Quality in Dietary Supplements

Certain categories of products that are frequently incriminated (e.g. sexual enhancement, weight management and sports nutrition dietary supplements) are subject to special monitoring to ensure the absence of prohibited pharmaceutical ingredients. In this catalogue, AXIO has summarized all the proficiency testing samples that laboratories may require to meet their proficiency testing requirements. Read on to see our extensive analyte lists – from nutritional testing and element testing, to authenticity and compliance labelling, and the huge range of matrices we offer, from raw materials to finished products.

It is increasingly common for people to supplement their diets with vitamins, minerals, botanicals, or fatty acids to positively affect various aspects of their health. This trend is driving a boom in the supplements industry, but recent scrutiny has also called into question the safety and effectiveness of many of these products. Still too frequently, dietary supplements are in the spotlight for the wrong reasons. These include discrepancies between advertised and actual concentrations of active ingredients, as well as the presence of contaminants and toxic compounds in some products. To better meet the demand for quality and safety, some retailers require their selling partners to verify that their dietary supplement products meet their policy through testing conducted by a third- party testing, inspection and certification organisation.

What is Proficiency Testing?

DRIVING QUALITY TOGETHER

WHAT IS PROFICIENCY TESTING? Proficiency testing (PT) is a mechanism for objectively evaluating a laboratory’s performance by the use of independent external means, and includes regular comparisons of a laboratory’s measurement or test results with those of other laboratories. PT is widely recognised as an essential tool for demonstrating the competence of laboratories, providing the infrastructure for a laboratory to monitor and improve the quality of its routine analytical measurements. PT can provide both evidence of competence and an indication of an underlying or emerging problem.

WHAT SHOULD I CONSIDER WHEN SELECTING A PT SCHEME? Test items Real/simulated materials, properties, concentrations, reporting units. Distribution Frequency, flexible participation, fit for purpose. Reports Speed, language, information, format, evaluation criteria, confidentiality. Participants

National/international, number, methods being used, type of laboratory. Results Deadlines, format, choice of method, reportability of measurement uncertainties, statistical approach. PT provider Scope of PT schemes offered, feedback/assistance provided, quality (accreditation), provision of surplus/ repeat test items.

AXIO | Proficiency Testing schemes 2025

WHAT ARE THE BENEFITS OF PT PARTICIPATION? • Identifying measurement or test problems • Comparing methods or procedures • Comparing operator capabilities • Comparing analytical systems • Improving performance • Verification of method performance • Educating staff • Instilling confidence • Assessing measurement uncertainty • PT test items as internal quality controls

WHAT SHOULD I CONSIDER WHEN INTERPRETING PT RESULTS? Putting performance into wider context • The overall results in the round • Measurement or test method performance • Test item factors • Bimodal result distribution • PT scheme factors Trends in PT performance • Performance over time • Common groups of properties

• Performance of methods • Performance of analysts PT performance errors

• Non-analytical errors – transcription, units, format, calculations • Analytical errors – calibration, methodology, property, sample extraction/clean-up, test items, analyst

ACCREDITATION & PT Proficiency Testing (PT) is a requirement for accreditation to ISO/IEC 17025 and ISO 15189. Using an accredited PT provider gives you assurance in the quality and reliability of the service. LGC is a UKAS (United Kingdom Accreditation Service) accredited proficiency testing provider (ISO/IEC 17043) No. 0001. In addition, we are certified to ISO 9001. The most up-to-date sample data can be found in the Scheme Descriptions and Application Forms.

Local support

LGC AXIO Proficiency Testing is a global leader in proficiency testing solutions, but our teams are local. We support local laboratories, with local PT experts, who can assist in local language. Whether that is needing advice on which PT scheme best meets your requirements, or questions surrounding test results or shipments, we have a team on the ground to support.

Real-world test materials

LGC AXIO Proficiency Testing, where possible, offers real-world samples whose analytical results are comparable with routinely tested samples. AXIO offers the widest range of microbiological organisms, and our analytes are available at a range of concentrations, offering you the closest match to your routine samples.

Investing in your lab’s future

LGC AXIO Proficiency Testing moves with the times, continuing to invest and develop our PT schemes and associated test materials to meet your laboratory’s future needs. This year we have released over 40 new proficiency tests to meet new industry challenges and ever-changing regulatory requirements.

Flexibility in your participation

LGC AXIO Proficiency Testing is proud to supply over 2,700 proficiency tests every year. Many of our test materials are offered multiple times over a 12-month period, and some of our most popular proficiency tests are available up to 12 times a year. This means your laboratory can choose when to participate and at a frequency that suits you.

Flexibility in your reporting

When participating in an LGC AXIO Proficiency Testing scheme, our reporting system PORTAL enables you to submit up to 13 results per analyte, allowing you to compare results between different analysts, methods or instruments. All of the results will receive performance scores, although only 3 nominated results, using different methods, contribute to the statistical analysis.

They provide information about the distribution dates, the sample format, matrices, analytes, and the costs of participation. A Scheme Description is also available, providing technical and statistical information specific to that scheme.

How to join a scheme In order to join a scheme, participants should complete the relevant Application Form, indicating which test materials they wish to receive during the scheme year. Alternatively, the participants can register

Order confirmation Once a participant has joined a scheme, an Order Confirmation will be sent to the requester, which confirms the tests materials selected and distribution dates. Participants can amend an order up to one week prior to the distribution date, subject to test material availability. Any amendments to a participant’s order will be confirmed to them in writing.
