SINGLE-GENE CARRIER SCREENING
Dedicated genetic testing for cystic fibrosis
In addition to a comprehensive screening for more than 500 genetic disorders (Inheritest), we also offer screening for specific disorders, such as cystic fibrosis.
Cystic fibrosis is the most common life-threatening, autosomal recessive condition in the non-Hispanic white population. It affects about 1 in 2,500 individuals in the non-Hispanic white population and considerably less in other ethnic groups.1 CF leads to life threatening lung infections, digestive problems, diarrhea, poor growth and infertility.
Screening for Cystic Fibrosis
ACOG’s most recent recommendations state that carrier screening for CF “should be offered to all women who are considering pregnancy or are currently pregnant.”1

CF Carrier frequencies2
| Ethnicity | CF carrier risk in people with no family history of CF |
|---|---|
| Caucasian | 1 in 25 |
| African American | 1 in 61 |
| Hispanic | 1 in 58 |
| Ashkenazi Jewish | 1 in 24 |
| Asian | 1 in 94 |
Enhanced insight for CF risk
As CF is a common hereditary disorder in the US, we offer an additional safeguard. If a patient screens positive for CF, we offer her partner full gene-specific sequencing, reporting all disease-causing variants and variants of uncertain significance.
Determine if the baby is affected
For pregnancies at risk, we also offer prenatal testing to determine whether the baby has the parental mutations, saving patients time and additional testing.
Sample requirement and turnaround time
The screening test requires a blood, saliva or buccal swab sample and results are typically ready within 8 to 21 days. If a couple has not yet conceived, one partner is usually tested first. If a woman is already pregnant, a couple may opt to be tested at the same time.
