Help determine affected or carrier status for the 32 most common CF mutations
This assay detects as many as 90% of cystic fibrosis carriers in the Caucasian population. Within other ethnic groups, there may be higher or lower detection efficiency. Includes the mutation profile currently recommended by the ACMG and the ACOG.
Polymerase chain reaction (PCR); primer extension; flow-sorted bead array analysis
Cystic fibrosis (OMIM 602421) is a common genetic disorder resulting in chronic pulmonary and gastrointestinal/pancreatic disease. There is wide variability in clinical symptoms. CF is inherited in a recessive manner, which means that both parents must be carriers to have an affected child. When both parents are carriers, there is a 25% chance with each pregnancy that the child will be affected. Genetic counseling and CF molecular testing are recommended for the reproductive partners and at-risk family members of CF carriers.
LabCorp also offers Cystic Fibrosis (CF) Profile, 97 Mutations, CFplus®  for 97 CF-causing mutations, which has specific utility for partners of known carriers, equivocal/diagnostic cases, high-risk couples (previous affected child) for whom at least one mutation remains unidentified after ACMG/ACOG profile testing, or for those persons whose ethnicity requires testing for less common mutations.
Whole blood or LabCorp buccal swab kit (buccal swab collection kit contains instructions for use of a buccal swab)
7 mL whole blood or LabCorp buccal swab kit
3 mL whole blood or two buccal swabs
Lavender-top (EDTA) tube, yellow-top (ACD) tube, or LabCorp buccal swab kit
Maintain specimen at room temperature.
Causes for Rejection
Frozen specimen; hemolysis; quantity not sufficient for analysis; improper container; one buccal swab; wet buccal swab
Whole blood tube should be sent to the lab unopened. It is preferable not to perform additional testing on original tubes prior to PCR testing. A completed screening questionnaire must accompany specimens. Call 800-345-4363 to request forms, or photocopy the Cystic Fibrosis Screening Questionnaire from the Genetics Appendix online.
