Hair Follicle Drug Testing - Lenoir City, TN

What it is, How it works

Seen as a robust method for identifying drug and alcohol usage, hair testing has gained recognition. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers in the strands as they grow. When collected near to the scalp, hair may provide up to roughly a three-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and is easy to transport.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately the size of a #2 pencil) taken closest to the scalp provides 100mg of hair, which is the optimal sample for assessment and validation. For EtG, supplementary tests, or tests exceeding 10 panels, a 150mg specimen is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other varieties of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning means initially processing a sample into a laboratory's system. This process entails verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finishing any additional data entry not covered by an electronic chain of custody method.

Screening provides a preliminary swift check for drug abuse. While Screening offers a budget-friendly method to exclude drug usage in the majority of samples, a positive screen must be validated for court acceptance. Samples preliminarily positive in Screening require further verification.

If a sample shows potential positivity in the Screening phase, more hair is extracted from the initial specimen and is made ready for Extraction. During this phase, drugs are extracted from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), indicating why hair drug screening is notably challenging to execute.

Confirmation of any positive screener results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as potentially positive are cleansed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug usage up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Cheating resistance: It is nearly impossible to manipulate a hair drug test, enhancing result accuracy.
• Historical insight: It reveals a drug use pattern over time rather than just recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Generally, hair drug testing is more costly than other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth variations can influence the concentration of drug metabolites found in hair.

Note: Commonly referred to as "hair follicle tests", the test examines the hair strand rather than the hair follicle beneath the scalp.
