Interpretation:
Interpretive report provided.
Specimen Requirements:
6.0 mL blood in a LAVENDER top tube.
See link for instructions for identification and labeling of Transfusion Service specimens. Sample Information (Opens in a new window)
Pediatric Specimen Requirements:
Less than 4 months old: 1 to 2 mL blood in a LAVENDER top tube.
4 months to 3 years: 3 mL blood in a LAVENDER top tube.
Reference Range:
Reflexed whenever antibody screen is positive.
Comments:
Serum red blood cell antibody specificity is determined by reacting patient serum with extended panel of reagent red blood cells of known phenotype. The clinical significance of some of the more commonly encountered red cell alloantibodies are summarized in the Transfusion Manual. Clinically significant alloantibodies (e.g., Rh, Kell, Duffy, Kidd) may be present in patients with hemolytic transfusion reactions or hemolytic disease of the newborn. Serum autoantibodies usually react with all panel cells (i.e. "panagglutinins"), and are present in the sera of 80% of patients with warm (IgG) autoimmune hemolytic anemia.

4 months to 3 years: 3 mL blood in a LAVENDER top tube.
Reference Range:
If the antibody screen is positive, antibody identification will automatically be performed.
Comments:
Should be ordered prior to a patient receiving a bone marrow transplant. When this specimen is drawn or as soon as the information is available, a BMT Transfusion Profile should also be ordered in EPIC. The BMT Transfusion Profile gives Nursing and the Transfusion Service details about the transplant, including the donor ABO/Rh type and what blood products (plasma products and red cell containing products) the patient should receive during and after they have received their transplant.

Pediatric Specimen Requirements:
Less than 4 months old: 1 to 2 mL blood in a LAVENDER top tube.
4 months to 3 years: 3 mL blood in a LAVENDER top tube.
Comments:
Following a suspected transfusion reaction, order a Transfusion Reaction workup, collect the post reaction sample, complete the form reporting the systems. If documenting the administration in EPIC, send the specimen and paperwork with the blood unit and all attached tubing and fluids to Transfusion Service.
NOTE: No additional blood products should be administered until the investigation is complete except for mild itching or hives controlled by antihistamine treatment.

Pediatric Specimen Requirements:
1.0 mL UMBILICAL CORD BLOOD in a LAVENDER top tube.
See link for instructions for identification and labeling of Transfusion Service specimens. Sample Information (Opens in a new window)
Reference Range:
Negative
Comments:
Demonstrates the presence of immunoglobulins, complement, or protein adsorbed to red cells of a neonate or infant. Of value in the diagnosis and evaluation of hemolytic anemia, hemolytic disease of the newborn, suspected transfusion reactions, and in some diseases.
Detects the presence of red blood cell-bound IgG and/or complement by agglutination using an antiglobulin (Coombs) reagent. Positive results occurring in cord blood are primarily due to maternal antibodies binding to the infant RBCs and can cause hemolytic disease of the newborn. Extended evaluation may include elution studies.
