How SCC and CALA Accreditation Affect Sterilization and Contamination Control in Canadian Testing Laboratories

Accreditation questions usually arrive as a purchasing question. A laboratory manager is sourcing specimen containers, sterile tubes or media, and someone in the organisation asks whether the supplier can prove what it sells. The honest answer is that accreditation does not certify a consumable. It certifies the laboratory, and it certifies the processes that decide whether that consumable can be used at all.

What does accreditation actually cover?

Accreditation is granted for a defined scope of testing or calibration work. The certificate names the methods or activities, the site, and sometimes the instruments. Sterilization, cleaning and contamination control are not separate line items. They are supporting processes inside that scope, and an assessor samples them exactly the way a buyer samples a supplier.

Which standard sits behind which programme?

The two laboratory standards share a clause structure that runs from general requirements through to management system requirements, and both put equipment and sample handling in the middle of that structure. That is where sterilization and contamination control live.

Which records does an assessor actually pull?

• Equipment maintenance, calibration and qualification records for sterilizers, incubators and water systems
• Environmental monitoring results, including temperature, humidity or air quality where the method depends on them
• Cleaning and decontamination procedures for equipment that enters or leaves the controlled area
• Reagent and consumable lot tracking, with expiry dates and storage conditions
• Sample handling records that show integrity was protected from receipt to disposal

What does contamination control mean for a testing laboratory?

It means the laboratory has decided where contamination could enter and has controlled those points. Decontaminating equipment before it enters a clean area, controlling the water used in media preparation, and keeping sterile consumables in intact packaging are the everyday version of that decision. A sterile screw-cap specimen container only protects a sample while the packaging is unbroken, which is why the packaging check is a record and not a habit.

How do consumables fit into the quality system?

Consumables are incoming goods. The laboratory has to verify them, store them as the manufacturer directs, and be able to trace which lot was used for which batch of work. A case of graduated sample cups, a rack of sterile centrifuge tubes or a box of 3-wall specimen transport bags all generate the same three fields: lot, expiry and where it went. Suppliers who provide those fields on the case label save the laboratory a transcription step.

What should a purchasing team ask before accreditation?

Ask for the scope, not the logo. Request the certificate number and expiry, then ask which of your own processes the assessor will sample. That answer tells you whether the gap is documentation, equipment records or the consumables sitting in your store room.

Frequently Asked Questions

What is the difference between SCC and CALA in Canadian laboratory accreditation?

SCC is the national standards and accreditation body, and it publishes the accreditation programmes that carry national recognition. CALA is an accreditation body that assesses laboratories against ISO/IEC 17025 and ISO 15189 and publishes a directory of accredited facilities. For a buyer, the working document is the certificate and its scope, not the logo on the website.

Does ISO/IEC 17025 apply to a laboratory that sterilizes its own glassware?

Yes. Clause 6.4 covers equipment, including equipment used to prepare samples and media, so the sterilizer needs a maintenance and calibration record and the sterilization cycle needs a written procedure and result.

How does ISO 15189 treat contamination control?

It treats it as part of the examination process: facilities and environmental conditions, equipment, reagents and consumables, and the handling of samples all have to be controlled and recorded, and the laboratory has to show the records to an assessor.

Can a Canadian laboratory be accredited for sterilization alone?

No. Accreditation is granted for a scope of testing or calibration activities. Sterilization and contamination control sit inside that scope as supporting processes that the assessor will sample.

What evidence does an assessor ask for on consumables?

Lot numbers, expiry dates, storage conditions and the incoming inspection you performed. For sterile items, that means the packaging integrity check you recorded when the case arrived.
