PRECONCEPTION GENETIC COUNSELING
Carrier genetic screening before pregnancy or IVF
Carrier screening can identify selected recessive or X-linked conditions in people who often have no symptoms. A negative result reduces risk only for the genes and variants evaluated; it cannot remove all genetic risk.
Panel explained
Genes, variants and ancestry limitations are reviewed before testing.
Results confirmed
Positive or uncertain findings receive qualified interpretation.
Options remain personal
Testing informs choices without dictating a single family-building path.
BEFORE TESTING
Questions a carrier panel should answer
The value of testing depends on who is tested, the panel used, family history, timing and what decisions would follow a result.
Who is being tested
One or both genetic contributors may be screened, sequentially or together.
What the panel includes
Panels differ in genes, variants, methods and residual-risk estimates.
What happens after a result
Counseling may review partner testing, prenatal diagnosis, PGT-M, donor gametes or other options.
RESPONSIBLE USE
From consent to reproductive options
Review history
Family history, ancestry, prior testing and reproductive goals.
Choose and consent
Understand the panel, limitations and possible results.
Interpret findings
Confirm relevant variants and estimate residual risk.
Discuss options
Review reproductive choices without pressure or promises.
DECISION SUPPORT
Negative does not mean zero risk
A panel cannot evaluate every gene, variant or cause of disease. New information, family history or pregnancy findings may change recommendations.
- Obtain the full laboratory report, not only a summary.
- Ask how uncertain findings are handled.
- Do not make embryo or pregnancy decisions without clinical confirmation.
Important limitation: Carrier screening estimates selected inherited risks; it cannot predict every health outcome or guarantee an unaffected child.
Request a carrier-screening review
Send prior genetic reports and relevant family history so the team can explain the next appropriate counseling step.
