Accredited Drug Testing offers comprehensive hair follicle drug evaluations in Lee Vining, California, catering to those needing hair drug or alcohol testing. Specializing in hair analysis, we provide services throughout the US, capable of conducting hair tests in multiple locations. Generally, 1.5 to 2 inches of hair from either the head or body is required. Hair tests can screen for drugs, alcohol/ETG, and other bespoke testing needs.

The frequency of employing hair follicle tests in drug evaluations has risen lately. Many businesses, judicial systems, and addiction specialists now favor hair tests over the more traditional urine analysis. Hair follicle tests are utilized by companies enforcing strict drug-free policies, legal sectors, and probation monitoring. The key advantage of these tests is their extended detection capability, spanning up to 90 days, with oversight during collection, making evasion difficult. However, for detecting recent drug use within 5 days, urine tests remain the most precise.

What it is, How it works

Hair testing is viewed as an effective method for identifying drug and alcohol consumption. Hair holds a comprehensive record of substance intake by capturing biomarkers within its fibers as it grows. When cut near the scalp, it can offer up to a 3-month timeline of drug and alcohol use. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch section of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg, the optimal amount for analysis and verification. For extended tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing. If scalp hair is not accessible, a comparable amount of body hair may be obtained. When discussing head hair, we mean scalp hair exclusively. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The lab processing of drug test outcomes comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial introduction of a specimen into a lab's system. This involves checking if the sample was sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number) at random, and filling any extra data not given by an electronic custody chain system.

Screening provides a preliminary assessment for drugs of abuse. Though Screening offers a cost-efficient means to exclude drug use in most samples, positive screenings require confirmation for legal validity. Presumed positives from Screening demand additional verification.

Samples suspected to be positive during Screening undergo further preparation for Extraction using hair from the original sample. Here, drugs are isolated from hair at notably lower concentrations than other methods (e.g., urine or saliva), making hair drug testing especially challenging.

All positive results from initial screenings are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Needed presumptive positives are cleaned before validation. The entire lab procedure from Accessioning to Confirmation is governed under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug exams identify substance use for up to 90 days, unlike urine tests, which offer a shorter timeframe.
  • Challenging to manipulate: Hair drug tests are hard to deceive, ensuring more reliable results.
  • Tracks historical use: Reveals a pattern of substance consumption over time, beyond just recent use.

Limitations:

  • Incapable of detecting recent usage: It typically takes 5-7 days for drugs to show in hair.
  • Expense: Hair drug examinations are often pricier than other testing approaches.
  • Result variability: Differences like hair color and individual growth rates can impact the concentration of drug byproducts in hair.

Note: Though frequently called "hair follicle tests," the analysis targets the hair strand rather than 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.
