Accredited Drug Testing provides full-spectrum hair follicle drug analysis in Wisdom, Montana. When a hair drug or alcohol test is required, Accredited Drug Testing excels in hair evaluations, with facilities across every city nationwide equipped to execute a hair test. Typically, 1.5 to 2 inches of hair on the scalp or body is needed. Hair assessments are capable of detecting drugs, alcohol/ETG, or other tailored hair testing solutions.
The trend of employing hair follicle drug testing has grown significantly in recent years. Many organizations, judicial bodies, and Substance Abuse experts now favor hair drug tests over conventional urine tests. Hair follicle evaluations are implemented by firms with zero-tolerance drug policies, courts, and individuals on probation. A major advantage of hair follicle testing is its extended drug detection capability—up to 90 days, gathered in a monitored collection process, and nearly tamper-proof. However, for very recent drug use within the last 5 days, urine testing remains the precise choice.

Hair testing is increasingly viewed as an effective means for detecting drug and alcohol consumption. This test captures a long-term drug and alcohol usage history by embedding biomarkers within the hair fiber as it grows. When gathered near the scalp, hair samples can offer a detection period of up to about three months for alcohol and other substances. Collecting hair is straightforward, relatively tamper-resistant, and simple to send.
A hair sample of 1.5 inches in length with approximately 200 strands (equivalent to a #2 pencil's width) nearest to the scalp provides 100mg of hair, which is optimal for both screening and confirming results. For tests such as EtG add-ons or those requiring over 10 panels, a 150mg sample is suggested. Utilizing a jeweler's scale for weighing the specimen is advised. If no scalp hair is accessible, a comparable amount of body hair can be used. "Head hair" refers to scalp hair exclusively, while "body hair" encompasses all other types (like facial or axillary hair).
Process Overview
The primary steps in processing a laboratory hair drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is integrated into the laboratory’s system. This step includes ensuring the sample's seal and shipment integrity, allocating a random LAN (Laboratory Accessioning Number), and accomplishing any required data entry not included in an electronic chain of custody system.
Screening involves an initial rapid assessment for drug abuse. Although it is a cost-efficient approach for excluding drug use in most specimens, any positive result from a screen must be confirmed for court admissibility. Samples with presumptive positive results in the Screening stage need further validation.
When a sample tests presumptively positive during Screening, more hair is procured from the original sample and prepared for Extraction. This phase involves extracting drugs from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), which is why hair drug screening is notably challenging.
Positive screening results are validated using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results undergo washing before confirmation as needed. The end-to-end laboratory process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Limitations:
Note: The term "hair follicle tests" is often used inaccurately; the analysis focuses on the hair strand and not the follicle beneath the scalp.
