Test Identifier Information

 
Registration CodeCTGN
Method

Fetal cells (amniocytes) are cultured in growth medium for approximately 10 days and then harvested at the metaphase stage of the cell cycle when chromosomes are most condensed and visible by light microscopy . Microscopic analysis (karyotyping) is performed on GTL-banded chromosome preparations. 

Diagnostic Use / Indications

Detection of microscopically visible chromosome rearrangements (>10Mb). ie.

Suspected chromosome aneuploidy eg. Monosomy X (Turner syndrome), Trisomy including mosaicism

Confirmation of abnormal rapid FISH screen

Additional Information

Samples must be sterile. Very occasionally, poor cell growth will result in a delayed result. This is more frequent with heavily blood-stained samples.
