Hair Follicle Drug Testing - Leigh, NE

What it is, How it works

Hair sample testing is recognized as an effective method for identifying drug and alcohol use. The hair captures a timeline of drug and alcohol presence, trapping biomarkers within the strands as they grow. When samples are taken near the scalp, it can offer up to a three-month window for detecting drugs or alcohol consumption. Hair collection is straightforward, hard to tamper with, and convenient for shipping.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp, provides about 100mg of hair, perfect for initial and confirmatory testing. For EtG and tests extending beyond ten panels, a 150mg sample is suggested. We advise using a jeweler’s scale for weighing the sample. Should scalp hair be lacking, an equivalent quantity of body hair can be collected. Head hair pertains to scalp hair exclusively, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The primary steps in the laboratory analysis of a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial phase where a sample is logged into a laboratory's system. This step includes ensuring the sample was properly sealed and transported, assigning a randomly generated LAN (Laboratory Accessioning Number), and completing any supplementary data entry if an electronic chain of custody system did not provide it.

Screening is a preliminary check for drugs of abuse. While it offers a cost-effective means to rule out drug use for most samples, any positive screening result requires confirmation to hold up in legal scenarios. Presumptively positive samples in Screening need further confirmation.

If a sample tests positive during Screening, additional hair is taken from the original sample for Extraction. This stage extracts drugs from hair in much smaller concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is notably challenging to execute.

Confirmation of a positive screen is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The complete lab process from Accessioning through to Confirmation is assessed under the CAP (College of American Pathologists) Hair guidelines and accredited to the ISO / IEC 17025 framework.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a limited detection timeframe.
• Cheat resistance: A hair drug test is tough to falsify, ensuring more reliable results.
• Historical insight: Provides a drug usage timeline over extended periods, not just recent use.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are typically more costly than other testing techniques.
• Result variability: Elements such as hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", the process analyzes the hair strand, excluding the hair follicle beneath the scalp.
