Accredited Drug Testing offers comprehensive hair follicle tests in Clearlake, California. Those requiring a hair drug or alcohol screening will find our specialty in hair testing beneficial, with nationwide centers at your service for all hair examinations. Generally, 1.5 to 2 inches of hair from the head or body is sufficient. Options for hair tests include drugs, alcohol/ETG, or other personalized testing solutions.

In recent times, drug testing frequently incorporates hair follicle screenings. Employers, judicial bodies, and substance abuse experts are transitioning to hair testing from traditional urine tests. These tests cater to employers enforcing zero-tolerance drug policies, court mandates, or probation status checks. A key advantage of hair follicle tests is their extended detection window, which often spans 90 days, collected under direct observation, and resistant to tampering. Nonetheless, for drug use checks within the prior 5 days, urine tests remain top-notch.

What it is, How it works

Hair testing is regarded as a compelling method for identifying drug and alcohol consumption. Hair captures a prolonged record of substances by holding biomarkers in the fibrous structure of the hair strand as it grows. When sampled near the scalp, hair offers roughly a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, resistant to tampering, and convenient to transport.

A 1.5-inch section containing about 200 hair strands (around the girth of a #2 pencil) nearest the scalp yields 100mg of hair, which is the preferred sample quantity for testing and verification. For EtG, additional features, and/or analyses beyond 10 panels, 150mg of the specimen is suggested. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be gathered. When mentioning head hair, it specifically means scalp hair only. Body hair pertains to any other type (facial, axillary, etc.).

Process Overview

The critical stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into a lab’s system. This involves ensuring the sample was appropriately sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and completing any additional required data entry not captured by an electronic chain of custody solution.

Screening consists of a preliminary swift evaluation for substances of abuse. Screening is an economical approach to exclude drug use in the majority of samples, but a positive screening requires confirmation to be permissible in legal settings. Any samples showing presumed positive in Screening require a subsequent confirmation.

If a sample is presumed positive during the Screening phase, additional hair is extracted from the initial specimen for Extraction. During this phase, substances are isolated from hair at a lower concentration than other methods (e.g., urine or oral fluids), making hair drug testing the most challenging method to execute.

Verification of any positive screening outcome ensues using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug tests can identify substance use up to 90 days, unlike urine tests which have a reduced detection duration.
  • Difficulty to manipulate: Cheating a hair test is extremely challenging, enhancing result accuracy.
  • Historical data provision: Reveals a usage pattern over time, not just recent consumption.

Limitations:

  • Unable to detect recent consumption: Drugs typically take 5-7 days to become evident in hair.
  • Expense: Hair drug tests usually cost more than other testing procedures.
  • Result variation: Factors like hair color and personal differences in hair growth may impact metabolite concentration in hair.

Note: Although commonly dubbed as "hair follicle tests", the assessment actually examines the hair strand and 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. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. 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.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
