Test Code:
FVB004
Test Description
FISH - Rapid detection of aneuploidy involving chromosome 13. Assay offered in conjunction with chromosome study.
Indications for Testing
FISH - The FISH analysis does not detect structural chromosome abnormalities, mosaicism, and other numerical chromosome abnormalities (excluding 13, 18, and 21). The American College of Medical Genetics recommends that irreversible therapeutic action should not be initiated on the basis of FISH results alone.
Condition Description
FISH
- Screening result suggests aneuploidy
- Advanced maternal age
- One major or at least two minor fetal structural defects found on ultrasound
- Previous fetus or child with aneuploidy
- Parent of this pregnancy has a structural chromosome abnormality (e.g.,translocation, inversion) involving chromosome 13
Test Methods and Limitations
FISH - Fluorescence in situ hybridization (FISH) Fluorescence Microscopy
