Patient History For Cystic Fibrosis (CF) Testing
  


Mnemonic: CFCIS-TRAN

Methodology: Polymerase Chain Reaction/Oligonucleotide Ligation
Performed: Mon, Wed, Fri
Reported: 8-12 days
Specimen Required: Collect: Lavender (EDTA), pink (K2EDTA), or yellow (ACD Solution A or B).

Specimen Preparation: Transport 3 mL whole blood. (Min: 1 mL)

Storage/Transport Temperature: Refrigerated.

Stability (collection to initiation of testing): Ambient: 72 hours; Refrigerated: 5 days; Frozen: Unacceptable
Reference Interval:
By report
Interpretive Data: The sample is tested to determine cis-trans status of R117H/5T and the IVS-8 poly 5T in the CF gene by allele-specific long range polymerase chain reaction (PCR) and oliogonucleotide ligation (OLA). Sensitivity and specificity for detection of these mutations are 99%.



Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.

Refer to Statement C under Testing Information at http://www.aruplab.com.
Note: It is important to note on the test form whether the test is to rule out affected or carrier status. Risk assessment is dependent on this information.
CPT Code(s): 83891 Isolation; 83900 Amplification; 83901 Multiplex amplification; 83914 x4 Mutation identification; 83909 Separation and identification; 83912 Interpretation and report - Additional CPT code modifiers may be required for procedures performed to test for oncologic or inherited disorders.
