InSight: Prenatal Amnio Aneuploid (FISH) Testing for Chromosomes 13, 18, 21, and XY
- Direct Amnio FISH
- Direct Prenatal FISH
- InSight FISH
- Prenatal Aneuploid
- Prenatal FISH
- Prenatal FISH for 13, 18, 21, and XY
Rapid direct identification of common prenatal aneuploidy (specific for 13, 18, 21, and XY). If specimen volume is too small, then direct FISH may not be performed and results may be obtained if cultured chromosome studies are ordered.
Detects the most common aneuploidies, 13, 18, 21, and XY. Abnormal results should have banded chromosome confirmation.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).
Fluorescence in situ hybridization (FISH)
3 to 5 mL
3 mL (Note: This volume does not allow for repeat testing.)
Causes for Rejection
Frozen amniotic fluid; wrong specimen; low volume; specimen in fixative; blood specimen; hypocellular
Pertinent medical findings should accompany request for FISH. It is recommended that InSight FISH testing be performed concurrently with prenatal chromosome analysis. Abnormal results should have banded chromosome confirmation.
