Summary
Cystic Fibrosis (CF) carrier screening models are being evaluated. The antenatal couple model shows the most promise for routine implementation in healthcare settings.
Area of Science:
- Medical Genetics
- Public Health Screening
Background:
- Cystic Fibrosis (CF) carrier screening is crucial for reproductive planning.
- Various screening models have undergone pilot testing.
Purpose of the Study:
- To evaluate different models of Cystic Fibrosis carrier screening.
- To determine the optimal mode of delivery for CF carrier screening programs.
Main Methods:
- Pilot trials of different CF carrier screening strategies.
- Analysis of data from screening programs in primary care and antenatal clinics.
Main Results:
- Opportunistic and cascade testing are not considered true screening methods.
- Sufficient data exists for antenatal clinic-based screening to determine optimal delivery.
- The antenatal couple model is the most data-supported approach.
Conclusions:
- The antenatal couple model is likely to be the standard for routine Cystic Fibrosis carrier screening.
- Future CF carrier screening services will likely adopt the antenatal couple approach.
