Hair Follicle Drug Testing - Fenner, CA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers a detailed history of alcohol and drug use by capturing biomarkers within the fibers of the forming hair strands. When gathered near the scalp, hair can offer up to about a 3-month detection duration for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A 1.5-inch sample comprising approximately 200 strands of hair (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample amount for preliminary screening and confirmation. For EtG, optional add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't obtainable, an equivalent amount of body hair can be gathered. When discussing head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The core steps in the lab processing of a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of processing a sample into a lab's system, which involves ensuring the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data input not supplied by an electronic chain of custody system.

Screening is the preliminary rapid check for drugs of misuse. While Screening is a cost-efficient way to dismiss drug usage in most samples, a positive screen demands confirmation to be valid in a legal setting. Any samples that test presumptively positive during Screening need a follow-up confirmation.

Should a sample be presumptively positive in the Screening phase, further hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are removed from hair at a considerably lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests which have a shorter detection period.
• Challenging to bypass: It is quite challenging to deceive a hair drug test, leading to more reliable results.
• Delivers historical insights: It can illustrate a pattern of drug usage over a timeframe, instead of just recent usage.

Limitations:

• Incapable of detecting recent usage: It requires around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variations: Elements like hair color and personal variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often termed as "hair follicle tests", the actual test examines the hair strand and not the follicle under the scalp
