Accredited Drug Testing provides comprehensive hair follicle drug testing services in Guinda, California. When a hair drug or alcohol test is required, Accredited Drug Testing excels in hair testing, operating facilities across all cities Nationwide capable of conducting a hair test. Typically, 1.5 to 2 inches of hair from the crown of the head or body is needed. Hair analysis can detect drugs, alcohol/ETG, or have additional custom testing options.

In recent years, the preference for drug testing methods has increasingly leaned towards hair follicle drug tests. Many workplaces, legal courts, and Substance Abuse experts are opting for hair drug tests over the traditional urine tests. Employers with no-drug tolerance policies, judiciary systems, and individuals on probation utilize hair follicle tests. The main strength of a hair follicle drug test is its extended detection window for drug usage, often up to 90 days, conducted under observation, and virtually tamper-proof. However, for screening recent drug intake within the past 5 days, urine tests remain the most precise.

What it is, How it works

Hair testing has become recognized as a significant method for identifying drug and alcohol consumption. Hair strands store a prolonged timeline of alcohol and drug use by capturing biomarkers within the fibers of growing hair. When taken near the scalp, hair can offer nearly a 3-month detection duration for drugs and alcohol. Hair is effortless to gather, somewhat challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation. For EtG add-ons or tests surpassing 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a similar quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types (such as facial and axillary hair).

Process Overview

The process in a lab for processing a drug test result includes four main steps: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning phase, a sample is initially integrated into a laboratory’s system. This step ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and concludes any extra data entry absent from an electronic custody system.

Screening performs a preliminary swift check for drug abuse. Screening is cost-effective for excluding drug use in most samples, yet a positive screen requires confirmation to be court-acceptable. Samples that presumptively screen positive require a subsequent confirmation.

For samples that appear positive during the Screening phase, additional hair is removed from the original sample and readied for Extraction. At this stage, drugs are extracted from hair at much lower concentrations than in alternative methods (e.g., urine or oral fluid), explaining why hair drug testing is the most challenging method to conduct.

Confirmation of any positive results from screening occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation, as necessary. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug use for up to 90 days, as opposed to urine tests which have a shorter detection span.
  • Hard to falsify: It is extremely challenging to deceive a hair drug test, leading to more reliable results.
  • Provides historical insight: This test can showcase a pattern of drug use over a period, rather than just recent use.

Limitations:

  • Inability to identify recent use: It typically takes 5-7 days for drugs to become detectable within hair.
  • Cost implications: Hair drug tests tend to be more costly than other drug testing techniques.
  • Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests," the test evaluates the hair strand rather than the follicle beneath the scalp
