Hair Follicle Drug Testing - Tolchester Beach, MD

What it is, How it works

Hair analysis has established itself as an effective mechanism for identifying drug and alcohol usage. The fibers of growing hair strands capture biomarkers, providing a lengthy record of substance exposure. When sampled near the scalp, hair can offer an approximate 3-month window of detection for both alcohol and drugs. Collection is straightforward, hard to tamper with, and shipping is uncomplicated.

A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for analysis and confirmation. For tests like EtG, add-ons, or panels exceeding 10, a 150mg sample is advised. It's best to weigh the sample using a jeweler’s scale. In absence of scalp hair, a similar quantity of body hair can be gathered. The term head hair strictly refers to scalp hair. Body hair encompasses facial, axillary, and other types of hair.

Process Overview

The laboratory procedure to process a drug test result involves these primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of the sample into the laboratory system. This step ensures the sample's seal and shipment were intact, assigns a random LAN (Laboratory Accessioning Number) and fills in any additional data not covered by an electronic chain of custody system.

The Screening phase provides an initial rapid evaluation for drugs of abuse. Though it's a cost-effective means to exclude drug use for most samples, a positive screen requires confirmation to be court-admissible. Samples testing presumptively positive during screening need further confirmation.

When a sample is presumptively positive at Screening, additional hair is taken from the primary sample for Extraction. In this phase, drugs are separated from hair at much lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug testing a challenging method to perform.

Confirmation of any positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation as necessary. From Accessioning through Confirmation, the whole laboratory procedure is vetted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug screening can trace drug usage up to 90 days, unlike urine tests that offer a shorter detection timeframe.
• High resistance to tampering: Cheating a hair drug test is exceedingly hard, ensuring precise results.
• Provides historical data: It offers a drug usage trend over time, rather than recent usage alone.

Limitations:

• Cannot detect recent usage: A time frame of about 5-7 days is required for drugs to be present in hair.
• Expense: Hair drug testing generally incurs higher costs compared to other testing methods.
• Result variations: Differences such as hair color and personal hair growth rates can influence the drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the examination focuses on the hair strand, excluding the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Tolchester Beach, MD, hair follicle testing outperforms traditional urine testing by offering a more extended detection period and heightened reliability. Unlike urine tests which detect recent use, hair tests provide insights into a longer history of substance use, bolstering employer confidence in the accuracy of test results.
