Accredited Drug Testing offers extensive hair follicle drug testing services in Nevada, Texas. If you require a hair analysis for drugs or alcohol, Accredited Drug Testing is a leader in this field, with facilities across the country ready to conduct hair tests. Typically, 1.5 to 2 inches of hair from the head's crown or body can be used. Hair sampling can identify drugs, alcohol/ETG, or be customized for specific testing needs.
In the past few years, drug testing methods have increasingly adopted hair follicle analysis. Many employers, judicial systems, and substance specialists are opting for hair tests over traditional urine analyses. Hair follicle tests are preferred by employers with strict no-drug policies, by courts, and for those on probation. This test's main advantage lies in its extended window of detection for up to 90 days, conducted under strict observation, making it nearly foolproof. However, urine tests are still superior for identifying drug use within the past 5 days.

Seen as an effective method for identifying drug and alcohol use, hair testing offers a detailed timeline of substance consumption by capturing biomarkers within the fibers of the expanding hair strand. If collected near the scalp, hair can reveal a detection window of up to about 90 days for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch section of roughly 200 strands (comparable to a #2 pencil in width) nearest to the scalp yields 100mg of hair, ideal for screening and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, 150mg of hair is advised. It is suggested to weigh the sample on a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair might be gathered. When discussing head hair, we solely refer to scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four main steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into the lab’s system. This step involves verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not captured by an electronic chain of custody system.
The Screening phase is a preliminary rapid assessment for drug misuse. While Screening efficiently clears negative results for the majority of samples, a positive screen requires confirmation for court usage. Thus, any preliminary positives in Screening need further verification.
If a sample tests presumptively positive during Screening, more hair is drawn from the original sample for Extraction. This phase involves extracting drugs from hair at minute concentrations, unlike other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.
The GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive screening outcomes. All samples marked presumpitvely positive are rinsed before confirmation if necessary. The laboratory procedure from Accessioning to Confirmation undergoes inspection under CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Note: Although commonly termed "hair follicle tests", the examination actually analyzes the hair strand, not the scalp’s hair follicle
