An Ontario dental office is expected to run a biological indicator on every day the sterilizer is used, so a daily log is the compliance baseline rather than a weekly one. This walkthrough follows a working week in a two-chair practice and shows what a complete monitoring record looks like, where weekly habits create gaps, and what a College assessor examines. It uses the RCDSO daily expectation as the reference point and separates it clearly from the CDC / AAMI ST79 weekly baseline used in most US states.
What does the RCDSO expect for spore testing?
In Ontario, the RCDSO expects a biological indicator on every day the sterilizer is used — daily monitoring, not weekly. The record should show the date, the sterilizer, the indicator lot, the control result and the incubation outcome. A log that shows only one line per week will not demonstrate monitoring on the other four or five days.
Why does a weekly habit create a documentation gap?
A weekly rhythm leaves four or five days in each week with no monitoring record at all. If instruments were reprocessed on those days, the practice cannot show that the cycle was verified. The gap is a documentation problem even when the sterilizer was working correctly the whole time.
Weekly habits usually start with good intentions. A practice adopts a Monday test because it is easy to remember, and the other four days run on trust. The difficulty is not the test itself; it is that the record no longer matches the days on which instruments were reprocessed, which is exactly what the daily expectation is designed to capture.
How should a dental office organise the daily record?
Use one row per sterilizer per day. Record the date, the unit, the cycle type, the indicator lot number, the incubator control and the result. File the pass result before the first patient load is released, and keep the failed-run procedure on the same page so the response is not left to memory.
A two-chair practice with a single autoclave needs about five rows a week. A practice with a second unit adds a second row for each day both units run. The log should make that doubling visible rather than hide it behind a single weekly entry.
What happens during a College practice assessment?
An assessor reviews the reprocessing log, the training record and the equipment maintenance file together. The questions are practical: how do you know each day's cycle was effective, and what did you do when a test failed. A daily record with a documented response to any failure is the simplest way to answer both.
Training records matter too. An assessor may ask who performs the monitoring and how a new staff member is shown the steps. A short written procedure kept beside the sterilizer, with the log and the incubator, answers that question before it is asked and keeps the routine consistent across staff changes.
| Element | Daily record (Ontario expectation) | Weekly record (CDC / AAMI ST79 baseline in most US states) |
|---|---|---|
| Monitoring days per week | Every sterilizer-use day | One or two |
| Rows per week | 5 to 6 | 1 to 2 |
| Undocumented days | None | Four or more |
| Assessment readiness | Straightforward | Requires explanation |
| Readout options | 24-hour or 3-hour | Same formats |
The practical setup is small: one 25-pack of 24-hour rapid-readout indicators covers about a month in a single-unit office, and a BI 5-pack trial (CA $12.99, shipping included) lets a practice confirm the incubation routine before locking in an annual order. Multi-chair clinics can arrange volume through the wholesale ordering desk. Reselling? become a distributor.

| 24-hour self-contained BI | 100-pack | $299.00 | Order |
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
Does the RCDSO require a spore test every day?
Yes. In Ontario the RCDSO expects a biological indicator on every day the sterilizer is used, so daily monitoring is the working baseline. The weekly frequency is the CDC / AAMI ST79 baseline used in most US states rather than the Ontario rule.
Which fields belong in each log row?
Date, sterilizer identifier, cycle type, indicator lot number, incubator control and result. Keep the corrective action beside any failed row so the response is documented on the same page.
What should a practice do when a test fails?
Quarantine the load, do not release the instruments, review the cycle parameters, retest, and record the corrective action in the log before resuming normal release.
Which readout time suits a busy dental office?
CliniEco supplies 24-hour and 3-hour rapid-readout formats, plus faster 20-minute and 1-hour options when instruments must be returned to circulation quickly.
