Hair Follicle Drug Testing - North Chelmsford, MA

What it is, How it works

The use of hair analysis is recognized as a potent method for identifying drug and alcohol consumption. Hair retains a lasting record of substances by capturing biomarkers within its growing strands. By obtaining hair close to the scalp, it can provide a detection window of up to roughly three months for alcohol and other drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to ship.

A 1.5-inch hair sample comprising approximately 200 strands (equivalent to the diameter of a #2 pencil) closest to the scalp weighs around 100mg, which is the optimal sample size for both screening and confirmation tests. For EtG, supplemental tests, or panels exceeding 10, a 150mg sample is advisable. It is suggested to measure the specimen using a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, we only refer to scalp hair. Body hair denotes all other hair types (such as facial and axillary).

Process Overview

The laboratory procedure for processing a drug test consists of four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into the lab's system. This step includes ensuring the sample's seal and shipment are intact, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry that isn't provided by an electronic chain of custody system.

Screening serves as an initial check for potential drug use. While it's an economical way to eliminate drug consumption for most samples, a positive screening result requires confirmation to be valid in legal proceedings. All samples that yield a presumptive positive in Screening require additional confirmation.

When a sample shows a presumptive positive during Screening, more hair is taken from the original sample for Extraction. In this step, drugs are extracted from the hair at much lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most challenging method to execute.

Confirmation of any positive result in screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are presumptive positive are cleansed as needed before confirmation. The entire lab process, from Accessioning to Confirmation, is comprehensively evaluated according to the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug use over a 90-day span, as opposed to urine tests with shorter spans.
• Hard to falsify: Cheating a hair drug test is highly difficult, enhancing result accuracy.
• Supplies historical data: It demonstrates a timeline of substance use over time, not just recent activity.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately within 5-7 days.
• Expense: Hair drug tests are usually costlier than other testing methods.
• Result variability: Hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests," the actual test evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In North Chelmsford, MA, hair follicle testing offers distinct advantages over traditional urine testing methods. Unlike urine tests, hair samples provide a more extended detection period, ensuring comprehensive insight into an individual's drug history.
