Hair Follicle Drug Testing - Irwin, CA

What it is, How it works

Hair testing is now regarded as an effective method for detecting substance and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the hair strand's fibers. When taken from near the scalp, hair can offer up to about a 3-month detection span for alcohol and other substances. Collecting hair is straightforward, relatively tamper-proof, and easy to send off.

A sample measuring 1.5 inches of roughly 200 hair strands (about the girth of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the standard sample size for both screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the specimen is suggested. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair may be utilized. The term "head hair" is solely used for scalp hair, while "body hair" comprises other hair types (such as facial, axillary, etc.).

Process Overview

The primary steps in processing drug test results in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's preliminary entry into the lab's infrastructure. It verifies that the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry that is not included in an electronic chain of custody system.

Screening is an initial rapid evaluation for substances of abuse. While Screening serves as a cost-efficient strategy to exclude drug usage for most samples, results showing a positive screen must be confirmed for legal acceptance. Any samples presumed positive during Screening need a subsequent confirmation.

If a sample indicates potential positivity in the Screening phase, additional hair is extracted from the initial specimen to prepare for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other testing techniques (such as urine or oral fluid), which makes hair drug screening one of the most challenging processes to execute.

Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests with a shorter detection duration.
• High resistance to tampering: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Records historical consumption: It offers a usage pattern over time rather than short-term use.

Limitations:

• Inability to identify recent consumption: It generally takes around 5-7 days for drugs to become detectable within hair.
• Expense: Hair drug tests usually cost more than other testing methods.
• Result fluctuations: Factors like hair color and personal hair growth variations can alter the concentration of drug metabolites in hair.

Note: Commonly known as "hair follicle tests," the analysis targets the hair strand rather than the scalp-situated hair follicle.
