Our expertise in hair testing extends across the nation with facilities ready to conduct hair and alcohol examinations. Generally, 1.5 to 2 inches of crown or body hair is necessary for sampling. Testing options are available for drugs, alcohol/ETG, and other customizable needs.
Recently, many drug testing protocols have incorporated hair follicle analysis over traditional urine tests. This method is favored by employers with zero-tolerance policies, courts, and probation officers due to its extended detection period. A hair follicle test can highlight drug use up to 90 days prior, offering a virtually foolproof collection process. For identifying recent drug use within five days, a urine test remains the most precise.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair analysis is now recognized as a significant method for identifying substance and alcohol consumption. Hair offers an extended timeline of substance and alcohol history by encasing biomarkers within the hair strand's fibers. When taken near the scalp, hair can offer a detection timeframe for substances and alcohol of up to around three months. Hair is straightforward to obtain, relatively challenging to tamper with, and simple to mail.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil's size) closest to the scalp provides 100mg of hair, which is the perfect sample amount for both screening and confirmation processes. For EtG, additional testing, and/or tests exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for specimen measurement. In cases where scalp hair isn't accessible, an equivalent volume of body hair might be used. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key stages in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves registering a sample in a lab’s database initially. This involves verifying the sample's proper sealing and transport, assigning a LAN (Laboratory Accessioning Number), and completing any further data required outside of an electronic chain of custody framework.
Screening is the preliminary rapid assessment for drug abuse. Screening serves as a budget-friendly approach to dismiss drug consumption across most samples; however, confirming a positive screen is necessary for legal admissibility. Samples that are preliminarily positive via Screening need a subsequent confirmation.
If a preliminary positive is obtained during Screening, more hair is extracted from the original sample and prepped for Extraction. This stage involves drug removal from hair at concentrations much lower than alternative methods (e.g., urine or saliva), making hair drug screening a particularly challenging technique to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS is employed for confirming any positive screening outcome. All preliminarily positive samples undergo necessary washes before confirmation. The complete laboratory protocol from Accessioning through Confirmation is scrutinized under CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation.
