PT samples have to be right. Your laboratory's accreditation is at stake, so anything less than 100% confidence is just not good enough.
That's why we are proud to offer NSI ISO 17034-accredited proficiency testing to Environmental, Food Science, and Cannabis Testing laboratories. Scheduled proficiency tests are available throughout the year. Past report copies and data entry are available 24/7 using the secure online
PT Datalink.
