What is this test?
This test determines the ABO blood group and Rh(D) status. The information is important for transfusion, pregnancy, and certain medical procedures.
Why might it be ordered?
- Before transfusion, surgery, or another procedure that requires blood-group compatibility.
- During pregnancy as part of blood-group compatibility assessment.
- When an official laboratory determination is required rather than a remembered result or old document.
What sample is needed?
A blood specimen is collected and identified under laboratory rules. A separate confirmatory specimen may be required for transfusion purposes.
How should you prepare?
Dietary preparation is usually unnecessary, but identity checks and correct specimen labelling are critical. Bring requested documents and follow staff instructions.
How should you understand the result?
The report states the ABO group and Rh(D) status. Rare or unclear reactions may require additional laboratory investigation.
