For the lab director
Most fertility EHRs stop at the chart. The embryology record — grades, PGT, straw locations, who witnessed what — ends up in Excel, maintained by the person you can least afford to lose. In Solux the lab record is part of the clinical record, on the same database, under the same audit chain.
Why the laboratory is where the risk lives

Tank, canister, cane, position. "Where is that straw" is one click, not an afternoon with a clipboard and a second pair of hands.
Held on the individual embryo, next to the grade and the time-lapse viability score — not in a PDF attached to the cycle.
Every handling step carries a witness the system requires, and a person is structurally prevented from witnessing their own work.
Which cases used this lot, and which lots touched this case — each one a query, not a search through paper.
Cryo inventory
Tank, canister, cane, straw — and the embryo record attached to the straw rather than filed near it. The drill-down below is a designed view on synthetic data; the real one is on the walkthrough.
Cane 04 · straw positions
Straw 7 · record
Thaw records, disposition decisions and tissue labeling with witness release, against the specimen rather than in a log book.
Register, calibration and PM due dates, tank alarms with an acknowledgement trail, routine QC with supervisory review, proficiency testing.
Competency assessments and credentials with expiry tracking, and the pre-inspection report generated rather than assembled the night before.
Chain of custody
A witnessing rule that depends on someone remembering it is not a control. In Solux the handling step will not save without a second name, and that name cannot be the person doing the work.
Retrieval, fertilization, biopsy, vitrification, thaw, transfer and disposal. The witness is a field the system requires, recorded with a timestamp and a user.
The constraint is in the database, not in training. An embryologist cannot be entered as the witness on a step they performed.
Chain-of-custody events from your witnessing hardware written straight into the specimen record, already built.
Every record change writes a hash-chained entry. A verification routine walks the chain and returns either OK or the exact row where it broke — so you can prove nobody edited the answer afterwards.
Which cases used this media lot, and which lots touched this case. On a recall notice, that is a query you run in front of the person asking.
Holding at double volume
Capacity arguments usually land on the lab as extra risk with no extra staff. This is the part of the platform that makes the volume claim defensible instead of reckless.
Twice the straws, twice the grades, twice the PGT results, and the same file open on two machines. The failure mode isn't a mistake — it's a version.
Volume adds rows, not places to be wrong. Nothing is retyped from the lab into the chart, because the lab entry is the chart entry.
The time your team spends moving results out of the lab's own system and into whatever the clinic reads. At 60 cycles a month that is a working week.
