Hair Follicle Drug Testing - Clayton, IL

What it is, How it works

Hair analysis emerges as an effective methodology for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair offers an approximate 3-month detection timeline for alcohol and various drugs. Collecting hair is straightforward, somewhat resistant to tampering, and effortless to transport.

A 1.5-inch sample consisting of roughly 200 hair strands (around the size of a #2 pencil) nearest the scalp yields about 100mg, which is the optimal sample amount for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a quantity of 150mg of the specimen is advisable. We suggest verifying the specimen's weight using a jeweler's scale. In instances where scalp hair cannot be obtained, an equivalent amount of body hair may be gathered. The term "head hair" pertains strictly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the sample's initial integration into the laboratory's system, ensuring the sample was properly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening involves a preliminary evaluation for drug use. While a cost-effective method to eliminate drug use in most samples, a positive screening necessitates confirmation for courtroom admissibility. Samples that yield a presumptive positive result in Screening require secondary confirmation.

If a sample indicates a presumptive positive during the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are extracted at a significantly lower concentration than found in other methodologies (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Positive screening confirmations are performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a presumptive positive are washed pre-confirmation as required. From Accessioning to Confirmation, the entire laboratory process is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can detect drug usage spans up to 90 days, whereas urine tests have a more limited detection period.
• Resistance to tampering: The difficulty to manipulate a hair drug test yields more precise results.
• Historically informative: It can reveal a pattern of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent use: The detectable presence of drugs in hair requires an approximate 5-7 day lapse.
• Expense: Hair drug evaluations generally incur greater costs compared to alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth variations can influence drug metabolite concentration in the hair.

Note: Commonly termed as "hair follicle tests", they examine the hair strand rather than the follicle beneath the scalp.
