Hair Follicle Drug Testing - El Dorado Springs, MO

What it is, How it works

Hair assessments have gained recognition as a robust means for identifying the consumption of drugs and alcohol. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the strands of growing hair. When samples are gathered near the scalp, the hair offers a detection period extending up to roughly 3 months for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.

A 1.5-inch portion containing around 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimum amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the specimen. If head hair is not available, a similar amount of body hair can be used. "Head hair" refers strictly to scalp hair. "Body hair" encompasses other hair forms (facial, axillary, etc.).

Process Overview

The key steps in a laboratory's processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample into the laboratory’s system. This step includes checking that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any required data input not accounted for by an electronic chain of custody system.

Screening consists of a swift preliminary examination for drugs of abuse. While Screening is cost-efficient for excluding drug usage in most samples, a confirmed positive test is needed for legal admissibility. Any samples showing preliminary positive results in Screening need additional verification.

If a preliminary positive result appears in Screening, more hair is sourced from the initial sample for Extraction. During this phase, drugs are removed from hair at a much lower concentration than other methods (like urine or oral fluid), which is why hair drug testing is one of the most arduous methodologies to conduct.

Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo necessary washing. The full laboratory procedure from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair criteria and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug usage for up to 90 days, opposed to urine tests which detect over a shorter span.
• Hard to manipulate: Cheating on a hair drug test is notably challenging, leading to more precise results.
• Offers usage patterns: It reveals a timeline of drug use spanning a considerable period, not just recent intake.

Limitations:

• No recent usage detection: It requires around 5-7 days before drugs can become detectable in hair.
• Expense: Hair drug assessments are typically pricier compared to other drug testing methods.
• Outcome variations: Elements like hair color and individual hair growth differences can impact the concentration of drug traces in the hair.

Note: While often termed as "hair follicle tests", the analysis is conducted on the hair strand and not the follicle beneath the scalp.
