In Longview, North Carolina, Accredited Drug Testing offers comprehensive hair follicle drug screenings. For those needing hair or alcohol testing, our specialty lies in hair tests, with centers available in all major cities across the country, ready to conduct hair analysis. Most individuals require 1.5 to 2 inches of hair from the crown or body for testing. We can screen for drugs, alcohol/ETG, or offer personalized hair testing solutions.
Recently, the approach for conducting drug tests has increasingly included hair follicle examinations. This method is gaining acceptance among employers, judicial systems, and Substance Abuse experts who prefer it over urine tests. Employers enforcing zero-tolerance drug policies, judicial entities, and probationers frequently opt for hair follicle tests. Their main advantage is the extended detection timeline, typically up to 90 days; these tests are collected in a supervised setting, making them nearly tamper-proof. Nevertheless, urine tests provide superior accuracy for detecting usage within the previous five days.

Hair evaluation is now recognized as an effective method for identifying the consumption of drugs and alcohol. Biomarkers from alcohol and other substances become embedded in the fibers of the hair as it grows, providing a prolonged record of usage. When taken close to the scalp, hair can offer a detection period of up to around three months for alcohol and other substances. Collecting hair is uncomplicated, not easily tampered with, and convenient to transport.
A sample length of 1.5 inches, comprising about 200 strands of hair (roughly the size of a #2 pencil) proximal to the scalp yields 100mg of hair, which is optimal for evaluation and confirmation. For EtG, extra tests, and/or screenings exceeding ten panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to measure the sample weight. If scalp hair is not available, an equivalent quantity of body hair may be collected. The term head hair denotes scalp hair solely, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The essential steps in laboratory processing for drug test evaluation are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample in a laboratory system. It involves confirming that the sample was appropriately sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any leftover data entries missing from an electronic chain of custody system.
Screening entails a superficial scan for substance abuse. While it is a cost-efficient strategy to exclude substance usage in most samples, a verified positive requires confirmation for admissibility in legal contexts. Any sample that indicates a presumptive positive in Screening necessitates further confirmation.
If Screening suggests a presumptive positive result, more hair is collected from the original specimen for the Extraction phase. Here, the extraction of substances from hair occurs at a considerably lower concentration compared to other methods (such as urine or oral fluids), highlighting the challenge of executing hair drug testing.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples indicating presumptive positivity undergo necessary pre-washing. The comprehensive laboratory workflow from Accessioning to Confirmation is scrutinized in line with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
