Hair Follicle Drug Testing - Westwood, CA

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. By capturing biomarkers in the strands of hair as they grow, hair offers an extended timeline of alcohol and drug use. A sample collected near the scalp can reveal alcohol and drug usage over roughly three months. Hair sample collection is straightforward, challenging to tamper with, and convenient for shipping.

A sample measuring 1.5 inches, composed of around 200 hair strands (similar to the thickness of a #2 pencil), close to the scalp, yields 100mg, an optimal amount for both initial screening and later confirmation. For EtG add-ons or tests exceeding 10 panels, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale for weighing. In the absence of scalp hair, a proportional quantity of body hair may be used. When mentioning head hair, it exclusively refers to scalp hair, whereas body hair encompasses any other type (such as facial or axillary hair).

Overview of the Process

The core processes of laboratory drug test evaluation include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the lab's framework. This step confirms that the sample was sealed and transported correctly, assigns a random Laboratory Accessioning Number (LAN), and completes additional data input that wasn't recorded by an electronic chain of custody.

Screening offers an initial swift analysis for abuse substances. Despite Screening being a cost-efficient strategy to discern drug use in most samples, a positive result must be verified to be valid in legal proceedings. Samples showing presumptive positives in Screening necessitate further confirmation.

In cases where a sample indicates a presumptive positive during Screening, additional hair is retrieved from the initial sample and prepared for Extraction. Here, drug elements are extracted at concentrations significantly lower than those in other methods (e.g., urine or oral fluids), which renders hair drug testing as a notably complex method to undertake.

Confirmation of any positive screening is performed via methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed before confirmation when necessary. The complete laboratory sequence from Accessioning to Confirmation is scrutinized in accordance with both the College of American Pathologists (CAP) Hair standards and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage up to 90 days, unlike urine tests which have a reduced detection period.
• Challenging to manipulate: Cheating a hair drug test is highly improbable, thereby enhancing result reliability.
• Historical insights: It can illustrate a trajectory of drug consumption over time, rather than just recent indulgence.

Drawbacks:

• Inability to detect recent usage: There's a delay of about 5-7 days before drugs become noticeable in hair strands.
• Expense: Hair drug tests are typically pricier than alternative testing methods.
• Result disparities: Variations in factors like hair color or individual growth rates can influence metabolite concentrations in hair.

Note: While commonly termed as "hair follicle tests", the procedure actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
