In which situation may pretransfusion compatibility testing be eliminated?

Pretransfusion Compatibility 10

patient antibody to low-incidence antigen

What could be detected in a serological crossmatch that isn&#039;t detected in an antibody screen (IAT)?

strong in vitro antigen-antibody reactivity may be masked

Why is a hemolyzed specimen suboptimal for pretransfusion compatibility testing?

-transmissible disease testing
-antibody screen (IAT)
-Rh
-ABO
-Weak D if negative upon initial testing

Which of the following are required tests for donor blood?

-entering an incorrect crossmatch result
-misidentification of the patient
-entering incorrect ABO results into the laboratory information system (LIS)
-misidentification of an alloantibody because the lot number of cells didn&#039;t match the antigram
-misidentification of the recipient

Which of the following represent clerical errors in transfusion therapy?

detects most, but not all, ABO grouping mistakes

-two medical laboratory scientists have confirmed the patient&#039;s ABORh, and the results are concordant
-the patient&#039;s previous records show no difficulty with prior transfusion or unexpected antibodies
-no discrepancies between the ABO forward and reverse typing exist
-the current antibody screen is negative

An electronic crossmatch may be performed if:

unique patient medical number; A patient&#039;s name and unique identifying number are required. The system should include a mechanism to identify the collecting phlebotomist, but this does not necessarily have to be the initials. For example, an employee number could be used. Universal precautions apply when handling all patient specimens.

What information is essential on patient blood sample labels drawn for compatibility testing?

-Rh-positive RBCs should be avoided for females younger than and within child-bearing age
-Group O RBCs shall be selected
-Donor units must be conspicuously labeled that compatibility testing was not completed at the time of issue
-Rh-positive RBCs can be given to males and females older than child-bearing age

Which of the following apply to a trauma situation in which emergency blood is required before type and screen testing can be performed?

The &quot;minor crossmatch,&quot; which is no longer part of routine compatibility testing, included the crossmatch of:
