Hair Drug Test Cost? 6+ Factors to Know

The expenditure associated with hair follicle drug analysis varies based on several factors. These factors include the testing laboratory selected, the breadth of the drug panel screened for, and the turnaround time required for results. Generally, the price can range from approximately $100 to $200 or more per test. For instance, a standard five-panel drug screen will typically be less costly than a comprehensive screen testing for a wider array of substances.

Hair follicle drug analysis offers a longer detection window compared to urine or blood tests, potentially revealing substance use history spanning up to 90 days. This extended detection period is beneficial in situations requiring a comprehensive assessment of past drug use, such as pre-employment screening for safety-sensitive positions, legal proceedings involving child custody, or substance abuse rehabilitation programs. The method’s ability to identify chronic drug use patterns distinguishes it from other, shorter-term detection methods. Historically, this type of testing has become increasingly reliable and accepted as a forensic tool.
