Hair Follicle Drug Testing - Corriganville, MD

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. It serves as a long-lasting record of alcohol and drug intake by capturing biomarkers within the strands of hair as they grow. When clipped close to the base, hair can offer an approximate 90-day detection range for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A hair sample of 1.5 inches consisting of roughly 200 strands (comparable to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advisable. It is suggested to use a jeweler’s scale for weighing. If scalp hair isn't available, a comparable amount of body hair can be taken. When we mention head hair, it pertains to scalp hair exclusively, whereas body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The primary phases in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab’s system. This process involves confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and entering any supplementary information absent in an electronic chain of custody system.

Screening entails an initial swift examination for substance abuse. Though Screening is a cost-efficient approach for excluding drug use in most specimens, a positive screen needs verification to hold up in legal settings. Any specimens showing presumptive positivity in Screening necessitate a follow-up confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the original sample and readied for Extraction. During this stage, drugs are isolated from hair at far lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate procedure to execute.

Verification of any positive Screening outcomes is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation if necessary. The comprehensive lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Prolonged detection span: Hair drug analyses can identify drug usage for as long as 90 days, unlike urine tests which have a shorter time frame.
• Hard to bypass: Cheating on a hair drug test is highly difficult, thereby enhancing the accuracy of results.
• Presents historical usage: It can reveal a pattern of substance use across a timeline, not solely recent consumption.

Drawbacks:

• Cannot identify recent consumption: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than alternative drug testing approaches.
• Result inconsistencies: Elements like hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: While commonly termed as "hair follicle tests", the examination involves the hair strand, not the follicle beneath the scalp.
