Hair drug testing detects a lifestyle of drug use as opposed to one-off or infrequent use. Since a bloodstream feeds hair growth, TDDA can assist in detecting drug use by analysing a small sample of hair.
Benefits of hair drug testing
- Hair samples cannot be substituted or diluted, and therefore difficult to adulterate
- Long detection timeframe—90 days being the standard testing timeframe
- Collection is safe and simple
- Flexible collection: while head hair is preferred, body hair can also be used
- Results are not affected by external contaminants
- Detection period is only dictated by the length of hair available
- Results are admissible in court

Why choose TDDA’s hair drug testing services?
TDDA’s hair testing process, which features a robust internal chain of custody, is modelled after US federal guidelines published by The Substance Abuse and Mental Health Services Administration (SAMHSA), as well as that of other accrediting agencies, such as the College of American Pathologists (CAP).
The US-based laboratory TDDA utilises follows cut-off levels generally accepted industry-wide. Once samples are received at the lab, a report is produced within 1-3 business days.
