Hair Follicle Drug Testing - Meta, MO

What it is, How it works

Hair screening is increasingly recognized as an effective means for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of developing hair strands, hair offers a prolonged history of substance use. When collected near the scalp, it gives a detection period of up to roughly three months for alcohol and other substances. Collection is straightforward, alteration is challenging, and shipping is uncomplicated.

A sample measuring 1.5 inches, comprising around 200 hair strands (approximately the thickness of a standard pencil), situated nearest to the scalp provides 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG additional tests or panels exceeding 10, a 150mg sample is advised. We suggest assessing the specimen's weight using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Body hair includes all other types (such as facial and axillary).

Process Overview

The laboratory evaluates a drug test outcome through four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial incorporation of a sample into a lab's system. This step entails ensuring the sample's seal and shipment are correctly executed, labeling it with a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent in an electronic chain of custody system.

Screening entails a preliminary swift assessment for substances of abuse. Although Screening is a cost-efficient method to eliminate drug usage in the majority of samples, a positive screening must be confirmed for court admissibility. Samples showing presumptive positivity during Screening necessitate further confirmation.

If a sample is found presumptively positive during Screening, additional hair from the initial sample is extracted and readied for Extraction. In this phase, drugs are isolated from hair at concentrations significantly lower than with other methodologies (such as urine or oral fluids), underscoring why hair drug screening is the most intricate methodology to execute.

GC/MS, GC/MS/MS, or LC/MS/MS technologies conduct the Confirmation of any positive screening results. Prior to confirmation, any samples with presumptive positivity undergo a necessary wash. The comprehensive laboratory process, spanning from Accessioning to Confirmation, undergoes scrutiny per the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection time-frame: Hair drug tests can identify drug use over a 90-day period, in contrast to urine tests, which have a briefer detection span.
• Improbable to falsify: Cheating a hair drug test is extremely difficult, thus enhancing result accuracy.
• Offers historical insights: It displays a drug use pattern over time, not just recent activity.

Limitations:

• Inability to detect recent use: Drugs become identifiable in hair approximately 5-7 days after consumption.
• Expense: Hair drug tests tend to be pricier compared to other methods.
• Result variability: Influences such as hair color and individual differences in hair growth can impact drug metabolite concentration within hair.

Note: Although frequently termed as "hair follicle tests", the analysis is performed on the hair strand itself rather than the follicle beneath the scalp.
