Hair testing shows up substance abuse over a much longer period than other testing methods, with a usual detection window of up to 90 days or more. When a substance is taken the metabolites enter the bloodstream which then pass through to the hair strands.
The main benefits of hair testing are:
- Longer window of detection dependent on hair length
- Detailed data can be provided on a month by month basis
- No requirement for special testing facilities
- Sample taken under Chain of Custody conditions, fully legally defensible
- Confirmation of ‘Non-negative’ samples will be carried out in accordance with ISO17025
- Normal detection window of substances is 5-90 days (drug type dependent)
