Hair Follicle Drug Testing - Megler, WA

What it is, How it works

Recognized as a formidable technique for tracing drug and alcohol consumption, hair testing offers a comprehensive overview by embedding biological markers in the strands of developing hair. When collected near the scalp, this type of sample can provide up to a three-month window for detecting alcohol and drugs. It is straightforward to gather, relatively challenging to tamper with, and convenient for shipping.

To achieve optimal results for screening and confirmation, a 1.5-inch sample comprising roughly 200 hair strands (similar in diameter to a #2 pencil) nearest the scalp, yielding 100mg, is considered ideal. For EtG analyses, add-ons, and/or more than 10-panel tests, 150mg is preferred. It is advisable to measure the sample using a jeweler's scale. In cases where scalp hair is absent, a comparable quantity of body hair can be collected. When referring to head hair, only scalp hair is considered. All other hair types, such as facial and axillary, fall under body hair.

Process Overview

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

Accessioning entails integrating a sample into a lab's system initially. This step ensures the sample was properly sealed and transported, assigns it a LAN (Laboratory Accessioning Number) randomly, and completes any additional required data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid assessment for illicit substances. Though it serves as a cost-effective method to eliminate drug use in most samples, a positive result in Screening must be confirmed for court admissibility. Samples that show presumptive positivity in Screening need further confirmation.

Should a sample present as presumptively positive during Screening, additional hair is extracted from the initial sample to prepare for Extraction. Here, drugs are isolated from hair at much reduced concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples identified as presumptive positives are cleansed prior to confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, surpassing the shorter window of urine tests.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Historical insight: It portrays a pattern of drug usage over time, unlike just recent consumption.

Limitations:

• Incapable of spotting recent usage: Drugs typically take 5-7 days to be noticeable in hair.
• Expense: Hair drug tests generally incur higher costs than other methods.
• Result variability: Elements like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests," the actual analysis involves examining the hair strand rather than the follicle beneath the scalp
