Accredited Drug Testing offers comprehensive hair follicle testing services in Dorrington, California. Whether you require drug or alcohol screening, our expertise in hair testing is unmatched, and our facilities span cities Nationwide. Typically, 1.5 to 2 inches of hair from the scalp or body is needed for the test. Hair analysis can detect drugs, alcohol/ETG, or customized testing options.

Hair follicle drug testing has become more prevalent in recent years. Employers, courts, and substance abuse specialists now often prefer it over standard urine tests. It's a popular choice for zero-tolerance employers, judiciary systems, and probationary requirements. Key advantages include a detection window of up to 90 days, direct collection, and reduced chances of tampering. Nonetheless, for drug usage within the past 5 days, urine tests remain most accurate.

What it is, How it works

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. The hair retains a long-term record of alcohol and other substances by capturing biomarkers within the fibers of the growing hair shaft. When gathered near the scalp, hair can offer an estimated 3-month period for detecting alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A 1.5-inch length sample of roughly 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. We advocate using a jeweler’s scale for weighing the sample. If scalp hair isn’t present, a comparable amount of body hair can be collected. When we mention head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The crucial stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within a laboratory’s infrastructure. This step involves ensuring that the sample is appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input not captured by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of misuse. Although Screening is an economical method to exclude drug use in most samples, a positive screen must be confirmed for it to be valid in legal proceedings. Any samples indicating a presumptive positive during Screening necessitate a follow-up confirmation.

Should a sample appear presumptively positive in the Screening phase, extra hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), thus making hair drug screening the most complex method to execute.

Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptive positive are washed prior to confirmation if needed. The complete laboratory process from Accessioning to Confirmation undergoes review under the guidelines of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a more limited detection timeframe.
  • Difficult to manipulate: Cheating a hair drug test is exceedingly difficult, ensuring results are more reliable.
  • Offers historical insights: It can reveal a usage trend over time, beyond just recent consumption.

Limitations:

  • Incapable of identifying recent usage: Drugs take roughly 5-7 days to become detectable in hair.
  • Expense: Hair drug tests tend to be costlier than other drug testing techniques.
  • Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
