Accredited Drug Testing offers comprehensive hair follicle drug assessments throughout Lewisville, Texas. For those needing a drug or alcohol evaluation through hair analysis, our specialized centers afford the expertise required. Numerous nationwide centers stand ready to conduct these tests. Typically, 1.5 to 2 inches of hair from the head or body suffices for testing that identifies drugs, alcohol/ETG, or specific needs.
Recently, utilizing hair follicle assessments for drug detection has grown more popular. More employers, judicial systems, and substance professionals prefer them over regular urine evaluations. Employers with stringent drug policies, courts, and probation officers often require these tests. A standout advantage is the lengthy detection window, typically extending up to 90 days. The observed collection process makes it very hard to tamper with. However, for detecting substance usage inside a five-day span, the urine test remains highly effective.

Hair testing has gained recognition as a strong method for detecting drug and alcohol consumption. Hair can offer a comprehensive history of substance use by encapsulating biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can reveal a detection timeframe of up to three months for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and containing about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample amount for testing and validation. For comprehensive tests beyond ten panels, including EtG tests, it is advisable to use 150mg of the sample. We suggest using a jeweler's scale for weighing the hair sample. If scalp hair isn't available, an equivalent amount of body hair can be utilized. When we mention head hair, it refers specifically to scalp hair. Body hair includes all other forms of hair (e.g., facial, axillary).
Process Overview
The drug testing process in a lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into the lab's system. This stage involves ensuring that the sample is appropriately sealed and shipped, assigning and logging a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drug abuse indications. While this process is cost-effective for eliminating drug use in most samples, a confirmatory test is required for court admissibility. Samples that show presumptive positivity in Screening warrant further confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive screening results is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed prior to confirmation as needed. The laboratory process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
