Accredited Drug Testing provides comprehensive hair follicle drug test services in Seven Trees, California. Whether you require a hair drug or alcohol test, we are experts in hair testing, and our facilities are located across the nation to perform such tests. Usually, 1.5 to 2 inches of hair from your head or body is needed. Hair exams can detect drugs, alcohol/ETG, or offer other specific testing solutions.

Over recent years, hair follicle drug tests have become more common in drug screening practices. Many employers, legal systems, and Substance Abuse experts prefer hair tests over traditional urine tests. These tests are utilized by businesses with strict no-drug policies, the judiciary, and individuals under probation. A key advantage of hair tests is their extended detection window, typically up to 90 days, with an observed sample collection that is difficult to manipulate. Nevertheless, urine tests remain most precise for recent usage within the last few days.

What it is, How it works

Hair testing is now recognized as an efficient method for identifying substance use. Hair fibers preserve a lasting record of drug and alcohol use by embedding biomarkers within the strand as it grows. When hair is gathered near the scalp, it can show a drug and alcohol use history of up to roughly 3 months. The collection process is straightforward, resistant to tampering, and easy to transport.

A sample measuring 1.5 inches in length, consisting of about 200 hairs (approximating the thickness of a #2 pencil) and nearest to the scalp, provides 100mg, ideal for analysis. For EtG testing, additional tests, and panels over 10, a specimen weight of 150mg is advised. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be obtained, equivalent body hair may be used. "Head hair" refers exclusively to scalp hair, while "Body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The lab procedures for drug test analysis include Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial sample registration in a laboratory system. This step ensures the sample is properly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number), and fills in any missing information not recorded by electronic means.

Screening involves conducting a basic test for drugs. Though cost-effective and efficient for most cases, a positive screen requires further validation for legal evidence. Positive Screening needs a secondary Confirmation.

If Screening results are positive, additional hair from the initial sample is readied for Extraction. Drugs are extracted from hair at much lower levels compared to other methods (e.g., urine or oral fluid), thus making hair testing the most intricate procedure.

Positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that screen positive undergo a wash before Confirmation if necessary. The lab process, from Accessioning to Confirmation, is reviewed per the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Can identify drug usage up to 90 days versus the shorter timespan for urine tests.
  • Hard to tamper with: Difficult to alter, ensuring more reliable results.
  • Shows usage trends: Offers an overview of drug consumption over time, beyond recent use.

Limitations:

  • Recent use undetectable: Drugs take about 5-7 days to become apparent in hair.
  • Price: Hair drug tests often cost more than other testing forms.
  • Result variability: Factors like hair color and growth rates can influence drug metabolite levels in hair.

Note: Frequently termed as "hair follicle tests," the testing actually evaluates 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.

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.
