Accredited Drug Testing provides comprehensive hair follicle drug assessments in Lakeport, California. If a hair-based drug or alcohol test is required, we excel in hair testing and offer locations nationwide, including all cities, for hair tests. Generally, 1.5 to 2 inches of hair from the scalp or body is required. These tests can detect drugs, alcohol/ETG, or customized testing options.

Recently, the hair follicle drug test has become a favored method for conducting drug assessments. Numerous employers, judicial systems, and Substance Abuse experts now require hair drug testing instead of the traditional urine analysis. Hair tests are preferred by employers with zero-tolerance drug policies, the courts, and probationary services. The primary advantage is the extended detection window for drug usage, often up to 90 days, conducted under observation, and hard to manipulate. Nonetheless, for checking drug use within the past 5 days, urine testing remains the most accurate.

What it is, How it works

Viewed as a potent method for identifying drug and alcohol consumption, hair testing uses the hair strand's fibers to capture drug and alcohol biomarkers, offering an extended overview. When collected near the scalp, hair can indicate drug and alcohol use over roughly a three-month period. The collection process is straightforward, challenging to tamper with, and facilitates easy shipping.

Gathering a 1.5-inch sample, roughly 200 strands (similar to a #2 pencil's thickness), closest to the scalp yields 100mg, which is the perfect amount for analysis and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a sample size of 150mg is advisable. It's suggested to measure the sample with a jeweler's scale. In cases where scalp hair isn't accessible, a comparable quantity of body hair might be used. References to head hair pertain solely to scalp hair. Body hair encompasses other types like facial and axillary hair.

Process Overview

The procedure for processing a drug test result in the laboratory includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning phase, a sample is initially processed into the laboratory system, ensuring the sample seal and shipping were proper, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry not supplied by an electronic chain of custody system.

In the Screening stage, a quick preliminary check detects substance misuse. Though Screening is a budget-friendly method to exclude drug usage in most samples, a positive result requires further confirmation for legal acceptability. Any samples that indicate a potential positive in Screening need secondary verification.

Should a sample show a potential positive during the Screening phase, more hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted at remarkably lower concentrations than other methods (e.g., urine or oral fluid), which renders hair drug testing as the most challenging to conduct.

Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every sample that tests presumptively positive is cleansed before confirmation, as necessary. The entire laboratory process, ranging from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards compliance.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can uncover drug use for up to 90 days, whereas urine tests have a shorter span.
  • Cheating is arduous: Tampering with hair drug tests is exceptionally difficult, ensuring higher result accuracy.
  • Historical usage pattern: It tracks drug usage patterns over time, not just recent consumption.

Limitations:

  • Inability to detect recent consumption: Drugs need approximately 5-7 days to appear in hair.
  • Expense: Hair drug tests typically incur higher costs than other testing methods.
  • Result fluctuation: Variables like hair color and individual growth rates impact drug metabolite concentrations in hair.

Note: Although occasionally termed "hair follicle tests", the analysis is conducted on the hair strand and not on 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.
