Accredited Drug Testing provides comprehensive hair follicle drug screening in Norris Canyon, California. For those needing a test for drugs or alcohol, our specialization covers hair tests, with facilities nationwide. Generally, 1.5 to 2 inches of hair from the scalp or body are required. Our hair analysis can detect drugs, alcohol/ETG, or offer other tailored testing services.

In recent times, the approach to drug assessments has increasingly included hair follicle analysis. A growing number of employers, legal entities, and addiction counselors prefer it over typical urine analyses. Hair analysis caters to workplaces with strict anti-drug policies, court assessments, and probation checks, offering an extended detection timeline up to 90 days. Yet, for drug screening in a 5-day window, urine tests remain unmatched in precision.

What it is, How it works

Examining hair has emerged as an effective method for identifying drug and alcohol consumption. Hair strands capture and retain markers of alcohol and drug use within their fibers, offering a prolonged record that can span several months. When clipped near the scalp, hair can reveal substance use information for up to roughly a 3-month timeframe. Hair collection is straightforward, challenging to tamper with, and easily transportable.

A segment measuring 1.5 inches with approximately 200 hair strands (roughly matching the size of a #2 pencil) taken closest to the scalp delivers about 100mg, which is the optimal quantity for testing and validation. For EtG, supplementary tests, and/or those exceeding 10 panels, a recommendation is set at 150mg of hair. Utilizing a jeweler's scale for weighting the sample is suggested. In the absence of scalp hair, an equivalent amount of body hair is permissible for collection. "Head hair" denotes scalp hair exclusively, while "body hair" implies every other hair type (such as facial, axillary, etc.).

Process Overview

The principal phases in the processing of a drug test sample in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the initial phase of inputting a sample into a lab's framework, encompassing the verification of the proper sealing and shipment of the sample, assigning it a random Laboratory Accessioning Number (LAN), and concluding any pending data entry processes that are not supported by an electronic custody chain system.

Screening serves as a preliminary assessment for drug abuse indicators. Though economically efficient for excluding drug use in most samples, a positive screen requires validation to hold water legally. Samples flagged as potentially positive during Screening necessitate subsequent confirmation.

When a sample tests tentatively positive during the Screening phase, an additional portion is extracted from the original batch and prepared for Extraction. Here, substances are drawn out from the hair at significantly lower levels compared to other techniques (e.g., urine or oral fluid), underscoring the complexity of hair-based drug testing procedures.

Validation of positive screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples presumed positive are cleansed before confirmation, as required. The complete lab cycle from Accessioning to Confirmation receives appraisal under the CAP (College of American Pathologists) Hair designation alongside certification to ISO / IEC 17025 norms.

Advantages of hair drug testing:

  • Extended detection range: Hair drug tests are capable of identifying drug use up to 90 days post-consumption, unlike urine tests which offer a more restricted range.
  • Fraud resistance: Hair drug testing is particularly resistant to manipulation, yielding more trustworthy outcomes.
  • Long-term insights: It highlights trends in drug consumption over an extended timeframe, opposed to merely recent usage.

Limitations:

  • Lack of immediate use detection: Drugs typically need between 5 to 7 days to be traceable in hair strands.
  • Higher expenses: Hair drug tests tend to incur greater costs relative to alternate testing methods.
  • Result disparity: Elements such as individual hair color and growth patterns can influence drug metabolite concentrations in hair samples.

Note: Despite being colloquially called "hair follicle tests", the examination is carried out on the hair strand itself and not the tissue beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
