Y Chromosome Microdeletion Analysis

Methodology

This PCR-based analysis assesses 14 different regions along the length of the Y chromosome and will detect all of the microdeletions associated with male infertility, including the AZFa and AZFb/c regions. This analysis exceeds the minimum requirements outlined by the European Academy of Andrology (EAA) and the European Molecular Genetics Quality Network (EMQN).

Limitations of Methodology: Y chromosome microdeletion analysis via PCR will not detect point mutations or small intragenic mutations. Such mutations have been reported but are a very rare cause of male infertility.

Specimen Requirements

Specimen Types:

• Peripheral Blood: 3-4 ml in EDTA (lavender top vacutainer).
• DNA: 3-10 micrograms of DNA suspended in water.  We can only accept DNA isolated in a CLIA-certified laboratory or a laboratory meeting equivalent requirements as determined by the College of American Pathologists and/or the Centers for Medicare and Medicaid Services.
• Saliva: 0.5mL in Oragene•ONE(ON-500) Collection Kit.
