Sex Chromosome Screening: Advanced Genetic Insights in Melbourne

While most prenatal tests focus on the 22 pairs of autosomes, Sex Chromosome Screening specifically evaluates the 23rd pair—the X and Y chromosomes that determine a baby’s biological sex. At Western Imaging for Women, we integrate this sophisticated analysis into our genome-wide NIPT protocol, providing expectant parents with a deeper understanding of their baby’s health as early as the 10-week milestone.

Located in Maribyrnong, our specialist clinic serves women from Sunshine, Footscray, Essendon, and more who are seeking clinical clarity beyond a standard blood test.

What Does Sex Chromosome Screening Identify?

Typically, a female has two X chromosomes (XX) and a male has one X and one Y chromosome (XY). However, variations in the number of these chromosomes can occur, which is what Sex Chromosome Screening is designed to detect.

Common conditions identified through this screening include:

• Turner Syndrome (Monosomy X): Occurs when a female is missing one X chromosome.

• Klinefelter Syndrome (XXY): Occurs when a male is born with an extra copy of the X chromosome.

• Triple X Syndrome (XXX): A condition where a female has three X chromosomes.

• Jacob’s Syndrome (XYY): A condition where a male has an extra Y chromosome.

The Benefit of Specialist Oversight

At our clinic, Sex Chromosome Screening is never a standalone blood draw. We believe that genetic information is most valuable when supported by expert diagnostic imaging and specialist consultation.

• Scan-First Protocol: We perform a specialist viability ultrasound before every collection to confirm dating and health, protecting you from the costs of a laboratory test if the pregnancy is not progressing.

• Immediate Verbal Results: Our obstetrician and gynaecology-trained doctors provide real-time feedback during your appointment, ensuring you aren’t left waiting for basic answers.

• High-Accuracy Gender Reveal: While the primary goal is health screening, this process allows us to identify your baby’s sex with significantly higher accuracy than early-stage ultrasound.

• Rapid Turnaround: Most results are returned to your GP or obstetrician within 3 to 5 working days of the sample reaching the lab.
