Hair Follicle Drug Testing - Landfall, MN

What it is, How it works

Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. It offers a detailed historical record of alcohol and drug intake by embedding biomarkers in the strands of growing hair. When gathered near the scalp, hair can offer a detection window of approximately three months for both alcohol and drugs. Collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch sample comprising roughly 200 hair strands (comparable to the size of a #2 pencil) taken nearest to the scalp provides 100mg of hair, which is the optimal amount for screening and verification. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory processing of a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory system, which includes verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and concluding any extra data entry missing from an electronic chain of custody system.

Screening offers an initial, rapid assessment for substances of abuse. Although Screening is a cost-effective method to exclude drug use in most samples, a positive Screening result must be confirmed to be admissible in judicial proceedings. Any samples deemed presumptively positive in Screening require subsequent confirmation.

When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample for further Extraction. This phase isolates drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most sophisticated methodology.

Confirmation of any positive Screening findings is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples are washed pre-confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited timeframe.
• Challenging to deceive: Hair drug tests are highly resistant to manipulation, enhancing result accuracy.
• Offers historical insights: It reveals trends in drug use over time, not only recent activity.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than other testing techniques.
• Result variability: Elements such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests", the procedure actually analyzes the hair strand, not the follicle beneath the scalp.
