Genetic testing technology has inherent limitations—no test can fully translate and interpret all genetic information.
Even when no variants are found, this doesn't completely rule out the possibility of carrying a variant with personal or reproductive implications. Rather, a "no variants found" or "negative" result indicates a lower likelihood of carrying a variant in the tested genes.
For instance, with extended carrier screening that shows no variants, while having a child with a genetic condition remains possible, the risk is substantially lower than the general population risk.
