Proficiency Testing

We provide proficiency testing schemes with localised support across a truly global network to over 13,000 laboratories in more than 160 countries, conducting over 1,700 proficiency tests each year. Proficiency Testing (PT) is a requirement for accreditation to ISO/IEC 17025 and ISO 15189.


At LGC we operate PT schemes across the food, beverage, environmental, clinical, pharmaceutical, consumer safety, forensic and petroleum sectors – your laboratory will get the support it needs in demonstrating the effectiveness of your quality system.
