Hair Follicle Drug Testing - Lambs Grove, IA

What it is, How it works

Considered nowadays as an effective method for identifying drug and alcohol consumption, hair testing offers a detailed timeline of substance use by capturing indicators within the strands of hair as they grow. When sampled near the scalp, hair can show evidence of substance usage for up to around three months. The collection process is straightforward, making tampering difficult, and enables easy transportation.

A 1.5-inch section consisting of approximately 200 strands (about the size of a #2 pencil) near the scalp weighs about 100mg, which is the optimal amount for both screening and confirmation. For tests involving EtG, additional screenings, or more than 10 panels, 150mg of hair is advised. It is recommended to use a jeweler’s scale to weigh the sample. If scalp hair is not accessible, a similar amount of body hair can be used. The term head hair references only scalp hair, while body hair includes all other hair types (such as facial, axillary, etc.).

Process Overview

The drug testing laboratory process is divided into four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is incorporated into the laboratory's system. This step ensures the sample was sealed and transported correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any missing data entry required by the electronic chain of custody system.

Screening conducts a preliminary inspection for drugs of abuse. This process is cost-efficient for eliminating drug presence in the majority of samples; however, for legal admissibility, a positive route via screening requires confirmation. Samples drawing a presumptive positive during Screening necessitate a validating confirmation stage.

Should the Screening identify a presumptive positive, additional hair is extracted from the original sample to prepare for Extraction. At this stage, the drugs are isolated from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid testing), highlighting the intricate nature of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS technology is employed for the Confirmation of any positive results from Screening. Prior to final verification, all samples with a presumptive positive status are washed accordingly. Overarching the entire procedure from Accessioning through to Confirmation, reviews are governed under both the CAP (College of American Pathologists) Hair certification and the accreditation adhering to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection scope: Unlike urine tests, hair drug evaluations are capable of identifying drug activity up to 90 days back.
• Resistant to tampering: The difficulty in falsifying hair drug test results ensures higher accuracy.
• Shows historical patterns: Offers insights into the frequency of drug use, beyond just recent consumption.

Limitations:

• Inability to report recent usage: Drugs require roughly 5-7 days to appear detectable in hair.
• Expensive: Typically, hair drug tests cost more than other prevalent testing modalities.
• Result variability: Variables such as hair pigmentation and individual hair growth factors can influence drug metabolite concentration in hair.

Note: The tests commonly called "hair follicle tests" in fact focus on analyzing the hair strand itself and not the follicle beneath the scalp.
