Hair Follicle Drug Testing - Cedar Hill, TX

What it is, How it works

Hair examinations have emerged as a robust method for detecting alcohol and drug consumption. Hair offers an extended history of drug and alcohol presence by capturing biomarkers within the strands of the hair. Collected near the scalp, hair can present a detection period of approximately 3 months for alcohol and various drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch portion with close to 200 hair strands (resembling the size of a #2 pencil) nearest the scalp shall yield 100mg of hair, optimal for analysis and validation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the sample using a jeweler’s scale. If head hair is not obtainable, an identical amount of body hair may be collected. In terms of head hair, we imply scalp hair alone. Body hair encompasses all other hair varieties (beard, armpits, etc.).

Process Overview

The critical processes in lab handling for drug test results encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the introduction of a specimen into a laboratory system. This involves confirming the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not supplied via an electronic chain of custody system.

Screening encompasses an initial swift examination for commonly abused drugs. Screening serves as an affordable approach to exclude drug use in most samples, but a positive result in Screening necessitates confirmation for legal acceptance. All samples preliminarily positive in Screening demand an additional confirmation.

Should a specimen reveal a presumptive positive outcome at the Screening phase, additional hair from the original sample is readied for Extraction. In this phase, drugs are extracted from hair at notably lower concentrations than other methods (such as urine or oral fluids), demonstrating why hair drug analysis is a challenging methodology to execute.

Confirmation of any positive Screening finding is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes washing before confirmation where needed. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair label and accreditation complying with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection span: Hair drug evaluations identify drug consumption for up to 90 days, surpassing the shorter detection span of urine tests.
• Hard to falsify: Hair drug testing is difficult to deceive, ensuring accurate outcomes.
• Supplies past usage patterns: It can detail drug consumption patterns across time, not merely recent use.

Restrictions:

• Incapable of detecting recent consumption: Roughly 5-7 days are needed for drugs to appear in hair.
• Expense: Hair drug testing is generally costlier than other drug testing forms.
• Result variability: Differences such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp
