Accredited Drug Testing provides extensive hair follicle drug testing services in Crawford, Tennessee. If a hair drug or alcohol test is needed, Accredited Drug Testing excels in hair testing and has centers in all cities nationwide that can perform it. Typically, 1.5 to 2 inches of hair from the head or body are required. Hair tests can detect drugs, alcohol/ETG, or other specialized options.
In recent years, the hair follicle drug test has become more prevalent in drug testing. Employers, courts, and substance abuse experts increasingly favor hair drug tests over urine tests. Hair tests are preferred by employers with zero-tolerance policies, courts, and probation individuals. Hair follicle tests offer a longer detection timeline, up to 90 days, are collected under supervision, and are nearly impossible to rig. For recent drug use within five days, urine tests remain most accurate.

Hair testing is now acknowledged as an effective method for identifying drug and alcohol use. Hair captures a long-term record of these substances, embedding biomarkers within the hair strand fibers as they grow. By obtaining hair close to the scalp, one can achieve roughly a three-month window for detecting alcohol and drug presence. Collection of hair is straightforward, with minimal alteration risk, and is convenient for shipping.
A 1.5-inch section of approximately 200 hair strands (comparable in thickness to a #2 pencil) near the scalp yields about 100mg of hair, which is the optimal quantity for both screening and confirmation. For tests exceeding 10 panels, EtG, or additional add-ons, it's advised to gather 150mg of the sample. Using a jeweler’s scale to weigh the sample is recommended. When scalp hair is inaccessible, an equivalent amount of body hair can be used. The term head hair refers specifically to scalp hair, while body hair encompasses all other hair types such as facial or axillary hair.
Process Overview
There are four foundational steps in processing a drug test result at the laboratory: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing in the lab’s system. This step involves checking the sample's proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and finalizing any additional data entries absent from an electronic chain of custody system.
Screening consists of an initial expeditious assessment for drug misuse. Although Screening is a cost-efficient method to rule out drug use in most cases, any positive findings require confirmation to be legally valid. Any samples that test presumptive positive in Screening necessitate further confirmation.
If a sample returns a presumptive positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. This phase involves separating drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluids), making hair drug testing one of the most complex methodologies.
Confirmation of any positive results during Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are washed before confirmation as deemed necessary. The entire process, from Accessioning to Confirmation, is examined per the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite the common term "hair follicle tests," the analysis focuses on the hair strand itself rather than the follicle beneath the scalp.
