Accredited Drug Testing offers comprehensive hair follicle drug assessments in Tara Hills, California. When a hair or alcohol analysis is required, Accredited Drug Testing has expertise in hair evaluations, with Nationwide centers available for testing. Generally, 1.5 to 2 inches of hair from the head crown or body is needed. Tests can detect drugs, alcohol/ETG, or provide other tailored hair testing services.

Recently, drug evaluations have increasingly utilized hair follicle testing. Employers, courts, and Substance Abuse experts now often prefer this method over urine tests. Employers enforcing strict no-drug policies, courts, and probationers frequently choose hair follicle tests. The key advantage is a prolonged drug detection span, typically up to 90 days, with observed sample collection, making it hard to deceive. However, the urine test remains most accurate for drug use detection within the latest 5 days.

What it is, How it works

Hair testing has emerged as a robust method for detecting drug and alcohol usage. The hair shaft offers a prolonged timeline of alcohol and drug presence by incorporating biomarkers into its growing fiber. When samples are cut near the scalp, they may cover up to a 90-day detection period for alcohol and drugs. It's easy to collect, hard to tamper with, and convenient to transport.

A segment measuring 1.5 inches from about 200 hair strands (similar in thickness to a #2 pencil) nearest the scalp yields 100mg of hair, the ideal amount for both screening and confirmation. For EtG tests or when testing above 10 panels, 150mg is advised. We advise using a jeweler’s scale for specimen weighing. If scalp hair isn’t available, an equivalent mass of body hair can be used. When talking about head hair, it solely refers to scalp hair, whereas body hair includes all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial integration into a lab's system. This step ensures the sample is appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finishes any additional data entry not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for drug abuse. While it's a cost-effective method for ruling out drug usage in most cases, a positive screen must be confirmed to hold in legal contexts. Samples presumed positive during Screening require subsequent confirmation.

If a sample is presumed positive during the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. Here, drugs are extracted from the hair at much lower concentrations compared to other methods (like urine or oral fluid), making hair drug screening one of the most complex methods to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug usage up to 90 days, unlike urine tests which have shorter detection periods.
  • Challenge to falsify: It’s very challenging to falsify a hair drug test, ensuring greater accuracy of results.
  • Provides usage pattern: It can offer a timeline of drug use, detailing usage patterns over time, not just recent consumption.

Limitations:

  • Cannot identify recent usage: It generally takes about 5-7 days for drugs to manifest in hair tests.
  • Expense: Hair drug tests tend to be pricier than other methods of drug testing.
  • Result variability: Elements like hair color and individual differences in hair growth can impact drug metabolite concentrations within hair.

Note: Despite being commonly called "hair follicle tests", the examination is conducted on the hair strand, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Tara Hills, CA, hair follicle tests are increasingly preferred over urine tests for their superior detection capabilities. Unlike traditional urine testing, hair analysis identifies substance use with greater precision, reflecting a longer history of drug consumption.
