In Pegram, TN, Accredited Drug Testing provides thorough hair follicle drug testing. Specializing in this method, our centers nationwide are equipped to conduct hair tests for both drugs and alcohol. A length of 1.5 to 2 inches on the head or body is required. Tests are tailored for drugs, alcohol/ETG, among other options.
Hair follicle drug testing has increasingly become a standard. Preferred by employers, courts, and substance abuse professionals, these tests replace typical urine tests. Employers with zero-tolerance policies, judicial systems, and probationary environments benefit from its extensive 90-day detection window, secure collection, and difficulty in tampering. However, for detecting recent use within five days, urine tests maintain superiority.

Hair testing is now regarded as a significant method for detecting drug and alcohol consumption. Hair can capture a long-term record of alcohol and other drugs by embedding biomarkers in the strands of growing hair. When taken near the scalp, hair offers a detection period of up to 3 months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A hair sample of 1.5 inches, consisting of about 200 strands or the size of a #2 pencil, near the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is suggested. It’s advisable to weigh the specimen using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be used. When we mention head hair, it strictly refers to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a lab system, ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing supplemental data entry missing from an electronic chain of custody system.
Screening provides a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to initially rule out drug use in most samples, any positive result must be confirmed for legal admissibility. Samples testing presumptive positive in Screening need further confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging methodologies.
Positive Screening results go through Confirmation using technologies like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation if required. The full lab procedure from Accessioning to Confirmation is under scrutiny by both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.
