If seeking a hair drug or alcohol evaluation, Accredited Drug Testing is the go-to expert with centers across various cities in the nation, equipped to conduct hair assessments. Hair measuring 1.5 to 2 inches on the head or body is usually sufficient. Hair tests can screen for drugs, alcohol/ETG or be tailored for specialized evaluations.
Recently, the prevalence of drug testing methods has shifted towards hair follicle tests. A growing number of employers, legal systems, and Substance Abuse experts now request hair drug tests in place of the traditional urine tests. Employers with zero-tolerance policies, judicial systems, and individuals on probation utilize hair follicle tests. The key advantage is a 90-day detection window, collected under supervision, making it extremely difficult to tamper with results. Nevertheless, urinary tests remain superior for detecting substances used within the last five days.

Hair analysis is regarded as an effective method for identifying substance use. Hair captures a prolonged history of substances by encapsulating biomarkers within the strands of growing hair. When taken near the scalp, hair can offer a detection span of up to about three months for substances. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches and containing around 200 hair strands (similar to the thickness of a #2 pencil) taken nearest to the scalp will yield 100mg, which is the perfect quantity for analysis and validation. For EtG, additional tests, and/or assessments above 10 panels, 150mg of the sample is advised. It's best to use a jeweler’s scale for measuring the sample. If scalp hair isn't present, a comparable amount of body hair may be used. By head hair, we are specifically referring to scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory procedure for a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the starting phase of integrating a sample into a lab's system. This step ensures the sample was correctly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and inputs any extra data not included in an electronic chain of custody system.
Screening is an initial swift assessment for drug use. While it is a budget-friendly approach to exclude drug use in numerous samples, a positive result must be confirmed to be valid in legal proceedings. Samples that show a presumptive positive in Screening need a follow-up confirmation.
If a sample is flagged as presumptively positive during Screening, additional hair is extracted from the primary sample for Extraction. During this phase, substances are removed from hair at a much lower concentration than other methods (e.g., urine or oral fluid), signifying the complexity of hair drug screening.
The confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation as required. The whole testing procedure from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Note: Although often called "hair follicle tests," the test analyzes the hair strand, not the follicle beneath the scalp.
