Hair Follicle Drug Testing - Charles City, IA

What it is, How it works

Hair examinations have gained recognition as an effective means for identifying the consumption of drugs and alcohol. Hair offers a prolonged history of substance use by encapsulating biomarkers within the fibers of the maturing hair strand. When collected near the scalp, it can present an approximate 3-month detection period for drugs and alcohol. Hair is straightforward to collect, moderately challenging to tamper with, and easy to transport.

A 1.5-inch portion of approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp provides 100mg, the optimal amount for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. It's recommended to weigh the sample using a jeweler’s scale. If head hair is not available, an equivalent quantity of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the initial integration of a sample into a lab’s system. This step includes confirming the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody system.

Screening is an initial rapid assessment for substances of misuse. Though Screening is cost-efficient in eliminating drug use for most samples, a positive result requires confirmation to be admissible in legal contexts. Samples presumed positive in Screening demand secondary verification.

Should a sample show a presumptive positive at the Screening phase, additional hair is taken from the initial sample and prepped for Extraction. Here, the extraction of drugs from hair occurs at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a notably complex procedure.

Confirmed positive Screening outcomes undergo GC/MS, GC/MS/MS, or LC/MS/MS processes. Presumptive positive samples are washed before confirmation as necessary. The complete lab sequence from Accessioning to Confirmation is scrutinized under the guidelines of the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can uncover drug use for up to 90 days, unlike urine tests with a reduced detection timeframe.
• Resistance to tampering: Tampering with a hair drug test is exceedingly challenging, increasing result reliability.
• Offers historical insight: It can reveal a history of drug consumption, not merely recent occurrences.

Limitations:

• Inability to detect recent use: It requires roughly 5-7 days for substances to be identifiable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.
