Hair Follicle Drug Testing - Flores, AZ

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-standing record of alcohol and drug presence by embedding biomarkers within the fibers of a growing hair strand. Collected near the scalp, hair can reveal a timeframe of up to roughly 90 days for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 strands of hair (comparable to the size of a #2 pencil) taken nearest to the scalp, yields 100mg of hair, the preferred amount for both screening and confirmatory purposes. For EtG, additional tests, or screenings beyond 10 panels, a sample size of 150mg is advisable. Utilizing a jeweler’s scale for accurate measurement is recommended. If scalp hair cannot be accessed, a similar quantity of body hair may be obtained. When we mention head hair, it specifically pertains to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug testing outcome is performed through four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a specimen into a lab’s framework. This step involves ensuring the sample was appropriately sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody mechanism.

Screening involves a preliminary assessment for substance misuse. Although Screening offers an economical approach to eliminating drug usage for the majority of specimens, a positive screening result necessitates confirmation for legal admissibility. Presumptive positive samples in Screening indeed require a follow-up confirmation.

Should a sample test positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. At this phase, drug substances are extracted from hair at notably low concentrations compared to other methods (like urine or oral fluid), underscoring why hair drug testing is the most complex methodology to conduct.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation as required. The overall lab procedure, from Accessioning to Confirmation, is thoroughly reviewed under CAP (College of American Pathologists) Hair designation, and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing identifies drug use up to 90 days, unlike urine tests that have a more limited timeframe.
• Resistant to tampering: Cheating a hair drug test is particularly challenging, increasing the reliability of results.
• Offers historical data: It charts drug use over a duration rather than only recent use.

Limitations:

• Cannot detect recent usage: Drug presence in hair becomes detectable only after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variability: Variables such as hair color and individual hair growth rates can influence drug metabolite concentration in the hair.

Note: Although often termed as "hair follicle tests," the analysis is performed on the hair strand, not on the follicle beneath the skin.
