Hair Follicle Drug Testing - White Marsh, MD

What it is, How it works

Utilizing hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair acts as a repository of a long-term usage record by embedding biomarkers within the strands as they grow. If collected near the scalp, hair provides a look-back period of roughly 3 months for tracing alcohol and drug usage. The process of obtaining hair samples is straightforward, it's relatively resistant to tampering, and it can be transported with ease.

A sample that is 1.5 inches in length and consists of nearly 200 strands (about the thickness of a #2 pencil) taken closest to the scalp will yield 100mg of hair, which is the optimal quantity for initial testing and confirmation. For EtG, add-ons, or testing above 10 panel levels, a 150mg sample is suggested. We advocate for utilizing a jeweler’s scale to weigh the sample. Should scalp hair not be available, an equivalent measure of body hair is viable for collection. Our mention of head hair is specifically regarding scalp hair, whereas body hair includes other types of hair (such as facial and axillary hair).

Simplified Process Description

The four principal stages in the lab processing of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial registration of a sample into a lab’s framework. This step involves confirming the sample’s proper sealing and shipment, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody method.

Screening denotes an initial broad scan for drug presence. While it's an economical approach to dismiss drug usage in most samples, a positive outcome from this check needs subsequent confirmation for legal acceptability. Samples flagged as presumptively positive during Screening require further confirmation.

Upon presuming positivity at the Screening phase, additional hair is drawn from the initial sample and readied for Extraction. During Extraction, drug components are retrieved from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), which explains why hair drug testing is considered one of the more complex methods.

Confirmation for any positive found during screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples marked as presumptively positive undergo a cleansing step before confirmation when necessary. The laboratory sequence from Accessioning to Confirmation is conducted under the guidelines of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Hair drug testing strengths include:

• Extended detection period: Hair drug tests can identify drug consumption for as long as 90 days, far exceeding the shorter timing of urine tests.
• Hard to circumvent: Cheating a hair drug test poses significant difficulty, thereby ensuring more reliable results.
• Conveys historical usage: It reveals a pattern of substance use over a span of time, not restricted to recent activities.

Drawbacks:

• Incapable of detecting recent ingestion: There's approximately a 5-7 day delay before drugs become traceable in hair.
• Expense: Hair drug tests usually incur higher costs compared to other drug testing techniques.
• Result inconsistency: Hair color and individual disparities in hair growth can influence the level of drug metabolites present in the hair.

Note: Although commonly called "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing excels over urine tests in White Marsh, MD due to its enhanced detection capability and reliability. While urine tests scan for recent drug use, hair tests provide a clearer picture of substance consumption over a prolonged period. Employers gain a more comprehensive understanding of an individual's drug history, thus supporting more informed decision-making.

Another significant advantage of hair follicle testing is its resistance to tampering. While urine samples can be adulterated or substituted, hair samples are collected with greater integrity, ensuring results that are much harder to manipulate. This makes hair testing a more trustworthy method for employers and legal entities enforcing drug policies.

Extended Detection Window

Hair follicle testing in White Marsh, MD offers an expansive detection window, capturing drug usage for up to 90 days. This capability gives employers a thorough insight into a person's substance history, crucial for roles demanding trust and reliability. Unlike other tests, hair samples reveal patterns of behavior, not just isolated incidents.
With such an elongated detection period, employers can better evaluate consistency in an individual's substance use, aiding in the assessment of long-term trends over time.

Tamper-Resistant Testing Method

In White Marsh, MD, the integrity of hair follicle testing lies in its resistance to tampering. Unlike urine tests, which are vulnerable to adulteration, hair samples are collected under strict conditions that curtail the chances of illicit manipulation. This reliability ensures results maintain their legitimacy.
