Interpretation of Results

Negative / Undetectable Titre:
- No anti-D antibodies present.
- In pregnancy, this suggests no alloimmunization, and RhIg prophylaxis may be needed.
Low Titre (≤1:4 to 1:8):
- Minimal antibody levels, usually not concerning but requires monitoring.
Moderate Titre (1:16 to 1:32):
- Indicates possible sensitization. Further monitoring is needed to assess fetal risk.
High Titre (≥1:64):
- Suggests significant alloimmunization with increased risk of hemolytic disease of the fetus and newborn (HDFN).
- Requires close monitoring with Doppler ultrasound for fetal anemia and possible interventions (e.g., intrauterine transfusion).
