later crossmatch testing.
Reference Range
Clinical Significance
When performing an ABO incompatible stem cell transplant, high titers of isoagglutinins in the recipient will cause hemolysis of the transplant. Titers of isoagglutinins are therefore required prior to ABO incompatible transplants to determine the titer of naturally occurring anti-A and/or anti-B in the recipient.
