Cytogenetics Technologist (Healthcare Professional – Senior to Principal)

Job Summary:

The Colorado Genetics Laboratory (CGL), Department of Pathology, is seeking a full-time (1.0 FTE) technologist at the senior to principal level to join our clinical cytogenetics team. This position performs complex clinical cytogenomic testing utilizing standard and high-resolution chromosome analysis, fluorescence in situ hybridization (FISH) analysis, and chromosomal microarray (CMA) analysis. Responsibilities also include specimen processing for prenatal diagnosis, postnatal constitutional genetic evaluation, and oncology testing to support cancer diagnosis and treatment monitoring.

In addition to performing testing, the technologist may review cases completed by other staff members for accuracy, completeness, and interpretation before Laboratory Director review, as appropriate for the position level. The technologist may also preview cases to ensure the requested testing is appropriate for the clinical indication and specimen received, support laboratory workflow and process decisions, and contribute to efficient laboratory operations.

The technologist participates in quality control and quality assurance activities, supports the development, validation, and implementation of new testing methodologies, and supports continuous improvement as cytogenomic technologies evolve. The successful candidate will adhere to established laboratory procedures, policies, and regulatory requirements while fostering a collaborative, efficient, and mission-driven work environment dedicated to providing high-quality patient care.

Technical Case Review and Interpretation – 25%25

• Performs technical review of completed constitutional chromosome analyses and karyotypes, as authorized based on position level, training, and demonstrated competency.

• Reviews cases for analytical accuracy, completeness, appropriate cell selection, documentation, and correct application of ISCN nomenclature prior to Laboratory Director review.

• Evaluates complex and unusual findings and assists with resolution of analytical discrepancies or review of cases requiring additional workup.

• At the Principal level, provides advanced technical review and consultation for highly complex cases, supports standardization of analytical and interpretive practices, and assists with resolution of difficult or discrepant findings.

Sample Processing and Preparation for constitutional chromosome analysis – 15%25

• Performs specimen processing for constitutional chromosome analysis, including initiation, maintenance, and harvest of cell cultures and preparation of high-quality metaphase cell chromosome slides. Performs specimen processing for FISH and chromosomal microarray (CMA) testing, including DNA extraction, as needed, to support laboratory operations.

• Selects and performs appropriate specimen processing methodologies and techniques to produce high-quality cytogenetic and molecular preparations that meet established laboratory quality standards.

• Contributes to quality control, quality assurance, process improvement, and troubleshooting activities. Recognizes, resolves when appropriate, and communicates processing deviations, equipment malfunctions, or other issues affecting testing quality or workflow.

• Maintains proficiency in sterile technique, cell culture, DNA extraction, laboratory instrumentation, laboratory information systems, and the safe handling and disposal of biohazardous materials and hazardous chemicals.

• Participates in the validation, implementation, and optimization of new cytogenomic testing methodologies, laboratory procedures, equipment and instrumentation, and reagents, as assigned.

Participates in orientation and training – 10%25

• Assists with the orientation and training of new employees, genetics students, residents, fellows, and other healthcare professionals in constitutional chromosome analysis, wet laboratory processing, and established laboratory procedures to promote competency, consistency, and compliance with laboratory standards.

• Provides guidance and technical support to less experienced staff, as appropriate for the position level.
