Many of the illnesses associated with CF are due to respiratory infections and lung complications. Newborn Screening Differential Diagnoses. 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.

Caucasians from Northern Europe and Ashkenazi Jews have the highest incidence of CF with about 1 in 25 individuals being CF carriers. The method used may vary, with some states performing a blood test to determine the level of immunoreactive trypsinogen (IRT) and others screening for CF with gene mutation testing. This blood sample is then sent to a lab for a preliminary cystic fibrosis test. Mayo Clinic (2001, February 09). According to Cystic Fibrosis Foundation, it is estimated that 30,000 Americans are living with CF and approximately 1,000 new cases are diagnosed every year. The Invitae Cystic Fibrosis Test analyzes the CFTR gene, which is associated with the conditions cystic fibrosis (CF) and congenital absence of the vas deferens (CAVD).Pathogenic variants in the CFTR gene inhibit the function of chloride channels across cell membranes. V 117:1028-1031. Everyone inherits two copies of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. Since CFTR levels are usually highest in the epithelial cells lining the internal surfaces of the bronchi of the lungs, pancreas, sweat glands, salivary glands, intestine, and reproductive organs, these are the areas most affected by CF.
