Test Identifier Information

 
Registration CodeCTGN
Method

Solid 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.

Note this test is no longer routinely performed for investigations into FETAL LOSS. Please see below and refer to QF-PCR and Microarray tests for further details. Alternatively contact the lab 03 364 0881.

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 to investigate fetal loss is no longer routinely 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

Specimen Collection

 
Pre-Testing Requirements

Solid Tissue should be collected aseptically in RPMI Tissue Transport Medium in a universal container.

To order transport medium phone the CHL patient and client services 03 364 0484 between 09.00-17.00, Mon-Fri and allow at least one working day for delivery. 

In an emergency, the specimen can be collected into sterile saline.  

Specimen Collection Protocols

Tissue smaller than 1cm x 1cm should be collected aseptically into sterile transport medium (see above).

Larger specimens can be sent dry in a sterile pottle, without delay.

Patient SpecimenSolid tissue
