Accredited Drug Testing offers thorough hair follicle testing for substances in El Verano, California. Those in need of hair alcohol or drug screening can rely on our expertise in hair testing, available at centers across all cities nationally. Typically, hair measuring 1.5 to 2 inches on the head or body is sufficient. Our tests can detect drugs, alcohol/ETG, or be customized for specific needs.

Recently, hair follicle drug testing has become more prevalent in drug screening processes. Many employers, courts, and substance abuse experts prefer hair tests over traditional urine tests. These are ideal for employers with zero-tolerance drug policies, court systems, and those on probation. The key advantage is the extended detection window of up to 90 days, conducted under observation, minimizing the risk of tampering. Nevertheless, for drug use detection within the last 5 days, urine tests remain most precise.

What it is, How it works

Hair testing is perceived as an effective means for detecting drug and alcohol consumption. It provides a long-term record of alcohol and drugs due to the entrapment of markers within the fibers of growing hair. When cut near the scalp, hair offers up to a 3-month timeframe for alcohol and drug detection. Hair samples are uncomplicated to gather, less prone to tampering, and are easy to dispatch.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, extras, and/or panels above 10, 150mg is advisable. It is best to verify the specimen's weight on a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair can be collected. Head hair pertains solely to scalp hair. Body hair covers all other hair types (e.g., facial or axillary).

Process Overview

The process for laboratory analysis of a drug test result consists of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab’s system. This involves ensuring the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not supplied by an electronic chain of custody system.

Screening is a preliminary quick check for drug abuse. Although it is a cost-efficient way to exclude drug use in most samples, a positive result requires confirmation to be court-admissible. Samples that test positive during Screening need further confirmation.

For samples testing positive at the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. During this phase, drugs are retrieved from hair at a lower concentration than other techniques (like urine or oral fluid), making hair drug screening notably challenging.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are cleaned before confirmation as necessary. The complete process from Accessioning to Confirmation is audited under the guidance of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter detection period.
  • Reduced chances of manipulation: It is quite challenging to cheat a hair drug test, enhancing result accuracy.
  • Offers historical insight: It provides an overview of drug usage over time, not only current use.

Drawbacks:

  • Inability to spot recent usage: Drugs appear in hair approximately 5-7 days post-consumption.
  • Expense: Hair drug tests come at a higher cost compared to other testing methods.
  • Inconsistencies: Factors such as hair color and personal differences in hair growth can impact drug metabolite concentration in hair.

Note: Commonly named "hair follicle tests", the analysis targets 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.
