In Four Points Colonia, Texas, Accredited Drug Testing offers thorough hair follicle drug testing. For those needing hair drug or alcohol evaluations, the company's expertise in hair testing is notable, with facilities available nationwide. Typically requiring 1.5 to 2 inches of hair, these tests can analyze drugs, alcohol/ETG, along with customized options.

In recent years, hair follicle drug tests have gained traction in drug screening. Employers, courts, and Substance Abuse professionals increasingly favor them over traditional urine tests. Employers with strict drug policies, judicial mandates, and probation terms often require it. A key advantage of hair testing is its extended detection window of up to 90 days and its observed collection process, making tampering difficult. Yet, for detecting recent drug use within 5 days, urine tests remain preferable.

What it is, How it works

The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair acts as a long-term record for alcohol and other substances by capturing biomarkers in the hair strand's fibers as it grows. When taken near the scalp, hair can offer a detection window of up to roughly three months for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and uncomplicated to transport.

Gathering a 1.5-inch section of around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the perfect sample size for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a sample of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, the same amount of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The core phases involved in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the primary processing of a sample via a laboratory system. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any other data entry not included by an electronic chain of custody system.

Screening involves an initial, quick assessment for substance abuse. Although Screening is an economical approach to exclude drug use for most samples, a positive screening outcome requires confirmation for legal acceptance. Presumptive positives in Screening need subsequent confirmation.

If Screening yields a presumptive positive, more hair is extracted from the original sample and readied for Extraction. In this phase, drugs are retrieved from hair at lower concentrations compared to alternate methods (e.g., urine or oral fluid), which makes hair drug testing particularly challenging.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair qualification and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug use over 90 days, unlike urine tests with shorter detection periods.
  • Hard to manipulate: Because cheating a hair drug test is exceedingly difficult, outcomes are more precise.
  • Offers historical insights: It delivers a usage pattern over time, not just recent activity.

Limitations:

  • Inability to detect recent usage: It requires about 5-7 days for drugs to be traceable in hair.
  • Expense: Hair drug tests are typically pricier than other testing options.
  • Result variability: Aspects like hair color and personal differences in hair growth can influence the concentration of drug metabolites

Note: Though commonly called "hair follicle tests", the analysis is on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing surpasses urine testing in Four Points Colonia, TX, by offering unmatched detection accuracy and reliability. While traditional urine tests are prevalent, hair tests provide a broader window for identifying substance use.

Extended Detection Window

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

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.
