HelpTest ID CKDGP Cystic Kidney Disease Gene Panel, Varies
Ordering Guidance
Targeted testing for familial variants (also called site-specific or known mutations/variants testing) is available for the genes on this panel. See FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.
Customization of this panel and single gene analysis for any gene present on this panel are available. For more information, see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.
Additional Testing Requirements
All prenatal specimens must be accompanied by a maternal blood specimen; order MATCC / Maternal Cell Contamination, Molecular Analysis, Varies on the maternal specimen as this must be a different order number than the prenatal specimen.
Shipping Instructions
Specimen preferred to arrive within 96 hours of collection.
Specimen Required
Patient Preparation: A previous bone marrow transplant from an allogenic donor will interfere with testing. For instructions for testing patients who have received a bone marrow transplant, call 800-533-1710.

Testing Algorithm
For prenatal specimens only:
If an amniotic fluid specimen or nonconfluent cultures are received, amniotic fluid culture for a genetic test will be performed at an additional charge.
If a chorionic villi specimen is received, fibroblast culture for a genetic test will be performed at an additional charge.
For any prenatal specimen received, maternal cell contamination testing will be performed at an additional charge.
