Proficiency Testing: The Gold Standard for Reliable Honey Testing at PAQ Laboratories

In the world of honey production and export, accuracy isn't just important, it's everything. Whether you're a beekeeper, packer, or exporter dealing with premium New Zealand honeys like Kanuka or Mānuka, your customers and regulators demand trustworthy results for authenticity, quality markers, and safety parameters.

At PAQ Laboratories in Auckland, we take this responsibility seriously. One of the key ways we ensure our testing is world-class is through proficiency testing. But what exactly is proficiency testing, and why does it matter so much for honey analysis?

What is Proficiency Testing?

Proficiency testing, also known as external quality assessment, is an independent evaluation process where laboratories receive blind samples from a third-party provider. These samples have known (but undisclosed) values for specific analytes. Participating labs test them using their routine methods, submit results, and receive a detailed performance report comparing their outcomes against other participating labs.

Unlike internal quality control, which checks day-to-day consistency within your own lab, proficiency testing provides an external benchmark. It answers the critical question: "Are our results accurate and comparable to the other laboratories in New Zealand?"

Proficiency testing programs are governed by international standards such as ISO/IEC 17043, and they form a mandatory part of laboratory accreditation under ISO 17025, the global benchmark for testing and calibration competence.

Why Proficiency Testing Matters in Honey Testing

Honey is a complex natural product. Testing involves measuring parameters like:

• Quality indicators (HMF, diastase activity, moisture content)

• Authenticity markers (for Kanuka or Mānuka potency, such as specific chemical compounds or AGPs)

• Microbiological safety (APC, yeast and moulds)

• Residues and contaminants

Small variations in methods, equipment calibration, or analyst technique can lead to significant differences in results. In a high-value industry like New Zealand honey, inaccurate testing can affect export compliance, product valuation, and consumer trust.

Proficiency testing helps laboratories:

• Verify accuracy and precision: Confirm that results are not just repeatable internally but align with international standards.

• Identify and correct issues: Detect systematic bias, method weaknesses, or equipment problems early.

• Demonstrate competence: Essential for maintaining or achieving ISO 17025 accreditation, which many buyers and regulators require.

• Build confidence: For clients, knowing a lab regularly participates in proficiency testing means greater assurance in the certificates of analysis they receive.

In honey authenticity testing, where distinguishing genuine Kanuka honey from blends or adulterated products is crucial, proficiency testing ensures methods for detecting unique markers remain robust and reliable.

How Proficiency Testing Works in Practice

1. Sample Distribution: A provider sends identical blind samples to all participating labs.

2. Testing Phase: Labs treat the samples exactly as they would routine client honey submissions with no special treatment allowed.

3. Result Submission: Data is returned within a set timeframe.

4. Statistical Analysis: The provider calculates z-scores or other performance metrics. Satisfactory performance typically falls within acceptable statistical limits.

5. Feedback and Improvement: Labs receive individual reports plus peer-group comparisons. Poor performance triggers root-cause investigation and corrective actions.

At PAQ Laboratories, we proudly participate in relevant proficiency testing rounds. Our team consistently delivers outstanding results, confirming that our methods for honey markers, and quality markers like HMF are performing at a high level. This external validation keeps us "honest, accurate, and ISO 17025-ready."
