Cytogenetic Technologists

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.

Typical tasks

From O*NET 31.0. Core tasks first. Few of these tasks have a benchmark today.

  • Arrange and attach chromosomes in numbered pairs on karyotype charts, using standard genetics laboratory practices and nomenclature, to identify normal or abnormal chromosomes.
  • Analyze chromosomes found in biological specimens to aid diagnoses and treatments for genetic diseases such as congenital disabilities, fertility problems, and hematological disorders.
  • Prepare biological specimens such as amniotic fluids, bone marrow, tumors, chorionic villi, and blood, for chromosome examinations.
  • Harvest cell cultures using substances such as mitotic arrestants, cell releasing agents, and cell fixatives.
  • Examine chromosomes found in biological specimens to detect abnormalities.
  • Prepare slides of cell cultures following standard procedures.
  • Input details of specimen processing, analysis, and technical issues into logs or laboratory information systems (LIS).
  • Apply prepared specimen and control to appropriate grid, run instrumentation, and produce analyzable results.
  • Evaluate appropriateness of received specimens for requested tests.
  • Summarize test results and report to appropriate authorities.
  • Count numbers of chromosomes and identify the structural abnormalities by viewing culture slides through microscopes, light microscopes, or photomicroscopes.
  • Describe chromosome, FISH and aCGH analysis results in International System of Cytogenetic Nomenclature (ISCN) language.
