Identify historic use with hair strand testing
Hair drug and alcohol testing provides evidence of historic use, covering a period of weeks or months. Both types of analysis offer an overview to determine use, with hair drug testing also available as a segmented analysis to identify trends, such an increase or decrease in use. Our industry-leading method ensures results within four days, ensuring you meet important file-by dates.
77% of social workers surveyed stated that Lextox is their first-choice supplier for hair testing services.
How does hair testing work?
Scalp hair grows at an average rate of one cm per month. This means we can perform a hair test and analyse it for use as far back as the hair strand allows. For example, if a three-month retrospective analysis is required, a three cm section of scalp hair will be used.
When a drug enters the body, it transports via the blood stream and incorporates into the hair follicle. As the hair grows, it incorporates trace amounts of drugs into the hair strand and so we analyse the hair strand for these drug traces.
