Hair Follicle Drug Testing - Sidon, AR

What it is, How it works

Hair examinations are recognized as an effective method for identifying drug and alcohol usage. Hair offers an extended timeline of substance use by embedding biomarkers within the strands as they develop. When sourced near the scalp, hair can yield an approximate detection span of 90 days for drugs and alcohol. Collecting hair is straightforward, somewhat resistant to tampering, and straightforward to transport.

A sample length of 1.5 inches comprising around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for analysis. For EtG extensions and/or tests exceeding ten panels, it is advisable to use 150mg. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair is not available, an equal volume of body hair can be gathered. "Head hair" refers exclusively to scalp hair, whereas "body hair" refers to all other hair types (such as facial or axillary).

Process Overview

The laboratory handling of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial processing of a specimen into the lab system. This step ensures that the sample is properly sealed and transported, allocates a random Laboratory Accessioning Number (LAN), and completes any other necessary data entries not covered by an electronic custody system.

Screening provides an initial, rapid evaluation for drug presence. While this stage is cost-effective to exclude drug use for most samples, a positive result requires validation for legal admissibility. Any samples indicating a presumptive positive in Screening necessitate further confirmation.

For samples showing presumptive positivity in the Screening phase, additional hair is taken from the original specimen and prepped for Extraction, a stage where drugs are withdrawn from hair at a significantly lower concentration compared to other methods (like urine or oral fluid), which makes hair drug screening the most challenging to execute.

Confirming any positive screen results employs methods such as GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positive outcomes are washed before confirmation if needed. The complete lab procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug analyses can uncover drug use up to 90 days, in contrast to urine tests which offer a briefer detection period.
• Cheating difficulty: Manipulating a hair drug test is quite difficult, leading to more reliable results.
• Historical insight: It reveals a timeline of drug use, not merely recent activity.

Limitations:

• Lacks recent usage detection: Drugs typically become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally cost more than alternate drug testing methods.
• Result variability: Factors like hair color or individual variations in hair growth can influence drug metabolite concentrations within the hair.

Note: Although often termed "hair follicle tests", the analysis actually considers the hair strand, not the follicle beneath the scalp.
