Hair Follicle Drug Testing - Denton, MD

What it is, How it works

Hair examinations are acknowledged as an effective means for identifying substance and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the fibers of the hair shaft. When acquired near the scalp, hair can offer a detection span of up to three months for alcohol and drugs. Hair is effortless to gather, relatively tough to tamper with, and straightforward to transport.

A 1.5-inch segment consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for screening and verification. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of specimen is advisable. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is not available, the same amount of body hair can be collected. When addressing head hair, we mean scalp hair exclusively. Body hair covers all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample into a lab’s system. This encompasses confirming that the sample was correctly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not covered by an electronic chain of custody system.

Screening constitutes a preliminary swift assessment for substances of abuse. Screening is an economical method to discount drug usage in most samples; however, a positive screen requires validation to be acceptable in court. Samples that exhibit presumptive positivity in Screening do need secondary confirmation.

Should a sample indicate presumptive positivity during Screening, extra hair is withdrawn from the initial specimen for preparation in Extraction. In this stage, drugs are extracted from the hair at a lower concentration than through alternative techniques (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging methodology to execute.

Verification of any positive result from Screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The whole laboratory sequence from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug examinations can identify drug usage up to 90 days, in contrast to urine tests with a brief detection span.
• Challenge to deceive: It is extraordinarily challenging to deceive a hair drug examination, enhancing result accuracy.
• Delivers historical insight: It can reveal a drug use pattern over an interval of time, rather than just recent usage.

Limitations:

• Inability to detect recent usage: Drugs take roughly 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing techniques.
• Result discrepancies: Factors such as hair color and individual hair growth variations can influence the level of drug metabolites in the hair.

Note: Commonly referred to as "hair follicle tests", the analysis pertains to the hair shaft and not the follicle under the scalp.
