Hair Follicle Drug Testing - Chapman, AL

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a timeline of alcohol and drug usage by embedding biomarkers within the strands as they grow. Sampling hair near the scalp yields an approximate 3-month detection period for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch sample consisting of about 200 hair strands (roughly the width of a #2 pencil) near the scalp results in 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional tests, or panels exceeding 10 tests, 150mg of hair is advisable. It’s best to weigh the hair sample using a jeweler’s scale. When scalp hair is not accessible, a similar amount of body hair is acceptable. "Head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary hair).

Process Overview

The core steps in the lab processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab’s workflow. This process checks that the sample is sealed and shipped correctly, assigns an arbitrary LAN (Laboratory Accessioning Number), and fills in any missing data not covered by the electronic chain of custody protocol.

Screening provides a preliminary rapid assessment for drug presence. Although this step is economical for dismissing drug use in the majority of cases, any positive reading requires confirmation to be legally valid. Samples testing presumptively positive during Screening necessitate a follow-up confirmation.

For samples testing presumptively positive in Screening, additional hair is taken from the original sample for the Extraction process. During Extraction, drugs are isolated from hair at much lower concentrations than alternative methods (such as urine or oral fluid), highlighting why hair drug screening is the most intricate method to administer.

GC/MS, GC/MS/MS, or LC/MS/MS methods conduct the Confirmation of any positive screening outcome. All samples indicating presumptive positivity undergo washing before confirmation as needed. The processing journey from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair criteria and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection scope: Hair drug analysis can reveal drug use extending up to 90 days, unlike urine tests with shorter detection periods.
• Resistance to tampering: Hair drug tests are notably hard to falsify, enhancing result accuracy.
• Historical insight: They provide a trace of drug usage over time, not solely reflecting recent consumption.

Limitations:

• Inability to detect recent consumption: A period of approximately 5-7 days is required before drugs manifest in hair.
• Expense: Typically, hair drug testing incurs higher costs than alternative methods.
• Result fluctuations: Factors such as hair color and personal hair growth differences can alter drug metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests," the actual analysis examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Chapman, AL, hair follicle testing surpasses urine testing, offering enhanced advantages. The principal merit of hair testing is its superior detection window and reliability.
