Test Identifier Information

 
Registration CodeCTGN
Method

Tissue is cleaned, finely chopped and cultured in growth medium for approximately 5-15 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) for cases of suspected mosaicism, including tissue-specific aneuploidy such as trisomy 8, Pallister-Killian syndrome [i(12)(p)] 

PLEASE NOTE: karyotyping of Fetal Tissues and Products of Conception is no longer performed at this laboratory.  Where clinically relevant, testing is now performed firstly by QF-PCR (to screen for common aneuploidy and maternal cell contamination) followed by a MICROARRAY if QF-PCR result is normal.

Indications for QF-PCR+Microarray:                                                                         

Recurrent miscarriage (defined as ≥ 3)                                              

Abnormalities on U/S or abnormal fetal phenotype                           

Family history of a chromosomal rearrangement

 

Any referrals with no clinical indications or indications not meeting the above criteria, will have DNA extracted and stored only; no testing will be performed.  If testing is required, clinical information must be supplied.  

Please refer to tests QF-PCR and Microarray for referral indications and specific specimen requirements.
