The Coombs' test in veterinary medicine: past, present, future

Area of Science:

• Veterinary medicine
• Immunology
• Hematology

Background:

• The Coombs' test (antiglobulin test) is a key diagnostic tool.
• It is used in veterinary medicine for immune-mediated hemolytic anemia.
• It is used in human medicine for red blood cell alloantibody screening.

Purpose of the Study:

• To summarize the applications of the Coombs' test.
• To highlight limitations in current diagnostic sensitivity.
• To underscore the need for advanced technologies.

Main Methods:

• Review of standard Coombs' test reagents (polyspecific and monospecific).
• Discussion of potential for false-positive and false-negative results.
• Examination of sensitivity limitations in human and veterinary applications.

Main Results:

• The Coombs' test is widely applied but has known limitations.
• Inadequate sensitivity is a significant issue in both human and veterinary diagnostics.
• Development of more sensitive technologies is ongoing.

Conclusions:

• The standard Coombs' test remains valuable but requires careful interpretation.
• Sensitivity issues necessitate the exploration of alternative diagnostic approaches.
• Further research into enhanced antiglobulin testing is crucial for improved patient outcomes.
