Write up an IVD validation
Write the discussion section of an IVD validation report from performance data.
Provide your performance statistics and the applicable CLSI or ICSH guideline, and Anara drafts the discussion section, interpreting each result against the guideline criteria and flagging anything outside acceptable limits. Use it when the study is done and you need regulatory-grade validation documentation.
Prompt
A clinical laboratory scientist validates a new haemoglobin analyzer against the lab's reference instrument.
Prompt
I am writing the discussion section of a laboratory validation report comparing haemoglobin measurement on Analyzer B versus our reference Analyzer A. I have attached the following: (1) a summary of our statistical analysis, including Bland-Altman bias and limits of agreement, Deming regression slope and intercept, and coefficient of variation; (2) the CLSI EP09-A3 guideline.
Write a discussion section for the laboratory validation report covering:
- Summary of the Bland-Altman bias and limits of agreement, interpreted against the guideline's acceptable bias criteria
- Deming regression findings and what the slope and intercept indicate about the relationship between the two analyzers
- Coefficient of variation results, interpreted against acceptable imprecision criteria
- Whether the overall performance supports validation of Analyzer B as a replacement for Analyzer A
- Any parameters outside acceptable limits, stated explicitly with the specific guideline criterion they fail
Use formal laboratory report language throughout. Reference the applicable CLSI EP09-A3 criteria by section for each interpretive statement.What to add to your library
- Required: your performance data summary or raw results, attached or pasted into the chat.
- Required: the applicable guideline or standard, such as CLSI EP09, CLSI EP15, ICSH, or ISO 17025.
- Optional: a discussion section from a prior report, so Anara matches your lab's language conventions.
- Optional: the clinical context for the analyte, such as diagnosis versus monitoring.
What you get
- A formal discussion section covering each performance dimension you named.
- Each interpretation tied to the guideline criteria by section.
- Any parameter outside acceptable limits named explicitly, with the criterion it fails.
Follow-ups
Draft the conclusions section.
Prompt
Based on the discussion section you just wrote, draft the conclusions section for the validation report. State whether Analyzer B is validated for clinical use as a replacement for Analyzer A, with a one-sentence justification for each performance dimension assessed.Apply the same structure to a second analyte.
Prompt
The same validation run also assessed mean corpuscular volume. Here are the MCV statistics: [paste statistics]. Apply the same discussion structure to MCV, using the same guideline and the same formal report language.Tips
- Name the exact guideline, such as "CLSI EP09-A3." If you used several (EP09 for comparison, EP15 for precision), list each.
- Ask for out-of-limit parameters to be stated explicitly. Softened language can fail regulatory review.
- Anara does not recalculate your statistics. Check the draft against your data tables.
