Hair Follicle Drug Testing - Heflin, LA

What it is, How it works

Utilizing hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair preserves a prolonged record of substance use by embedding biomarkers within the hair strand fibers as they grow. When taken close to the scalp, hair offers a detectability period extending up to roughly three months for alcohol and drug presence. Hair collection is straightforward, comparatively hard to tamper with, and convenient to send.

A specimen of 1.5 inches, consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal quantity for evaluation and verification. For EtG, additional tests, and/or panels exceeding ten, a specimen amount of 150mg is advised. It's suggested to measure the sample weight utilizing a jeweler’s scale. Should scalp hair be absent, an equivalent volume of body hair is permissible for collection. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory procedures for processing drug tests encompass four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning relates to the preliminary integration of a sample into the laboratory system. Tasks include ensuring the sample is appropriately sealed and transported, assigning a randomized LAN (Laboratory Accessioning Number), and finalizing any supplemental data entry absent from an electronic custody tracking system.

Screening represents an initial rapid assessment for substance misuse. While Screening is a cost-effective approach to exclude drug usage in most samples, any positive detection requires verification for judicial validity. Samples that initially test positive during Screening mandate further Confirmation.

Should a sample indicate a presumptive positive in the Screening phase, additional hair is separated for the Extraction step. During Extraction, drugs are isolated from hair at considerably less concentration compared to other techniques (e.g., urine or oral fluid), underpinning the complexity of conducting hair drug screening.

Confirmation of positive Screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo washing prior to Confirmation as necessitated. The entire laboratory process, from Accessioning through Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair label and ISO/IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can recognize drug use up to 90 days, unlike urine tests, which have shorter detection windows.
• Challenging to circumvent: Cheating is notably difficult for hair drug tests, enhancing result accuracy.
• Historical usage insight: It can reveal a pattern of substance use over a duration rather than just recent intake.

Limitations:

• Inability to detect recent intake: A duration of about 5-7 days is necessary before drugs become traceable in hair.
• Expense: Hair drug tests often incur higher costs compared to other testing methods.
• Result variability: Factors such as hair color and individual hair growth variations may influence drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", only the hair strand is analyzed, excluding the hair follicle beneath the scalp.
