Hair Follicle Drug Testing - Brentwood, MD

What it is, How it works

Hair assessments have become a significant method for identifying drug and alcohol consumption. The hair captures enduring markers of alcohol and medications by encasing them in the strands of the progressing hair fiber. When taken near the scalp, hair reveals nearly a 3-month window for detecting alcohol and other drugs. Collecting hair is easy, somewhat resistant to tampering, and simple to send.

An optimal sample consists of a 1.5-inch cut of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp, providing 100mg of hair, suitable for analysis and validation. For EtG, supplementary tests, and/or assessments exceeding 10 panels, 150mg of hair is advisable. Utilizing a jeweler’s scale is suggested for measuring the sample. If scalp hair is missing, an equivalent quantity of body hair could be gathered. References to head hair imply scalp hair alone. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary phase of entering a sample into a lab’s records. This step ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any extra data input not managed by an electronic custody chain.

Screening offers an initial rapid assessment for drug usage. Although Screening effectively eliminates drug presence in most samples at a reduced cost, a positive screen requires validation for court acceptance. Any samples yielding a presumptive positive in Screening necessitate a secondary confirmation.

Should a Screening stage yield a presumptive positive, more hair from the original sample is extracted and readied for Extraction. Drugs are withdrawn from hair at much diminished concentrations than in other techniques (ex. urine or saliva), explaining why hair drug analysis is the most complex technique.

Confirmation for any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as necessary before confirmation. The comprehensive lab process, from Accessioning to Confirmation, undergoes review per both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug assessments can reveal drug use spanning up to 90 days, in contrast to urine tests with shorter detection periods.
• Reduced likelihood of evasion: Evading a hair drug test is quite challenging, enhancing result reliability.
• Offers historical insights: It can show a trend of drug consumption over time, not merely recent usage.

Limitations:

• Incapacity to identify recent use: It requires about 5-7 days for drugs to become visible in hair.
• Expense: Hair drug analyses generally incur higher costs than other drug testing strategies.
• Result variability: Variables such as hair pigmentation and individual hair growth differences can influence the drug metabolite concentration in the hair.

Note: Commonly known as "hair follicle examinations", the analysis targets the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Brentwood, MD, hair follicle testing is favored for its superior accuracy over conventional urine tests.
