Our test types
Hair strand testing
This test provides clear insights into drug use over an indefinite period, while alcohol use can be detected for up to six months. Our segmented analysis reveals patterns over time, providing deeper insight.
Tests are able to detect a wide range of substances with just a small hair sample, it’s quick, non-invasive, and highly accurate.
PEth testing
This test detects alcohol use over the past month with unmatched sensitivity. We now include blood EtG in all PEth tests, which
reveals alcohol intake in the last 2–3 days.
Using a quick and painless dry blood spot test, we eliminate the need for venous blood collection, making the process faster, easier, and just as reliable.
Nail testing
This test provides a detailed, long-term view of drug and alcohol use, detecting substances for up to 6 months, and works by analysing substances trapped in the keratin as the nail grows.
We test for a wide range of drugs, as well as alcohol, offering a reliable alternative when hair testing isn’t possible.
DNA testing
DNA testing provides a fast, reliable way to confirm biological relationships, such as paternity, maternity, or sibling connections.
We use a simple, painless cheek swab to collect DNA, with results available in just a few days. Whether for peace of mind or official matters, DNA testing delivers clear, conclusive answers.
CDT testing
This detects heavy alcohol intake over the past 2-4 weeks by measuring Carbohydrate-Deficient Transferrin, a biomarker affected by sustained alcohol use.
CDT is tested through a venous blood sample and despite being an indicator for regular high alcohol intake, it is most effective when combined with other tests.
Expert report writing
Clear, detailed, and court ready – our expert report writing service provides everything you need to support your case.
Every test we conduct comes with a certificate of analysis, but when you need a more in-depth explanation, our reporting scientists can provide a comprehensive, written, expert report. This includes a formal declaration of results, details on our reporting scientists’ qualifications, and key information about the sample.
Following feedback from family law professionals, we’ve designed our reports to ensure they meet the highest standards and usability.
