Hair Testing

A hair test can provide information about what a person is using on a regular basis.  A positive result from a hair sample indicates the frequency of use and/or the use of a large amount of an illegal drug.  

On average, hair grows approximately 1/2 inch per month.  Therefore, each 1/2 inch of head hair can provide a 30 history of drug usage.  The maxium amount of hair we can test with each sample is 1 1/2 inch.  This allows 90 days past drug history to be identified.  Many custody cases request a hair collection for drug analysis.

Bleaches, shampoos, and external contaminants have no impact on the results.

We offer a 6 and 9 drug panel laboratory analysis.  Hair analysis is more costly than urine testing but gives a longer history.  The price we can quote you for hair analysis will still allow this method to be in your range of choice for determining drug choice.  


If you are unsure of what you need, call North Alabama Drug Testing.  We will work with you to determine the best test collection for you.
