Hair Follicle Drug Testing - Crookston, NE

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol usage. Hair offers an extended record of alcohol and drug consumption by capturing biomarkers within the fibers of the hair as it grows. When taken from close to the scalp, hair can provide a detection window of up to roughly 3 months for alcohol and other substances. Hair is straightforward to collect, challenging to manipulate, and easy to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp offers 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional testing, and/or tests exceeding 10 panels, 150mg of hair is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, a comparable quantity of body hair may be used. 'Head hair' refers specifically to scalp hair, while 'body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the initial step of introducing a sample into a laboratory's system, which entails confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.

Screening is an initial quick assessment for drugs of abuse. While Screening is a cost-effective method for ruling out drug usage in most samples, a positive result requires confirmation to be admissible in legal contexts. Any samples that return presumptively positive results in Screening necessitate a secondary confirmation.

If a sample tests presumptively positive during Screening, further hair is extracted from the initial sample and processed for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening is considered the most challenging methodology.

Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are deemed presumptively positive are washed before confirmation if necessary. The entire process, from Accessioning to Confirmation, is reviewed in accordance with the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days in contrast to urine tests, which have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is highly challenging, ensuring more accurate results.
• Shows historical usage: It can demonstrate a pattern of drug use over time, rather than just recent use.

Limitations:

• Incapable of identifying recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Higher cost: Hair drug tests tend to be more expensive than other drug testing options.
• Result variability: Factors like hair color and personal differences in hair growth may influence the concentration of drug metabolites in the hair.

Note: Though commonly referred to as "hair follicle tests," the assessment actually examines the hair strand, not the follicle beneath the scalp.
