Hair Follicle Drug Testing - Vine Hill, CA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a detailed history of substance use by embedding biomarkers in the strands during the growth cycle. If taken near the scalp, hair can reveal alcohol and drug usage over a duration of up to three months. It's straightforward to collect, challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (similar in size to a #2 pencil), collected closest to the scalp, provides 100mg of hair, which is the ideal amount for screening and confirmation tests. For EtG, additional tests, or tests over 10 panels, 150mg of the sample is advised. It's recommended to weigh the hair on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair can be taken. When discussing head hair, it refers solely to scalp hair. Body hair includes all other hair types (e.g., facial, axillary, etc.).

Process Overview

The laboratory procedure for a drug test result involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes its first steps in the laboratory’s system. This phase includes ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not covered by an electronic chain of custody system.

The Screening phase provides an initial assessment for drugs of abuse. While Screening cost-effectively excludes drug use in most samples, any positive results need further confirmation to be legally valid. Samples that are presumptively positive in Screening necessitate a secondary confirmation.

For samples showing a presumptive positive result in the Screening stage, additional hair is extracted from the initial sample and set for Extraction. Here, drugs are extracted from hair in much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most complex method to execute.

Confirmation of any positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if necessary. The full laboratory process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug use for up to 90 days, unlike urine tests with a shorter detection span.
• Hard to manipulate: Hair drug tests are extremely difficult to tamper with, which enhances result accuracy.
• Patterns of drug use: It reveals a timeline of drug consumption over time, beyond just recent use.

Limitations:

• Doesn't detect recent use: Drugs become detectable in hair after about 5-7 days.
• Cost considerations: Hair drug tests are typically pricier than some other drug testing methods.
• Result variations: Factors like hair color and personal hair growth differences can impact the concentration of drug metabolites in hair.

Note: Commonly known as "hair follicle tests", these tests assess the hair strand rather than the follicle beneath the scalp
