How accurate is genetic testing for cystic fibrosis?

A positive genetic carrier test for CF means that a person has an altered copy of the CF gene; this result is more than 99% accurate.

What is the primary genetic test for CF?

The CF gene mutation panel detects the common mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene on chromosome 7 to screen for or diagnose CF or to identify carriers of the disease.

How much does CF genetic testing cost?

Will my medical coverage (insurance/coupons) pay? The CF carrier test costs about $200 – $300 per person. You need to check with your own insurance company to see if they will pay.

What is a confirmatory test for cystic fibrosis?

There are two tests commonly used to diagnose cystic fibrosis (CF): a sweat test, which measures the amount of chloride in sweat, and a genetic test, which detects chromosomal mutations associated with the disease. Because of the severity of CF and the need for proactive treatment, newborns are routinely screened.

How common is the CF gene?

Cystic fibrosis is a common genetic disease within the white population in the United States. The disease occurs in 1 in 2,500 to 3,500 white newborns. Cystic fibrosis is less common in other ethnic groups, affecting about 1 in 17,000 African Americans and 1 in 31,000 Asian Americans.

Can cystic fibrosis be detected in utero?

Is it possible to find out if a fetus has cystic fibrosis? Testing can be done to learn if a fetus has CF or is a carrier. This is called prenatal diagnostic testing. This testing can be done as early as 10 weeks of pregnancy.

Can CF be detected before birth?

Your doctor may perform a prenatal screening to test for CF if both parents know they carry the gene. This is performed while you are pregnant. It checks for any health problems with your baby before he or she is born. The screening also can detect other genetic disorders.

Does insurance cover genetic testing pregnancy?

While the cost of genetic testing for pregnancy can range from less than $100 to over $1,000, most tests are covered by insurance. Insurance is more likely to cover testing if a pregnancy is considered high risk for a genetic or chromosome condition, but many options are covered in low risk pregnancies as well.

How much is a gender blood test without insurance?

The standard package, with results in 5 to 7 days, costs $79. For results in 72 hours, you’ll have to pay $149. Accuracy is said to be 99.9 percent at 8 weeks pregnant.

Which type of testing is most commonly used to diagnose cystic fibrosis?

A sweat test measures the amount of chloride, a part of salt, in Sweat. It is used to diagnose cystic fibrosis (CF). People with CF have a high level of chloride in their sweat. CF is a disease that causes mucus build-up in the lungs and other organs.

How is a sweat test done for CF?

The sweat test measures the amount of chloride in sweat. Kids with cystic fibrosis can have two to five times the normal amount of chloride in their sweat. In a sweat test, the skin is stimulated to produce enough sweat to be absorbed into a special collector and then analyzed.
