GENERAL INFORMATION
Testing Schedule Wednesday 
Expected TAT Within 14 days  
Clinical Use This is a qualitative genotyping test that provides information intended to be used for carrier testing in adults of reproductive age, as an aid in newborn screening, and in confirmatory diagnostic testing in newborns and children. This test is not indicated for use in fetal diagnostic or pre-implantation testing. This test is not intended for stand-alone diagnostic purposes. Personalized reports include risk assessment, concise genotype results, and clinical relevance. Further assessment is recommended when appropriate. Genetic Counseling is available through Access Genetics.

Method: Genomic DNA is evaluated using the Luminex xTAG Cystic Fibrosis 60 kit, an FDA-approved device employing a multiplex polymerase chain reaction (PCR) using oligonucleotide primers specific for regions of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. The resultant data is analyzed for 60 mutations and variants including the 23 mutations recommended by the American College of Medical Genetics and American College of Obstetricians and Gynecologists (ACMG/ACOG) for CF carrier testing. Reflex analysis is performed as recommended for intron 8-5T/7T/9T, I506V, I507V, and F508C variants. Results are interpreted by Board Certified Molecular Geneticists.
