Accredited Drug Testing in Willow Creek, California offers comprehensive hair follicle drug tests. If a hair drug or alcohol screening is necessary, Accredited Drug Testing is proficient in hair analysis, with centers all over the country that conduct hair tests. A minimum of 1.5 to 2 inches of scalp hair is required, although body hair can be used if needed. These tests can screen for drugs, alcohol/ETG, or can be tailored for other requirements.

Lately, the method for drug screening gradually favors hair follicle drug testing. Numerous employers, courts, and substance abuse experts now prefer hair tests instead of traditional urine tests. This type of testing is favored by employers upholding zero-tolerance policies, judicial systems, and those on probation. The main advantage is its extended detection window, reaching up to 90 days, with a supervised collection challenging to tamper. Yet, for recent drug usage within five days, urine testing remains more precise.

What it is, How it works

Regarded as an efficacious method for detecting drug and alcohol consumption, hair testing captures biochemical markers within the hair fibers over time. When taken near the scalp, hair samples can reflect usage history of alcohol and drugs over roughly a three-month period. The collection process is straightforward, offers resistance to tampering, and lends itself well to transportation.

A hair sample measuring 1.5 inches, consisting of around 200 hairs (about as thick as a #2 pencil) from the scalp area, yields 100mg, the optimal amount for testing accuracy. Additional tests for EtG or beyond 10-panel screenings suggest collecting 150mg. Using a jeweler’s scale for weighing is advisable. If scalp hair cannot be provided, a comparable collection of body hair is acceptable. By head hair, reference is made solely to scalp hair. Body hair includes all other areas (facial, axillary, etc.).

Process Overview

Processing a drug test in a laboratory involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within the laboratory’s system, which involves verifying proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and inputting any supplementary data not included in an electronic chain of custody.

Screening conducts a preliminary evaluation for potential drug presence. Although cost-effective for negating drug use in most samples, only a confirmed positive screen holds legal standing. Samples showing tentative positives in Screening necessitate additional verification.

Specimens with possible positive results proceed to the Extraction phase, which involves pulling more hair from the initial collection. Drugs are extracted from hair at significantly lesser concentrations than other methods (e.g., urine, oral fluid), rendering hair drug analysis particularly challenging.

Confirmation for any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Samples indicating presumptive positivity undergo washing prior to the Confirmation stage when necessary. From Accessioning to Confirmation, the entire lab procedure adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can uncover drug use up to 90 days back, outperforming the shorter duration of urine tests.
  • Hard to manipulate: The difficulty in falsifying hair drug tests enhances result fidelity.
  • Historic usage insights: Offers a record of drug usage trends over time rather than identifying solely recent consumption.

Limitations:

  • Inability to detect recent use: It typically takes around 5-7 days for drugs to become traceable in hair.
  • Higher cost: Generally, hair drug tests incur greater expenses than other drug testing alternatives.
  • Result variability: Variances in hair color and individual differences in hair growth may affect drug metabolite concentrations in hair samples.

Note: Although often termed "hair follicle tests", the procedure analyzes the hair itself, not the follicle below the surface.

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.
Hair testing provides a longer look-back period than urine testing, making it useful when you need to demonstrate ongoing abstinence or identify repeated/recent substance use patterns over time rather than just recent exposure. It is frequently selected for legal, compliance, and custody-related documentation.
A small section of hair is cut by a trained collector in a discreet, controlled manner. The sample is sealed, documented, and sent to the laboratory under established chain-of-custody procedures so that the results can be defended if they are ever challenged.
