Conventional chromosome analysis supplemented with fluorescent in situ hybridisation (FISH) technology has been the mainstay of diagnostic cytogenetic testing for many years.

WRGL was one of the first laboratories in Australasia to embrace and introduce microarray diagnostic testing for constitutional analysis. Microarray is now considered the diagnostic platform of choice for the investigation of intellectual disability and developmental delay in children.

This powerful technology allows us to interrogate the whole genome with unparalleled resolution allowing the detection of sub-microscopic abnormalities.
WRGL provides a fully comprehensive cytogenetic service, including analysis of prenatal, postnatal and oncology  samples.

The postnatal service also includes analysis of chromosome instability syndromes: including Bloom's, Fanconi and Ataxia Telangiectasia syndromes. 

The prenatal team offers rapid aneuploidy detection using QF-PCR to complement chromosome analysis from amniotic fluid and chorionic villus sampling (CVS) specimens. 

The oncology service performs chromosome / FISH analysis of bone marrow, leukaemic blood, lymph nodes, solid tumours and paraffin embedded sections.

The cytogenetic laboratory participates in a number of external quality assurance schemes managed by the Australasian Society of Diagnostic Genetics (ASDG).  International best practice guidelines for laboratory testing are adhered to.
