Unit Code 88880:
CFTR Gene, Known Mutation
Useful For
Suggests clinical disorders or settings where the test may be helpful
Diagnostic confirmation of cystic fibrosis when familial mutations
have been previously identified
Carrier screening of at-risk individuals when a mutation in the CFTR
gene has been identified in an affected family member
Genetics Test Information
Provides information that may help with selection of the correct test or proper submission of the test request
Documentation of the specific familial mutation(s) must be provided
with the specimen in order to perform this test.
Reflex Tests
Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Unit Code | Reporting Name | Available Separately | Always Performed |
| 80333 | Fibroblast Culture for Genetic Test | Yes | No |
| 80334 | Amniotic Fluid Culture/Genetic Test | Yes | No |
Testing Algorithm
Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Note: This testing algorithm only applies to prenatal
testing.
If amniotic fluid (non-confluent cultured cells) is received, amniotic
fluid culture/genetic test will be added and charged separately. If
chorionic villus specimen (non-confluent cultured cells) is received,
fibroblast culture for genetic test will be added and charged
separately.
