Hair Follicle Drug Testing - Grimes, IA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline for alcohol and drug detection by capturing biomarkers in the strands of hair as it grows. When gathered near the scalp, hair can provide data on usage for nearly 3 months. It’s straightforward to collect, challenging to tamper with, and easy to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (approximately the diameter of a #2 pencil), nearest the scalp, provides 100mg of hair, perfect for screening and validation. For EtG, supplementary tests, or panels above 10, a 150mg sample is suggested. It’s advisable to measure the sample with a jeweler’s scale. If there is no scalp hair, a similar quantity of body hair can be utilized. When head hair is mentioned, it refers specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial incorporation of a specimen into the lab system. This step includes checking the sample’s seal and shipping integrity, assigning it a random LAN (Laboratory Accessioning Number), and completing further data input if not provided via an electronic chain of custody.

Screening offers a quick initial assessment for substances of abuse. Though cost-effective, a Screening’s positive result must be confirmed to be valid in a legal setting. Any samples with a positive result during Screening need additional confirmation.

If a sample shows a presumptive positive in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at lower concentrations compared to other tests (like urine or oral fluid), making hair drug testing the most complex methodology.

Verification of any positive screen results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as necessary. The entire process from Accessioning to Confirmation is audited under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests detect substance use up to 90 days, unlike urine tests with shorter periods.
• Hard to manipulate: Hair drug tests are difficult to falsify, providing more reliable results.
• Offers historical context: The tests show a pattern of drug usage over time, beyond just recent use.

Limitations:

• Incapable of detecting recent usage: A delay of about 5-7 days is needed for drugs to show up in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result discrepancies: Elements like hair color and individual hair growth variations can alter drug metabolite concentrations in hair.

Note: Referred to as "hair follicle tests", this test analyzes the hair strand rather than the follicle beneath the scalp.
