What this card shows
The Successful biopsy rate card shows what share of your trophectoderm biopsies came back with a usable genetic result, month by month. The trophectoderm is the outer layer of cells that becomes the placenta, and it is the part sampled for preimplantation genetic testing (PGT).
There are five lines:
Success rate: your monthly rate.
Average for selected period: your rate across the whole date range, drawn as a dashed line.
Competency: the Vienna Consensus competency level, 90%.
Benchmark: the Vienna Consensus benchmark, 95% or above.
# Pending: biopsies still awaiting a response from the genetics lab, as a count on the right-hand axis.
Average for selected period adds up every biopsy with a usable result in the date range and divides by every evaluable biopsy in it, so a busy month counts for more than a quiet one. Biopsies still awaiting the genetics lab are left out of it, as they are from the monthly rate. Compare it with the Competency and Benchmark lines to see where your lab sits over the whole period rather than month by month. It follows every filter at the top of the dashboard.
Reading the card
The success rate is calculated over evaluable biopsies only. A biopsy becomes evaluable once the genetics lab has come back with a definitive answer, which includes an explicit "no result" from a failed or inconclusive test.
A "no result" counts as unsuccessful. That is deliberate: it is a biopsy that consumed an embryo sample and yielded nothing usable.
Biopsies still in flight are excluded from the rate entirely, whatever their age, and shown instead on the # Pending line. This keeps a slow turnaround from dragging your rate down.
Read the two together. The Pending line is a turnaround measure, not a quality one, and a spike in it usually means the genetics lab is behind rather than anything about your biopsies. Recent months normally carry more pending work simply because those results have not come back yet.
The # Pending line uses the right-hand axis, which is a count, not a percentage. The two axes have different scales, so the lines are not directly comparable by height.
The current month is still in progress. Results for biopsies sent in the last few weeks are often still with the genetics lab, so the latest month rests on only the results returned so far and can move a lot as the rest arrive, taking the average with it. For a settled figure, set Date to end at the last full month.
Hover any month to see its exact rate and the average for the period.
The card lives on the Laboratory performance (Vienna consensus KPIs) dashboard, on the Andrology & PGT tab, and responds to the filters at the top:
Date: change the time window. It scopes by the date the biopsy was requested, and defaults to the past 6 months plus the current month.
Clinic: focus on one or more locations, if your organization has several.
Treatment type, Age at cycle start and BMI: narrow to a subset of cycles.
Where this data comes from
Biopsies and their results are recorded against the embryo on the Culture tab of the patient's Cycle page. The biopsy itself creates the record, and the genetic result is recorded against it when the genetics lab responds.
Entering results as they arrive, including the ones that came back with no result, is what moves a biopsy from the Pending line into the rate.
Opening this card
In wawa, open Insights from the sidebar, then go to Standard Reports → Laboratory Performance → Laboratory performance (Vienna consensus KPIs). Select the Andrology & PGT tab. The Successful biopsy rate card is on it.
