A genetic carrier screening is a medical test that determines whether you or your partner is a "carrier" for certain genetic diseases and the odds that your child will inherit them. If you're a carrier, that means your DNA contains a genetic mutation that's associated with a disease, even though you may not have the condition yourself. If both you ...
Everyone has two sets of genes: one from Mom and one from Dad. When a sperm (carrying Dad’s DNA) fertilizes an egg (containing Mom’s DNA), those two sets of DNA (which include chromosomes and genes) combine to make a new mixture — the unique genome of their baby. A genetic disease is when a gene from one or both parents contains a mutation (a chang...
Ideally, parents will be tested for some genetic disorders before they conceive, but they can also be tested during pregnancy. In almost all cases, testing is recommended for one parent. Testing the second parent only becomes necessary if the first tests positive.Trusted SourceAmerican College of Obstetricians and GynecologistsCarrier Screening for...

Even if both you and your partner test positive as carriers of the same genetic mutation, there’s still only a 1 in 4 (or 25 percent) chance that your baby will have the disease. That’s because each of you has two sets of genes. Since you are carriers and don’t actually have the disease, that means you each have a second, healthy copy of the gene. ...
