In San Gabriel, CA, Accredited Drug Testing provides extensive hair follicle drug testing services. Should you require a test for drugs or alcohol through hair samples, our expertise lies in hair assessments, with testing locations across the nation. Generally, 1.5 to 2 inches of hair from the head or body suffices for testing. Options include analysis for drugs, alcohol/ETG, or personalized testing solutions.

Hair follicle drug tests have increasingly become a standard method for detecting drug use. Courts, employers, and professionals in substance abuse settings prefer them over traditional urine tests. Zero-tolerance workplaces and those on probation find them beneficial for their prolonged detection window—up to 90 days. The process is supervised, reducing tampering risks. However, for drug detection within five days, urine tests still retain superior accuracy.

What it is, How it works

Hair evaluation has emerged as an impactful means for identifying drug and alcohol consumption. Hair captures long-term histories of alcohol and drug use by confining biomarkers within the strands of growing hair. When taken near the scalp, hair can offer up to roughly a three-month window for spotting alcohol and drug consumption. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment from around 200 strands of hair (roughly matching a #2 pencil's width) nearest to the scalp will yield 100mg of hair, optimal for screening and validation. For EtG, additional substances, and/or evaluations exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample on a jeweler's scale. If scalp hair is not present, a similar amount of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair alone. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory workflow of generating a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the foundational handling of a sample into a lab’s infrastructure. This includes ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening functions as the preliminary swift assessment for drugs of misuse. Although Screening is an economical means to exclude drug use in most samples, a positive screen must be substantiated for acceptance in legal contexts. Samples indicated as presumptively positive in Screening necessitate subsequent confirmation.

Should a sample be tentatively positive in the Screening phase, additional hair is drawn from the original specimen and readied for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which renders hair drug screening the most challenging technique to execute.

Verification of any positive screening outcome is executed through GC/MS, GC/MS/MS or LC/MS/MS. All samples indicated as presumptively positive undergo washing before confirmation as required. The full laboratory sequence from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection timeframe: Hair drug testing can reveal drug consumption for up to 90 days, whereas urine tests provide a shorter detection timeframe.
  • Challenging to falsify: Tampering with a hair drug test is extremely challenging, leading to more precise outcomes.
  • Offers historical insight: It can outline drug use trends over a given period, rather than just capturing recent consumption.

Limitations:

  • Incapable of detecting recent consumption: Drugs become noticeable in hair approximately 5-7 days post-use.
  • Expense: Hair drug testing tends to be pricier compared to alternative drug testing techniques.
  • Result variations: Variables like hair color and personal differences in hair growth can impact the concentration of drug metabolites in hair.

Note: While commonly termed "hair follicle tests", the procedure scrutinizes the hair strand and does not pertain to the hair 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.
