What is this test?
This test investigates weak expression of the RhD antigen when routine typing is inconclusive. It supports decisions made under transfusion rules.
Why might it be ordered?
- For an unclear or weak Rh(D) typing reaction.
- When more precise classification is needed before transfusion or in pregnancy care.
What sample is needed?
A correctly identified blood specimen is required. A new confirmatory specimen may be requested in some situations.
How should you prepare?
Special dietary preparation is not expected. Report recent transfusion and follow all identity and documentation requirements.
How should you understand the result?
The report states whether weak RhD reactivity was found. Practical classification may depend on the purpose of testing and applicable transfusion rules.
