What Does ISO Certification Mean for DNA Testing?

ISO certification is more than just a badge — it’s your assurance that we follow strict procedures for quality, security, and environmental responsibility. We currently maintain the following:

• ISO 9001 – Quality Management System
• ISO 27001 – Information Security (essential for handling sensitive genetic data)
• ISO 14001 – Environmental Management

Our commitment to these standards means that every part of the DNA testing process — from enquiry to result delivery — follows strict quality and data protection controls.

UKAS Accredited Laboratory Testing

All of our DNA tests are analysed by a UKAS-accredited laboratory (ISO 17025). This is the gold standard in laboratory testing and ensures that your results are:

• Scientifically validated
• Compliant with UK legal standards
• Accepted for use in legal proceedings if needed

Whether you're using one of our home DNA kits or undergoing a chain of custody DNA test, you can be confident in the reliability of the analysis.

DNA Testing and GDPR Compliance

Both Crystal Health Group and the DNA Clinics brand are fully registered with the Information Commissioner’s Office (ICO), with registration numbers ZA260675 and ZA260357, respectively.

Because DNA is considered special category personal data, we take data protection seriously. Our ISO 27001 certification supports full GDPR compliance for how we collect, process, and store your sensitive information.

Peace of Mind DNA Tests Also Follow ISO Standards

Even if you're using our self-collection DNA kits, such as those sold via our website or the Boots paternity test, your test still benefits from our ISO-certified systems and UKAS lab processing. While legal DNA testing involves stricter chain of custody procedures, the underlying quality and data protection standards are the same across all test types.
