Can hair collected from a hairbrush be used?
No, we do not recommend taking a hair sample from a brush or any other source (e.g. pillow, clothing) as the sample may be contaminated and there is no guarantee that the hair is from the person being tested. Additionally, this would destroy any legal validity of the test results as proper chain of custody could not be established. If the test results are for solely for informational purposes only and not intended to be used legally (e.g. Parent testing their child). and further that the above risks are acceptable, hair taken from a hairbrush may be tested as long as the sample quantity and length is sufficient as specified in the test instructions. However, it must be stated clearly that the laboratory may reject a hair sample if it is not collected and prepared as per the test instructions. No refunds are available if the laboratory rejects the sample.
