Test Description

FISH - Rapid detection of aneuploidy involving chromosomes X or Y. 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 X, Y, 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 X, or Y
  • Parent of this pregnancy has an extra chromosome (e.g., Down syndrome, XXX syndrome, Klinefelter syndrome)

Test Methods and Limitations
