Hair Follicle Drug Testing - Willow, MI

What it is, How it works

Hair testing is recognized as an effective method for assessing drug and alcohol consumption. Hair captures a long-term record of alcohol and drug presence by preserving biomarkers within the strands as they grow. When collected near the scalp, hair can reveal a detection period of up to three months for both alcohol and drugs. Collecting hair is straightforward, relatively challenging to tamper with, and simple to transport.

A 1.5-inch sample containing approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp will yield 100mg, which is the optimal sample size for screening and confirmation. For EtG, additional tests, and/or panels beyond 10, it is advisable to obtain 150mg of the specimen. It's suggested to measure the specimen using a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair may be collected. 'Head hair' denotes only scalp hair, while 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

There are four primary stages in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary processing of a sample into a laboratory's system. This process verifies the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic chain of custody system.

Screening provides an initial assessment for drug use. Although Screening is a cost-efficient method for ruling out drug use in most samples, a positive screening result requires confirmation to be legally valid. Presumptive positive samples detected during Screening must go through secondary confirmation.

Should a sample show presumptive positivity in the Screening phase, additional hair is taken from the initial sample for Extraction. During this stage, drugs are extracted from the hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging methodology to execute.

Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation, as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a shorter detection window.
• Challenging to deceive: It's exceedingly difficult to falsify results in a hair drug test, enhancing accuracy.
• Offers historical insight: It can chart drug use patterns over time, rather than just recent use.

Limitations:

• Incapable of detecting recent use: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variations: Variables such as hair color and individual hair growth differences can affect the drug metabolite concentration in hair.

Note: Despite being commonly referred to as "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp.
