Training activity information
Details
Analyse, interpret and report the results of cell free DNA screening to include NIPT, and select appropriate reflex tests and prepare interpretive reports for a range of prenatal cases
Type
Developmental training activity (DTA)
Evidence requirements
Evidence the activity has been undertaken by the trainee.
Reflection on the activity at one or more time points after the event including learning from the activity and/or areas of the trainees practice for development.
An action plan to implement learning and/or to address skills or knowledge gaps identified.
Reflective practice guidance
The guidance below is provided to support reflection at different time points, providing you with questions to aid you to reflect for this training activity. They are provided for guidance and should not be considered as a mandatory checklist. Trainees should not be expected to provide answers to each of the guidance questions listed.
Before action
- Do you understand the principles of cfDNA analysis and NIPT, including its sensitivity and specificity for different aneuploidies?
- Are you familiar with the criteria for selecting appropriate reflex tests based on NIPT results and relevant national guidelines?
- What are the key components of an interpretive report for prenatal genetic testing?
- Have you familiarised yourself with the local and national guidelines for cfDNA screening and reflex testing?
- Have you discussed different case scenarios with your training officer to understand potential challenges in interpretation and reporting?
In action
- Pay attention to your actions. How are you currently approaching the analysis of the cell free DNA (cfDNA) screening results, including Non-Invasive Prenatal Testing (NIPT)? Why are you choosing this particular method or sequence of steps for analysis and interpretation?
- What decisions are you making right now as you evaluate the risk scores and fetal fractions? For instance, how are you determining if a result requires a reflex test and which test is most appropriate?
- How effective are your current strategies in identifying potentially high-risk cases and selecting appropriate reflex testing?
- What challenges are you encountering in this moment, such as low fetal fraction, atypical results, or discordant information?
- What can you learn from the data as it unfolds? Are there any unexpected results or patterns emerging that you need to investigate further?
- Are there alternative interpretation approaches you could be considering if the initial results are unclear or if there are discrepancies? For example, could you review the raw data or consider other clinical information?
- What immediate support or guidance might you need if you are uncertain about a specific result, the need for a reflex test, or the appropriate wording for the interpretive report? Would it be beneficial to discuss with a senior colleague or your training officer?
- Are you ensuring that your interpretation and reporting remain within the scope of established laboratory protocols and your level of training and competency?
On action
- Begin by summarising the key aspects of analysing, interpreting, and reporting the cell-free DNA (cfDNA) screening results you worked with.
- What were the key findings of the cfDNA screen in the cases you reviewed?
- What reflex tests did you consider or select, and why? What were the main components of the interpretive reports you prepared?
- What skills or knowledge did you develop or improve in analysing cfDNA screening results, selecting reflex tests, and preparing interpretive reports?
- Were there any unexpected challenges or successes during the activity?
- What did you learn from these, such as difficulties in interpreting borderline results or effectively communicating complex information in the report?
- What areas for continued development have been identified as a result of this activity, such as a deeper understanding of specific cfDNA patterns or refining your reporting skills?
- How can you apply the learning from this activity to your routine practice when dealing with cfDNA screening results?
- Do you need to now review relevant guidelines or discuss challenging cases with a senior colleague to develop further in this area?
- What support or resources might you need to further develop in the areas identified through this reflection, such as access to specific databases or training on complex reporting scenarios?
Beyond action
- Have you revisited the experiences of analysing, interpreting, and reporting cell-free DNA (cfDNA) screening results? Compare your approach and understanding of cfDNA screening now with how it was during this initial training activity.
- Revisit your reflections from this DTA as part of a wider review of the Prenatal Genomics module. What key learning points or actions for development have emerged when considering this activity alongside others?
- How has discussing challenging cfDNA cases or your interpretation strategies with peers or senior colleagues influenced your perspective on these situations?
- How has your ability to select reflex tests and prepare interpretive reports for cfDNA screening evolved since this activity?
- How have you applied the knowledge gained from this DTA in subsequent prenatal cases? Have you developed your skills in communicating cfDNA results or their implications? How has experience since influenced your broader prenatal genomic practice?
- Identify clear actions for the continued development of your skills in cfDNA analysis, interpretation, and reporting in increasingly complex prenatal scenarios.
