Hair follicle drug testing is another popular alternative for detecting drug use. The procedure would only require you small sample hair cut from the scalp. This drug testing method can provide a longer window of detection – up to 90 days of donor’s drug use – and has been proven efficient in identifying drug abusers. The hair analysis involves evaluating the amount of drug metabolites embedded inside the hair shaft. This drug test procedure may be done at home or in the workplace.Here at TestCountry, we offer two types of hair follicle drug test kits: self-collection hair test and lab-based hair test. Self-collection hair testing kits are ideal for both parents and employers. They are easy to use and deliver accurate results quickly. The hair samples can be collected at home or in the workplace and are sent in the laboratory using the prepaid priority shipping label provided in the kit. The lab-based hair test option only allows the collection of sample at the lab of your choice. This type is typically used for pre-employment purposes. The hair drug test method is simple and useful if you want to know the history of an individual in the previous 90 days.
