For those in need of hair drug or alcohol tests, we specialize in hair analysis with facilities available nationwide. Typically, 1.5 to 2 inches of hair from the head or body is required. Hair tests can identify drugs, alcohol/ETG, and offer customized testing options.
Hair follicle drug testing has become more popular in recent years for substance screening. This method is favored by many employers, courts, and substance abuse counselors over traditional urine tests. Hair follicle tests are popular among employers with zero-tolerance policies, probation officers, and legal authorities due to their extensive detection period of up to 90 days and resistance to tampering, although for detecting recent drug use within five days, urine tests remain preferred.

Hair analysis is increasingly recognized for its effectiveness in identifying drug and alcohol consumption. The strands of hair encapsulate biomarkers within their fibers during growth, offering an extended history of substance use. Collected near the scalp, hair can reveal a timeline of approximately three months regarding exposure to alcohol and drugs. Its collection is straightforward, manipulation is relatively challenging, and shipping is convenient.
A segment of 1.5 inches consisting of roughly 200 strands, comparable to a #2 pencil's thickness, can furnish around 100mg of hair, which serves as an optimal quantity for initial screenings and subsequent confirmations. For EtG, additional tests, and arrays beyond 10 panels, collecting 150mg is advisable. Utilizing a jeweler’s scale for weighing is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. References to head hair pertain solely to scalp hair, while body hair encompasses facial and axillary hair types, among others.
Process Overview
The laboratory procedure for drug testing comprises four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample initially enters a laboratory system. This step involves ensuring the sample's proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data input not already provided by an electronic chain of custody mechanism.
Screening involves a preliminary evaluation for substances of abuse. Though cost-effective in negating drug consumption in most cases, any positive result in Screening requires validation to be legally admissible. Samples indicating presumptive positivity in Screening necessitate subsequent confirmation.
In instances of presumptive positivity during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated at concentrations lower than those in other methods (e.g., urine or oral samples), accounting for the complexity of hair drug analysis.
Confirmation of any positive Screening outcomes employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity undergo washing prior to confirmation, when necessary. The laboratory's comprehensive process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and adherence to ISO/IEC 17025 standards.
