Along with providing high-quality DNA testing services, DDC offers drug-alcohol testing. This drug-alcohol test can detect when a person misuses drugs or alcohol. The process of the body metabolizing drugs or alcohol produces waste deposits. These deposits are called metabolites and are ingrained in the hair follicle where they can be detected even as the hair continues to grow. The lab can test for these metabolites to get a clear window into the use or abstinence from drugs by that individual.
This type of testing gives a clear historical record of substance misuse, unlike urine or saliva testing that will only show drug use from the prior few days, as hair tends to grow at a quantifiable rate and can be measured.
