Hair Follicle Drug Testing - Humboldt, AZ

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of substance use by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair may offer around a 3-month window for detecting alcohol and drug use. Hair is easy to collect, somewhat hard to tamper with, and straightforward to transport.

A 1.5-inch portion of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp can provide 100mg, which is the optimal amount for both screening and confirmation purposes. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weighing the specimen is advised. In cases where scalp hair is not available, an equivalent amount of body hair may be utilized. When mentioning head hair, it exclusively means scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary phases in a laboratory's analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial handling of a sample into a lab’s system. This consists of ensuring the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and concluding any extra data entry absent in an electronic chain of custody system.

Screening constitutes a preliminary rapid analysis for substances of abuse. While Screening is an economical method to negate drug usage in most samples, a positive result needs further verification to be valid in legal proceedings. Samples presumed positive during Screening require additional confirmation.

If a sample is presumed positive during Screening, more hair is extracted from the original specimen and set for Extraction. In this phase, substances are extracted from hair at considerably lower concentrations than alternative methods (ex. urine or oral fluid), which makes hair drug screening a challenging process.

Confirmation of any positive screening finding is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumption of positive samples undergoes washing prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection timeframe.
• Hard to deceive: Hair drug evaluations are challenging to bypass, improving result precision.
• Offers historical insights: It can reveal a pattern of substance use over time, not merely recent intake.

Limitations:

• Inability to identify recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug evaluations tend to be costlier than other testing methods.
• Outcome fluctuations: Factors like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Frequently labeled as "hair follicle tests", the analysis evaluates the hair strand, not the follicle beneath the scalp
