Hair Follicle Drug Testing - Crosby, MD

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a chronological record for alcohol and various substances by capturing biomarkers within the strands as they grow. When samples are taken near the scalp, they offer a detection span of up to three months for alcohol and other substances. Hair is easy to collect, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, composed of roughly 200 hair strands (similar in size to a #2 pencil) taken from the scalp equals 100mg of hair, which is the preferred sample size for both screening and confirmatory purposes. For comprehensive analyses like EtG, add-on tests, or those exceeding 10 panels, 150mg of the sample is advisable. It is suggested to use a jeweler's scale to measure the sample's weight. If scalp hair isn't accessible, equivalent amounts of body hair may be gathered. The term "head hair" refers specifically to hair on the scalp, whereas "body hair" includes all other types (like facial or axillary hair).

Process Overview

The laboratory process in determining a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial process of introducing a sample into the laboratory's system. It entails checking that the sample has been correctly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and performing any extra data entry not included by an electronic chain of custody system.

Screening involves a preliminary rapid evaluation for illicit substances. Though Screening serves as a cost-efficient method to negate drug usage in most samples, any positive result from screening must be verified for legal admissibility. Thus, samples testing presumptively positive during Screening necessitate further confirmation.

For samples that turn positive in the Screening phase, more hair is extracted from the original sample and prepped for Extraction. During this stage, substances are extracted from hair at significantly lower concentrations than other methods like urine or oral fluid tests, making hair drug analysis the most complex technique.

Confirmation of any tentative positive outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage for up to 90 days, unlike urine tests that offer a shorter detection window.
• Challenging to falsify: Hair drug tests are difficult to circumvent, thus ensuring more reliable results.
• Offers historical insight: It reveals a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Unable to detect recent use: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug tests are often pricier compared to other drug testing approaches.
• Result variations: Elements such as hair color and individual hair growth differences might influence drug metabolite concentration in hair.

Note: The procedure often referred to as "hair follicle tests" actually examines the hair strand and not the underlying hair follicle.
