UW Cytogenetic and Molecular Genetic Services


The UW Cytogenetic and Molecular Genetic Services Laboratory is housed within the Wisconsin State Laboratory of Hygiene centrally located in the heart of the University of Wisconsin – Madison campus. Our lab is a clinical diagnostic laboratory providing comprehensive cytogenetic, cytogenomic and molecular genetic testing services for both constitutional (germline) and acquired (somatic) conditions. Our laboratory is certified through the Clinical Laboratory Improvement Act (CLIA), the College of American Pathologists (CAP), and is an active participant of the NCI-sponsored Children’s Oncology Group (COG).


Cytogenetic and Cytogenomic Testing Services

Our lab operates as a full-service cytogenetic testing laboratory, implementing conventional cytogenetic (G-banded chromosome analysis and FISH) and modern cytogenomic (whole genome chromosomal microarray) testing approaches to diagnostics. We provide testing for a range of specimen types including prenatal (amniotic fluid, chorionic villus sampling, products of conception), postnatal (peripheral blood, tissue biopsy), and hematological/oncological (bone marrow, lymph node, solid tumor, FFPE tissue) specimens, among others.

Please refer to our comprehensive testing menu for more details.


Molecular Genetic Testing Services          

Our lab is excited to offer whole exome sequencing services, in addition to targeted molecular genetic testing for a variety of inherited and acquired conditions. Our lab also offers commissioned sequencing services. Our skilled molecular geneticists can work with your team to design customized single and multi-gene Sanger or next-generation sequencing panels, as well as provide variant interpretation.

Please refer to our comprehensive testing menu for more details.

To speak to a lab representative regarding custom sequencing services, please call (608) 262-0402


Education and Research Initiatives

Our lab, like the whole of the University of Wisconsin System, embraces the Wisconsin Idea, a philosophy whereby university research should be applied to solve problems and to improve the health and quality of life for all Wisconsin citizens. As such, our team is always interested in and looking for opportunities to collaborate with UW investigators (and beyond) to drive forward research initiatives and to contribute our genetics knowledge to the greater community.

To learn more about our lab’s educational offerings, please see our Education Section.
