Hair Follicle Drug Testing - Forest Meadows, CA

What it is, How it works

Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair offers an extended timeline monitoring alcohol and drug use by embedding biomarkers in the hair strand's fibers. When sampled near the scalp, hair can provide a detection window of up to approximately three months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weight of 150mg is advised. We recommend utilizing a jeweler’s scale for weighing the sample. If scalp hair is not available, an equivalent amount of body hair may be utilized. When mentioning head hair, this pertains solely to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The four primary steps in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample within a laboratory’s system. This entails verifying that the sample remains sealed and has been properly shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening involves a preliminary assessment for drugs of abuse. While Screening provides a cost-effective means to rule out drug use in most samples, any positive screen must be confirmed for court acceptability. Samples that are presumptively positive in Screening necessitate a secondary confirmation.

In cases where a sample is presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations than seen in other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology.

Confirmation of any positive screening result is accomplished using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Resistant to cheating: Hair drug tests are very challenging to manipulate, resulting in more reliable outcomes.
• Offers historical insight: They can demonstrate drug usage patterns over time, rather than solely recent usage.

Limitations:

• Incapable of recent detection: Detection of drugs in hair takes approximately 5-7 days.
• Expense: Hair drug tests are typically more costly than alternative drug testing methods.
• Result variances: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis examines the hair strand and not the hair follicle beneath the scalp
