Accredited Drug Testing provides comprehensive hair follicle drug analyses in Big Thicket Lake Estates, TX. Whether requiring a hair drug or alcohol exam, we specialize in these tests and maintain facilities nationwide. Typically, 1.5 to 2 inches of hair at the head or body is required. Hair samples can identify drugs, alcohol/ETG, and additional custom testing possibilities.
Hair follicle drug testing has risen in popularity among methods to detect substance use. Employers, judicial systems, and substance abuse practitioners are increasingly choosing hair tests over typical urine analyses. Those with zero-tolerance policies, legal proceedings, and probation services find hair tests indispensable, given their extensive detection window of up to 90 days, collection under supervision, and near-impossibility to falsify. Yet urine tests remain optimal for recent usage detection, particularly within a 5-day span.

Hair testing is viewed as a potent instrument for identifying drug and alcohol usage. Hair captures a detailed and extended history of alcohol and drug consumption through biomarker entrapment in the fibers of the growing hair strand. When sourced near the scalp, hair may reveal up to roughly a 3-month window of drug and alcohol detection. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches of about 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields 100mg, the optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is preferable. It is advisable to weigh the hair specimen using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair may substitute. When mentioning head hair, this exclusively refers to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of results for a drug test comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing phase where a sample is logged into the laboratory’s system. This includes confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included in an electronic chain of custody system.
Screening encompasses a preliminary examination for substance use. Although Screening is a cost-efficient strategy to dismiss drug use for most samples, a positive result requires confirmation for admissibility in legal processes. Samples that screen presumptively positive necessitate additional validation.
If the Screening stage indicates a presumptive positive, additional hair from the original specimen is prepared for Extraction. This step involves drug extraction from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
GC/MS, GC/MS/MS or LC/MS/MS techniques are used for confirming any positive screening outcomes. All samples categorized as presumptively positive are subjected to washing prior to Confirmation as required. The holistic laboratory process, from Accessioning through to Confirmation, adheres to standards under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards of accreditation.
