Accredited Drug Testing offers comprehensive hair follicle drug testing in Cedar Hill, Texas. For those requiring a hair drug or alcohol test, Accredited Drug Testing excels in conducting hair tests, with centers nationwide equipped to perform these tests. Typically, 1.5 to 2 inches of hair from the head or body is sufficient for testing. Hair tests can detect drugs, alcohol/ETG, or customized testing configurations.

Recently, the use of hair follicle drug tests has surged. Employers, courts, and substance abuse specialists are increasingly opting for hair drug tests over standard urine tests. Businesses with zero-tolerance drug policies, courts, and probation departments employ hair tests due to their extended detection period of up to 90 days, which are gathered in supervised conditions, making them difficult to falsify. For recent drug use within the last 5 days, urine tests remain highly precise.

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

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
Hair testing provides a longer look-back period than urine testing, making it useful when you need to demonstrate ongoing abstinence or identify repeated/recent substance use patterns over time rather than just recent exposure.
