Hair Follicle Drug Testing - Chula Vista, TX

What it is, How it works

Assessing substance consumption has become more efficient through hair testing as it uniquely records a prolonged imprint of alcohol and drug usage by embedding chemical markers within the hair fibers as they grow. When hair is gathered near the scalp, it captures a detection duration of up to roughly three months for alcohol and substances. The procedure for collecting hair samples is straightforward, it’s relatively resistant to tampering, and is easy to dispatch.

For accurate examination and validation, a sample of 1.5 inches consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp is needed, amounting to approximately 100mg, which is optimal. For supplementary tests like EtG and/or more than 10-panel tests, it's advised to collect 150mg. Using a jeweler’s scale is suggested for weighing. If scalp hair is absent, a similar quantity of body hair can be utilized. Note that 'head hair' exclusively means scalp hair, whereas 'body hair' encompasses other hair types (such as facial and axillary hair).

Overview of the Process

The drug test laboratory procedure comprises four crucial phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where the sample is introduced into the lab system. It ensures the sample is properly sealed and transported, allocates a random Laboratory Accessioning Number (LAN), and performs any required data input not fulfilled by the electronic custody chain.

The Screening phase provides a preliminary rapid analysis to detect drug abuse. Although this process is cost-efficient for eliminating drug use from most samples, results showing a positive outcome need confirmation for judicial purpose. Samples that are assumed positive in Screening demand secondary validation.

In instances of presumptive positive results during Screening, additional hair is sourced from the original sample to prepare for Extraction. During this stage, drugs are isolated from the hair at significantly lower concentrations than in alternative methods (like urine or saliva), highlighting the technical challenge of performing hair drug analysis.

To substantiate any positive screening outcomes, GC/MS, GC/MS/MS, or LC/MS/MS methods are employed for Confirmation. All samples deemed presumptive positive are cleansed before proceeding to confirmation as required. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP Hair designation and aligns with the ISO / IEC 17025 accreditation standards.

Merits of hair drug examinations:

• Extended detection period: Hair drug examinations can reveal drug use extending up to 90 days, unlike urine tests that possess a much shorter detection span.
• Difficult to manipulate: Manipulating hair drug test outcomes is notably challenging, thus enhancing result accuracy.
• Historical insight: This method offers insight into usage patterns over time, rather than solely focusing on recent consumption.

Drawbacks:

• Lack of immediate detection: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Typically, hair drug examinations incur higher costs compared to other methods.
• Result variations: Factors such as hair color and rates of individual hair growth can alter the concentration of drug residues within the hair.

Note: Commonly termed as "hair follicle assessments," the procedure actually examines the hair strand as opposed to the follicle beneath the scalp.
