Accredited Drug Testing offers comprehensive hair follicle drug testing services in Crescent City, California. Whether for drug or alcohol detection, our specialized centers, available across the nation, can facilitate these tests. Typically, hair samples measuring 1.5 to 2 inches from the crown or body are sufficient for analysis, useful for detecting drugs, alcohol/ETG, or other tailored testing requests.

Hair follicle drug tests have gained popularity in recent times for drug detection. Employers, courts, and Substance Abuse experts often prefer hair tests over standard urine tests. This method is favored by those with zero-tolerance policies, legal systems, and probation departments due to its extended detection window, which covers up to 90 days. Additionally, its observed collection process renders it highly credible, though for recent drug use, urine tests remain the most precise solution.

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures enduring evidence of alcohol and drug use by securing biomarkers within the hair strands as they grow. With a collection near the scalp, hair offers up to about a 3-month detection period for alcohol and drugs. Hair samples are straightforward to acquire, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment containing roughly 200 hair strands (roughly equivalent to a #2 pencil) closest to the scalp can yield 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, and tests over 10 panels, 150mg of hair is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be provided, an equivalent portion of body hair may be used. "Head hair" pertains strictly to scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

There are four essential stages within the laboratory procedure for processing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into a laboratory’s system for initial handling. This step includes confirming that the sample was correctly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and finishing any outstanding data input absent from an electronic chain of custody arrangement.

Screening entails a preliminary assessment to identify drug abuse. Although Screening serves as an economical approach to dismiss drug involvement for most samples, a positive indication requires confirmation to be recognized in legal contexts. Any samples that test as presumptively positive during Screening necessitate a further confirmation.

If a sample yields a presumptive positive outcome during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation of any positive screening outcome is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as appropriate. The complete lab workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair category and the accreditation in compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which feature a briefer detection window.
  • Challenging to falsify: Hair drug tests are particularly resistant to manipulation, ensuring more reliable results.
  • Reveals historical usage: The test can disclose drug use patterns covering an extended timeframe, not merely recent usage.

Limitations:

  • Unable to reveal recent usage: It typically takes 5-7 days for drugs to manifest in hair.
  • Cost: Hair drug tests often incur higher costs compared to other drug screening techniques.
  • Result variability: Elements like hair color and personal variations in hair growth may influence drug metabolite concentrations in hair.

Note: The test, at times labeled as "hair follicle tests", actually examines the hair strand, not the follicle beneath the scalp.
