Hair Follicle Drug Testing - Los Padres, CA

What it is, How it works

Hair analysis is now recognized as a potent method for identifying drug and alcohol consumption. Hair retains a timeline of alcohol and other substance use by locking in markers within its strands as it grows. When gathered near the scalp, hair can indicate drug or alcohol presence for roughly a 3-month period. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch hair sample, roughly the thickness of a #2 pencil and comprising about 200 strands, is required to obtain 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or assessments over 10 panels, it's advised to have 150mg. It's best to weigh this on a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be taken. In this context, head hair refers strictly to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

There are four primary phases in the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step, where a sample is processed into a laboratory system, ensuring the sample was properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and handling any extra data entry not covered by an electronic chain of custody system.

Screening performs a preliminary inspection for drug traces. Though Screening efficiently rules out drug presence in most samples, a positive result requires confirmation to be valid in court. Samples that test presumptively positive in Screening demand subsequent verification.

Should a sample be presumptively positive during Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are pulled from hair at lower concentrations than seen in other techniques (e.g., urine or oral fluid), explaining the high complexity of hair drug analysis.

Any positive findings in Screening undergo Confirmation with GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives are cleaned before Confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is evaluated by CAP (College of American Pathologists) under the Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests may identify drug consumption for up to 90 days, unlike shorter detection intervals seen in urine tests.
• Hard to falsify: Faking a hair drug test is exceedingly challenging, enhancing result reliability.
• Tracks usage history: Offers drug use patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent drug use: Drugs only become detectable in hair about 5-7 days post-consumption.
• Higher costs: Typically more costly than other drug testing options.
• Result variability: Elements like hair color and individual growth rates can influence metabolite concentrations.

Note: Even though sometimes called "hair follicle tests", this test actually examines the hair strand itself, not the follicle beneath the scalp.
