Accredited Drug Testing provides comprehensive hair follicle drug testing services in Penngrove, California. Specializing in hair analysis for drugs and alcohol, we have centers nationwide ready to perform these tests. Typically, 1.5 to 2 inches of hair from the crown or body is needed. Our hair testing can detect drugs, alcohol/ETG, and other customized substances.

Recently, hair follicle drug testing has gained popularity in screening processes. Employers, legal systems, and substance abuse experts often prefer it over urine tests. Employers with zero-tolerance policies, courts, and probationary programs rely on hair tests due to their extended detection period of up to 90 days, observed collection, and resistance to tampering. For assessing recent drug use, urine tests are still preferred.

What it is, How it works

Hair testing is now recognized as a vital resource for identifying drug and alcohol use. Hair captures a comprehensive timeline of substance intake through the entrapment of biomarkers in the hair's expanding fibers. When taken close to the scalp, it offers up to a three-month detection period for various substances, including alcohol. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.

A hair sample measuring 1.5 inches with approximately 200 strands (comparable to a #2 pencil's thickness) from the scalp provides 100mg of hair, which is the preferred amount for analysis. For EtG, add-ons, or tests beyond 10 panels, a sample size of 150mg is suggested. Using a jeweler’s scale for measuring the sample is advised. If scalp hair is absent, an equivalent quantity of body hair can be used. References to head hair imply scalp hair exclusively, while body hair encompasses all other types (like facial or axillary hair).

Process Overview

The drug testing lab procedure comprises four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initial incorporation into the lab's system. This step confirms the sample was appropriately sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and finalizes any additional information required outside the electronic chain of custody.

Screening provides a preliminary assessment for drugs abuse. Though Screening efficiently excludes drug presence in many samples, any positive screens must undergo confirmation to hold legal standing. Samples showing presumptive positives during Screening necessitate further verification.

Should a sample happen to be presumptive positive at the Screening phase, additional hair from the initial specimen is utilized for Extraction. During Extraction, drugs are retrieved from hair at concentrations lower than other methods (such as urine or oral fluid), highlighting the challenge of performing hair drug screening.

Any positive screening outcomes are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned before confirmation if required. The entire lab procedure from Accessioning to Confirmation is reviewed under both CAP's (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug testing can reveal substance use for up to three months, unlike the shorter duration detectable by urine tests.
  • Hard to manipulate: Cheating a hair drug test is exceptionally difficult, leading to more reliable results.
  • Historical pattern: Hair tests can illustrate a timeline of drug usage, not just recent intake.

Limitations:

  • Not effective for recent use: About 5-7 days is necessary for drugs to become detectable in hair.
  • Expense: Hair drug tests typically cost more than other drug testing methods.
  • Result variations: Elements like hair color and personal differences in hair growth might influence the drug metabolite levels in hair.

Note: While commonly called "hair follicle tests", it's important to note that the test assesses the hair strand itself, not the follicle beneath the scalp.
