For embryologists
When something in the lab goes wrong, start here.
Every lab troubleshoots by trial and error. This library turns that into a method: start from the problem, work through the likely factors, check each against what the manufacturer actually says — and write it down so it never has to be rediscovered.
Manufacturer-neutral. No endorsements. Always follow the IFU of your own products.
Problem-first guides
3 guidesFertilisation rate has dropped — where to look, in order
A structured way through a sudden fall in 2PN rate after ICSI or IVF: patient mix first, then timing, then the sperm side, then media, oil and dishes, then equipment and technique.
Work through itBlastocyst rate has fallen — separating patient factors from culture problems
When fertilisation is fine but embryos stall between day 3 and day 5: how to tell patient mix from a culture-system problem, and the incubator, media, oil, and handling factors to check.
Work through itPost-warming survival has fallen — vitrification, warming, storage or handling?
When blastocysts stop surviving warming as they should: how to split the problem into the freezing side, the storage side and the warming side, and what to check in each.

CAPA Builder — from what you changed to a finished CAPA
You tell it what you changed and roughly when. From that, it drafts a complete, audit-ready CAPA — a proposed cause for you to confirm, with corrective and preventive actions. Free, like the whole library.
