Located in Forks of the River, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug assessments. Whether it's for drugs or alcohol, our specialization in hair analysis is supported by our nationwide network of facilities capable of conducting such tests. Generally, a hair length of 1.5 to 2 inches from the scalp or a body source is sufficient, enabling us to analyze for substances including alcohol/ETG or customize as needed.
Lately, hair follicle assessments have become a staple in drug testing methodologies. A growing number of employers, judicial bodies, and Substance Abuse experts now opt for hair drug evaluations over typical urine exams. These tests are chosen by businesses upholding strict drug-free policies, legal entities, and probationers. Their principal advantage lies in detecting drug use over a longer span—up to 90 days—collected under supervised conditions and remain mostly tamper-proof. However, monitoring drug use within a recent 5-day window still favors urine testing for accuracy.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history by embedding biomarkers in the strands as they grow. Collected near the scalp, hair can offer an approximately 3-month window for detecting alcohol and drug use. Collecting hair is straightforward, is relatively tough to tamper with, and is easily transportable.
A sample of 200 hair strands at a length of 1.5 inches (about the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, a specimen of 150mg is suggested. It’s advisable to weigh the specimen using a jeweler's scale. If scalp hair isn’t available, the same amount of body hair can be used. The term head hair specifically means scalp hair, while body hair covers other varieties (facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample in a lab’s system. This step involves ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry that the electronic chain of custody didn’t cover.
Screening involves a quick, initial check for substances. While it’s a budget-friendly method for excluding drug use on most samples, a positive screen must be verified before it becomes court-admissible. Samples deemed presumptively positive during Screening need a secondary confirmation.
If Screening suggests a sample is positive, additional hair is taken from the original specimen for Extraction. Drugs are extracted at lower concentrations from hair compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation for any positive screen result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation, as necessary. The entire lab procedure from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and follows accreditation standards of ISO / IEC 17025.
