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