Hair Follicle Drug Testing - San Ysidro, NM

What it is, How it works

Hair testing has emerged as a potent instrument for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug usage by embedding biomarkers within the fibers of the hair strand. When sourced near the scalp, hair can offer up to an approximate 3-month observation period for detecting alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.

A 1.5-inch segment of about 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, providing an optimal sample for analysis and corroboration. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be lacking, an equivalent quantity of body hair may be used. In discussing head hair, we specifically mean scalp hair. Body hair refers to all other types, including facial and axillary hair.

Process Overview

The key steps in laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of encoding a sample in a laboratory’s system. This entails ensuring the sample was properly sealed and shipped, assigning it a LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent in an electronic chain of custody system.

Screening comprises an initial rapid assessment for drugs. Although screening is cost-efficient for eliminating drug usage in most samples, a positive screen must be validated to stand in court. Samples showing presumptive positivity in Screening demand a follow-up confirmation.

Should a sample be presumptively positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. In this stage, drugs are distilled from hair at a far lower concentration than other techniques (e.g., urine or saliva), explaining the complexity of hair drug screening.

Confirmation of positive screening outcomes is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation follows scrutiny under both the CAP (College of American Pathologists) Hair protocol and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests reveal drug use for up to 90 days, unlike urine tests with shorter detection durations.
• Difficult to manipulate: Cheating a hair drug test is quite challenging, ensuring more reliable results.
• Conveys usage history: It provides an overview of drug use over time, not just recent intake.

Limitations:

• Lacks recent use detection: Drugs typically take 5-7 days to manifest in hair.
• Expense: Hair tests often cost more than alternative drug testing methods.
• Result variations: Elements like hair color and growth rate can impact the level of drug metabolites in hair.

Note: Though they are frequently called "hair follicle tests", the analysis targets the hair strand not the hair follicle beneath the scalp.
