Should you need a hair drug or alcohol test, Accredited Drug Testing excels in hair analysis and has facilities across all cities Nationwide equipped to carry out such tests.

Hair follicle drug testing has increasingly become the preferred method for drug screening in recent years. Employers, judicial systems, and Substance Abuse experts often favor this over traditional urine testing. Those enforcing zero-tolerance drug policies, the judiciary, and probation services opt for hair follicle testing due to its prolonged detection period, generally up to 90 days, conducted under close supervision, making it almost tamper-proof. However, for detecting recent drug use within a five-day window, urine tests remain the gold standard.

Hair analysis has emerged as a powerful method for detecting drug and alcohol consumption. Hair offers a prolonged history of alcohol and drugs by capturing biomarkers within the strands of growing hair. When obtained near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment of around 200 hair strands (roughly #2 pencil thickness) nearest to the scalp will yield 100mg of hair, which is the ideal sample size for both screening and confirmation. For EtG, supplements, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale for weighing. If scalp hair isn't available, an equivalent amount of body hair might be used. When addressing head hair, we refer solely to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system, ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not included by an electronic chain of custody setup.
Screening comprises a preliminary rapid assessment for substances of abuse. It is a cost-efficient way for most samples, but screen positives must be confirmed for legal admissibility. Samples preliminarily positive in Screening necessitate secondary confirmation.
For presumptive positives in Screening, further hair is extracted from the original sample for Extraction. Drugs are extracted from hair at lower concentrations than other techniques (ex. urine or oral fluid), explaining why hair drug screening is challenging to execute.
Positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples are washed before Confirmation if necessary. The entire process is evaluated under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
