Accredited Drug Testing offers comprehensive hair follicle drug screening in Yosemite Lakes, California. If you're in need of a hair-based drug or alcohol exam, our specialty lies in hair testing with centers across all cities nationwide to conduct these tests. Typically, you need 1.5 to 2 inches of hair from the head's crown or body. Our hair analyses detect drugs, alcohol/ETG, or offer other tailored hair testing services.

Recently, the trend in drug screenings has shifted towards hair follicle tests. Many employers, judicial systems, and substance abuse experts now prefer these over traditional urine tests. Hair follicle screenings are favored by zero-tolerance employers, courts, and probation officers. Their key advantage is a longer detection window, up to 90 days, with supervised collection, making them hard to manipulate. However, urine tests still excel in identifying recent drug use within five days.

What it is, How it works

The identification of drug and alcohol consumption has been significantly enhanced with hair testing. Hair archives a prolonged timeline of substance usage by embedding biomarkers within the fiber of the hair as it grows. When sourced near the scalp, hair is capable of offering an approximate three-month window of detection for substances. Collecting hair is straightforward, relatively hard to tamper with, and simple to transport.

A sample length of 1.5 inches, typically comprising about 200 hair strands (similar in diameter to a #2 pencil) closest to the scalp will yield 100mg, which is ideal for analysis and verification. For EtG, extended panels, or more than 10 tests, 150mg of the sample is advisable. It's best to measure the sample on a jeweler’s scale. If there's no scalp hair to gather, an equivalent quantity of body hair can be used. We specify head hair as only scalp hair. Body hair denotes all other types (such as facial, axillary, etc.).

Process Overview

The lab handling of a drug testing sample generally proceeds through four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial steps of integrating a sample into the lab system. This encompasses ensuring the sample's proper sealing and dispatch, assigning it a LAN (Laboratory Accessioning Number), and executing any data entry not covered by electronic chain systems.

Screening is a preliminary swift assessment for substance abuse indicators. This step is an economical measure to eliminate drug usage in most samples, yet a positive result from Screening necessitates validation for legal admissibility. Samples that show presumptive positive results in Screening require further validation.

Samples that test presumptive positive during Screening undergo another procedure where additional hair is extracted and prepared for the Extraction phase. During this phase, drugs are separated from hair at minimal concentrations compared to other methods (e.g., urine or oral fluid), making hair testing uniquely challenging.

Confirmation for any presumptive positive results from screening is established through techniques such as GC/MS, GC/MS/MS or LC/MS/MS. Every sample showing presumptive positivity is cleansed before confirmation as necessary. The full process from Accessioning to Confirmation undergoes scrutiny by CAP (College of American Pathologists) Hair specifications and aligns with ISO/IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair tests can flag drug use for up to three months, while urine tests have a narrower detection timeframe.
  • Hard to deceive: Manipulating hair tests is quite challenging, thus enhancing accuracy.
  • Shows usage patterns: Over time, it can reveal drug use trends, not just immediate usage.

Limitations:

  • Does not catch recent usage: Detectable drug presence in hair takes about 5-7 days to manifest.
  • Cost: Hair testing tends to be costlier than other testing methods.
  • Result variability: Elements such as hair color and individual growth rates can influence the metabolite levels in the hair.

Note: Despite being commonly termed as "hair follicle tests", the analysis is conducted on 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.
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.
