What is the regulating agency for Blood Banking?

Food and Drug Administration


Blood Banking seeks accreditation from...

American Association of Blood Banks (AABB)


Definition: a facility involved in the collection, storage, processing, and distribution of human blood and blood products for transfusion

A blood bank laboratory


After collection, _____ ______ is allowed to cool to room temperature if ________ are to be prepared from the unit.

-Whole blood


After collection, ______ ______ is cooled between 1C-10C if the unit is to be processed for ______ ______

-Whole blood
-frozen plasma


What is the difference between FFP and FP24 regarding preparation?

FFP must be prepared within 8 hours of collection of the whole blood unit
FP24 may be prepared up to 24 hours following collection of the whole blood unit


What is the required temperature for storing blood products such as whole blood, RBCs, or thawed plasma, in a refrigerator?

1C to 6C


What is the required temperature for storing frozen plasma and cryo in freezers?

-18C or lower


What is the required temperature for storing frozen RBCs in freezers?

-65C or lower


What is the required temperature for platelet incubators?

20C - 24C


True or False:
Tests must be performed at each donation regardless of the number of times a donor has previously donated.



True or False:
Labeling of blood products occurs only after there have been no discrepancies in the ABO and Rh testing.

False, there should be no discrepancies in ABO and Rh testing as well as the absence of detectable antibodies in the plasma-containing components, nonreactive viral marker tests, and nonreactive syphilis test


When a blood bank receives a shipment what are they required to do to each RBC-containing product?

Reconfirm the labeled ABO


The Rh type of all Rh-_______ units must be reconfirmed when a shipment is received at a blood bank



A minimum of ___ identifiers is required for patient samples used for blood bank testing.

2 identifiers; The patient's full name and 1 other unique identifier


This type of routine testing allows better utilization of blood supplies; ABO and Rh testing and antibody screening are performed; the patient's transfusion record is checked; and if an antibody is detected the antibody is identified, and compatible units are reserved for the patient.

Type and Screen


This type of routine testing reserves completely tested and crossmatched blood for the patient

Type and Crossmatch


This type of routine testing includes determination of the ABO group and Rh type of the mother and antibody screen for antibodies that have the potential to cause HDFN

Prenatal Evaluation


This type of routine testing requires that all women admitted for delivery be tested to determine their Rh status. If mom is Rh-negative and baby is Rh-positive, the maternal sample is further evaluated to detect a fetomaternal hemorrhage (FMH)

Postpartum Evaluation


What 3 tests are used to test for FMH >30 mL whole blood?

Kleihauer-Betke Test, flow cytometry, or enzyme-linked antiglobulin test


What is required in order for blood components to be released to the designated recipient after pretransfusion testing is complete?

Written request with proper patient identification (2 unique identifiers)


What can an immune reaction to a drug, a disease state, or a delayed hemolytic transfusion reaction cause?

Positive DAT


What may mask the presence of clinically significant alloantibodies and requires the removal of RBC-bound autoantibody followed by serum autoadsorption?

Warm autoantibodies


What may cause ABO discrepancies, a positive DAT, and may mask clinically significant alloantibodies?

Cold autoantibodies


What requires the removal of RBC-bound autoantibody using 37C saline?

Cold autoantibodies


These are manuals outlining the operations of the laboratory.

Standard Operating Procedures (SOPs)


These devices produce sterile welds between two pieces of compatible tubing.

Sterile connecting devices


This process renders donor lymphocytes nonfunctional and protects against graft-versus-host disease.



RBCs stored in freezers maintained at -65C or lower are frozen in what?

40% glycerol


Some tissues require storage in an ultralow freezer at what temperature?

-80C or lower
