||Histotechnologists and Histologic Technicians
- Stain tissue specimens with dyes or other chemicals to make cell details visible under microscopes.
- Cut sections of body tissues for microscopic examination, using microtomes.
- 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.
- Prepare or use prepared tissue specimens for teaching, research or diagnostic purposes.
- Arrange and attach chromosomes in numbered pairs on karyotype charts, using standard genetics laboratory practices and nomenclature, to identify normal or abnormal chromosomes.
- Harvest cell cultures using substances such as mitotic arrestants, cell releasing agents, and cell fixatives.
- Prepare slides of cell cultures following standard procedures.
- 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.
||Medical and Clinical Laboratory Technicians
- Prepare standard volumetric solutions or reagents to be combined with samples, following standardized formulas or experimental procedures.
- Collect blood or tissue samples from patients, observing principles of asepsis to obtain blood sample.
- Inoculate fertilized eggs, broths, or other bacteriological media with organisms.
- Obtain specimens, cultivating, isolating, and identifying microorganisms for analysis.
- Cut, stain, and mount tissue samples for examination by pathologists.
||Medical and Clinical Laboratory Technologists
- 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.
- Cultivate, isolate, or assist in identifying microbial organisms or perform various tests on these microorganisms.
- Harvest cell cultures at optimum time, based on knowledge of cell cycle differences and culture conditions.
- 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.
- Draw blood from veins by vacuum tube, syringe, or butterfly venipuncture methods.
- Collect specimens at specific time intervals for tests, such as those assessing therapeutic drug levels.
- Draw blood from capillaries by dermal puncture, such as heel or finger stick methods.
- Collect fluid or tissue samples, using appropriate collection procedures.
- Draw blood from arteries, using arterial collection techniques.
