A spore test log is read as evidence, so what matters is that each result can be tied to a specific sterilizer, a specific day and a specific load. A log that records only pass or fail per day leaves gaps a reviewer will ask about, and the clinic cannot answer because the information was never written down.
Which fields belong in a spore test log?
The core fields are the date, the sterilizer identifier, the cycle type, the indicator lot number, the incubation start and the result, plus the initials of the person who read it. Each field answers a question a reviewer will ask: which unit, which day, which cycle, which batch, read when, and by whom.
Why does the lot number matter?
The lot number is what connects results to a batch. If a batch is later recalled or turns out to fail more often than expected, the lot field is the only way to find the affected results. Without it, a pattern across a single shipment is invisible.
How should the air-removal test be recorded?
Where the clinic runs a daily pre-vacuum air-removal test, keep it on the same page or a linked page so the day's evidence reads as one sequence. A reviewer should be able to see the air-removal result and the biological result for the same day without searching two systems.
| Field | Example | Question it answers |
|---|---|---|
| Date and time | 14 Oct, 08:20 | When the cycle ran |
| Sterilizer ID | Unit 2 | Which machine |
| Cycle type | Pre-vacuum 134 C | Which programme |
| Indicator lot | Lot A123 | Which batch |
| Incubation start | 08:40 | When reading began |
| Result | Pass | Outcome |
| Reader initials | R. M. | Who verified it |
| Load reference | Tray set 4 | What was monitored |
What makes a log fail a review?
Missing dates, unit names replaced by floor names, results with no reader, and pages that skip days when the clinic was open. Reviewers look for gaps and for records that cannot be tied to a load. A single missing day invites questions about whether the routine is reliable.
How can a clinic make the log easier to keep?
Use a printed form with the required fields rather than a blank book, and keep the same fields across every unit. A log generator produces a consistent page a clinic can print and post beside the sterilizer, and pairing it with a 24-hour rapid readout biological indicator, 50-pack and a 15-well precision dry-block incubator keeps the read time fixed. A BI 5-pack trial (CA $12.99, shipping included) lets staff practise filling the log before live use.

Round Out Your Sterilization Setup
A biological indicator is one link in the chain — these are the pieces it works with:
- Sterilization pouches — Class 4 dual-indicator, 200-pack — the packaging the indicator rides inside
- Autoclave indicator tape — 3-roll set — the external chemical indicator on every pack
- Class 5 chemical integrators — 100-pack — the in-pack check that pairs with your biological indicator
- Sterilization roll — 50 m pre-cut sheets for larger instruments
- Constant-heat pouch sealer — 200 °C, 12 mm seal — for consistent pouch closures
Which format does your sterilizer actually need?
Match the readout time to how fast you need the result: a 24-hour self-contained indicator works in any gravity or pre-vacuum cycle with a standard incubator, while a 3-hour fluorescence tube needs the matching reader. Running one cycle type per day, the 25-pack covers a month; busier clinics move to the 100-pack and cut the per-test cost.
How much do spore tests cost in Canada?
Published pricing runs $3.40 per test on the 25-pack down to $2.99 on the 100-pack — no distributor quote, no account needed.

Frequently Asked Questions
What fields should an autoclave spore test log contain?
Date and time, sterilizer identifier, cycle type, indicator lot, incubation start, result, load reference and the reader's initials, so each result is traceable.
Why is the indicator lot number needed in the log?
It connects results to a batch. If a lot is recalled or shows a pattern of failures, the lot field is the only way to find the affected results.
Should the Bowie-Dick test go in the same log?
Keep it on the same page or a linked page so the day's air-removal and biological results can be read together without searching two systems.
What makes a spore log fail a review?
Missing dates, floor names instead of unit identifiers, results with no reader's initials, and skipped days when the clinic was open.
