General screen for carrier status and assessment of CF risk.
This test will identify approximately 90% of Cystic Fibrosis (CF) mutations in the Caucasian population, and 97% in the Ashkenazi Jewish population.

4.0 mL Whole Blood in a Lavender Top Tube - EDTA
5.0 mL(3.0mL) Whole Blood in a Yellow Top Tube - ACD (Solution A or B)
or
5.0 mL (3.0mL) Whole Blood in a Green Top Tube - Na Heparin
or
5.0 mL (3.0mL) Whole Blood in a Navy Blue Top Tube - EDTA
or
5.0 mL (3.0mL) Whole Blood in a Green Top Tube - Li Heparin
or
2.0 mL Saliva collected in an Oragene Self-Collection Kit (would need to request from Quest)
Saliva: Rinse mouth, spit into collection tube until liquid phase reaches mark, seal with cap, replace funnel with small cap. See package insert. Store and ship room temperature. Do not freeze. The Oragene reagent is released from the cap. The reagent stabilizes/releases DNA from saliva.
For Genetic Testing, original tube required. Aliquots for other testing from original tube are permitted, if performed without cross contamination of samples and using sterile techniques. Rinse mouth prior to spitting.
Saliva
Room temperature: 14 days
Refrigerated: 14 days
Frozen: Call lab
8 days Ambient (preferred)
8 days Refrigerated
Specimen stability is crucial. Store and ship room temperature immediately. Do not freeze.
Order must indicate the ethnicity of the patient
3.0 mL Whole Blood
Refer to Interpretive Results
Limitations:
Approximately 18% of affected Caucasian individuals have only one detectable mutation and 1% have no detectable mutations when using this screen.
