After taking a drug, it enters a person’s blood-stream. Next, the drug transfers to the hair follicle, and into the hair strand. As a result, The drug becomes trapped in the hair strand. As the hair strand grows, the drug will move further away from the scalp. Over time, it gets washed away, cut off or falls out.
The Hair Drug Test can detect drugs for a period of up to 12 months. But this does depend on the length of hair that the sample donor has available. 1 cm of head hair will show approximately one month of use.
If no head hair is available, we can test body hair from some areas. The period shown by 1 cm of body hair is approximately 2 to 3 times longer than 1 cm of head hair.
We take in to consideration the time it takes for a drug to move from the blood to the hair follicle. On average, it takes a drug 7 to 10 days to break down in the body and move into the hair strand.
Once the drug has moved from the blood into the hair strand, we detect it using the Hair Drug Test. Also, we can segment hair samples to provide a month by month view of potential drug use. As a result, this can show if someone has recently stopped taking drugs.
Other options are also available for certain circumstances such as spiking incidents. When you call us, a Clinical Advisor can provide details about this service.
