Hair Testing

Hair offers a much longer history of drug exposure than any other matrix, therefore, it is an excellent specimen of choice for pre-employment, where the employer needs to know more about drug history than the last few days or weeks. With the exception of marijuana, certain drugs can be found in the hair for 90 days. Hair Testing includes testing of the following drugs:

Marijuana – Cocaine – Opiates – Amphetamines - Ecstasy - PCP
