Hair Follicle Drug Testing - Dallas, WI

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair retains a detailed record of alcohol and drug intake by embedding biomarkers in the strands as they grow. When sampled near the scalp, hair can offer a detection window of up to three months for alcohol and drugs. It's easy to collect, relatively tamper-proof, and convenient to transport.

A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil) close to the scalp will yield 100mg of hair, which is optimal for screening and confirmation processes. For EtG assessments and tests exceeding 10 panels, a recommendation of 150mg is given. It's advisable to weigh the sample with a jeweler's scale. If scalp hair isn't available, an equivalent quantity of body hair may be collected. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all other hair types (such as facial and axillary hair).

Process Overview

The laboratory analysis of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a lab's system. This step verifies that the sample is properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and addresses any additional data input not covered by an electronic chain of custody.

Screening is a preliminary and economical procedure to identify the presence of drugs. Although useful for excluding drug use in most samples, a positive screening result necessitates further confirmation for legal admissibility. Any samples yielding presumptive positive results during Screening must undergo secondary confirmation.

Upon a presumptive positive outcome at the Screening phase, additional hair is extracted from the original specimen for Extraction. This procedure involves isolating drugs from hair at a notably lower concentration than other methods such as urine or oral fluid tests, making hair drug testing a challenging process.

Confirmation of any positive screening result uses techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are subjected to cleansing before the confirmation stage as needed. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests indicate drug use up to 90 days, surpassing the shorter window of urine tests.
• Resistance to tampering: Cheating hair drug tests is notably challenging, enhancing result reliability.
• Historical insight: It reveals long-term drug usage trends, not limited to recent consumption.

Limitations:

• Inability to identify recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests usually incur higher costs than other testing techniques.
• Result variability: Hair color and growth differences among individuals can influence drug metabolite concentration.

Note: Despite being termed "hair follicle tests", the analysis targets the hair strand, omitting the follicle beneath the scalp.
