- Count numbers of chromosomes and identify the structural abnormalities by viewing culture slides through microscopes, light microscopes, or photomicroscopes.
- 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 birth defects, fertility problems, and hematological disorders.
- Examine chromosomes found in biological specimens to detect abnormalities.
- Prepare slides of cell cultures following standard procedures.
- Recognize and report abnormalities in the color, size, shape, composition, or pattern of cells.
- Prepare biological specimens such as amniotic fluids, bone marrow, tumors, chorionic villi, and blood, for chromosome examinations.
- Extract, measure, dilute as appropriate, label, and prepare DNA for array analysis.
- Select or prepare specimens and media for cell cultures using aseptic techniques, knowledge of medium components, or cell nutritional requirements.
- Stain slides to make chromosomes visible for microscopy.
||Histotechnologists and Histologic Technicians
- Stain tissue specimens with dyes or other chemicals to make cell details visible under microscopes.
- Mount tissue specimens on glass slides.
- Embed tissue specimens into paraffin wax blocks or infiltrate tissue specimens with wax.
- Freeze tissue specimens.
- Perform procedures associated with histochemistry to prepare specimens for immunofluorescence or microscopy.
- Identify tissue structures or cell components to be used in the diagnosis, prevention, or treatment of diseases.
- Prepare or use prepared tissue specimens for teaching, research or diagnostic purposes.
||Medical and Clinical Laboratory Technicians
- Conduct chemical analyses of body fluids, such as blood or urine, using microscope or automatic analyzer to detect abnormalities or diseases and enter findings into computer.
- Prepare standard volumetric solutions or reagents to be combined with samples, following standardized formulas or experimental procedures.
- Inoculate fertilized eggs, broths, or other bacteriological media with organisms.
- Obtain specimens, cultivating, isolating, and identifying microorganisms for analysis.
- Examine cells stained with dye to locate abnormalities.
- Cut, stain, and mount tissue samples for examination by pathologists.
||Medical and Clinical Laboratory Technologists
- Conduct chemical analysis of body fluids, including blood, urine, or spinal fluid, to determine presence of normal or abnormal components.
- Collect and study blood samples to determine the number of cells, their morphology, or their blood group, blood type, or compatibility for transfusion purposes, using microscopic techniques.
- Analyze samples of biological material for chemical content or reaction.
- Cultivate, isolate, or assist in identifying microbial organisms or perform various tests on these microorganisms.
- Select and prepare specimens and media for cell cultures, using aseptic technique and knowledge of medium components and cell requirements.
- Obtain, cut, stain, and mount biological material on slides for microscopic study and diagnosis, following standard laboratory procedures.
- Examine microscopic samples to identify diseases or other abnormalities.
- Conduct genetic analyses of deoxyribonucleic acid (DNA) or chromosomes to diagnose small biopsies and cell samples.
