Cytogenetic Technologists

What Does a Cytogenetic Technologists Do?

Analyze chromosomes or chromosome segments found in biological specimens, such as amniotic fluids, bone marrow, solid tumors, and blood to aid in the study, diagnosis, classification, or treatment of inherited or acquired genetic diseases. Conduct analyses through classical cytogenetic, fluorescent in situ hybridization (FISH) or array comparative genome hybridization (aCGH) techniques.

Day-to-Day Responsibilities

• 1Arrange and attach chromosomes in numbered pairs on karyotype charts, using standard genetics laboratory practices and nomenclature, to identify normal or abnormal chromosomes.
• 2Count numbers of chromosomes and identify the structural abnormalities by viewing culture slides through microscopes, light microscopes, or photomicroscopes.
• 3Examine chromosomes found in biological specimens to detect abnormalities.
• 4Apply prepared specimen and control to appropriate grid, run instrumentation, and produce analyzable results.
• 5Select appropriate culturing system or procedure based on specimen type and reason for referral.
• 6Analyze chromosomes found in biological specimens to aid diagnoses and treatments for genetic diseases such as congenital disabilities, fertility problems, and hematological disorders.
• 7Harvest cell cultures using substances such as mitotic arrestants, cell releasing agents, and cell fixatives.
• 8Summarize test results and report to appropriate authorities.
