Accredited Drug Testing offers comprehensive hair follicle drug testing in Woodacre, California. Should you require a hair drug or alcohol test, we specialize in hair testing with facilities across all cities Nationwide capable of conducting such tests. Typically, 1.5 to 2 inches of hair from either your scalp or body is necessary for accurate results. Hair testing options include analysis for drugs, alcohol/ETG, and other bespoke hair testing requirements.

The preference for hair follicle drug testing has surged in recent years. Employers, courts, and specialists in Substance Abuse increasingly choose hair tests over standard urine tests. Hair follicle drug tests serve employers enforcing zero-tolerance drug policies, courts, and individuals on probation. The standout advantage is a significantly extended drug detection period, often reaching up to 90 days, via a monitored process that's virtually foolproof. Still, for recent drug use within five days, urinalysis remains the most precise.

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol usage. Hair encapsulates a historical record of alcohol and drug intake by embedding biomarkers within the growing hair fiber. When taken near the scalp, hair can present a detection span for alcohol and drugs of up to about three months. It is easy to collect, hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches containing roughly 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the preferred amount for initial testing and verification. For EtG, additional panels, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is not an option, an equivalent quantity of body hair can be gathered. "Head hair" specifically means scalp hair, whereas "body hair" includes other hair types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process consists of four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is first introduced into a lab's system, ensuring the sample was intact and sent correctly, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry outside of an electronic chain of custody framework.

Screening involves an expedited initial check for drug substances. Screening is a cost-effective technique to exclude drug use in most samples, but a positive result from Screening must be ratified for it to be acceptable in legal settings. Any samples that show a tentative positive in Screening require a further confirmation test.

Should a sample indicate a positive result during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. At this stage, drugs are separated from hair at a lower concentration than seen in other approaches (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.

Confirmation of any positive screen outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples presumed positive are cleansed before confirmation as necessary. The comprehensive laboratory operation from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection duration: Hair testing can identify drug use for up to 90 days, unlike urine tests that offer a shorter detection period.
  • Hard to manipulate: Cheating a hair drug test is extremely challenging, resulting in more reliable outcomes.
  • Offers historical insight: It reveals a trend of drug consumption over time, not merely recent usage.

Limitations:

  • Cannot indicate recent usage: Drugs become detectable in hair approximately 5-7 days after use.
  • Expense: Hair drug testing generally incurs higher costs than alternative drug testing methods.
  • Result variations: Elements like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests," the examination specifically analyzes the hair shaft, 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.
