Hair Follicle Drug Testing - Engelhard, NC

What it is, How it works

Hair analysis is recognized as a potent approach for identifying drug and alcohol consumption. The hair provides an extended timeline of alcohol and drug usage, capturing biomarkers within the strands as the hair grows. When cut close to the scalp, hair offers approximately a 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and simple to transport.

A 1.5-inch portion of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal amount for both testing and confirmation. For EtG, optional tests, or screenings beyond 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. When mentioning head hair, it refers strictly to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The processing of drug test outcomes in a laboratory follows four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a specimen into the laboratory system. This step includes confirming that the sample is properly sealed and transported, generating a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening refers to a swift initial scan for drug presence. While Screening is an economical method to dismiss drug usage in most samples, any positive findings necessitate further confirmation to be legally supportive. Any samples flagged as potentially positive during Screening mandate a secondary verification.

Should a sample show potential positivity in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are isolated from hair at much lower concentrations than other methods (such as urine or oral fluid), marking hair drug screening as particularly challenging.

GC/MS, GC/MS/MS, or LC/MS/MS are employed for confirming any positive screening results. Prior to confirmation, all samples with presumptive positives undergo a washing procedure. The full laboratory process from Accessioning to Confirmation is reviewed as per both the CAP (College of American Pathologists) Hair specification and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug consumption for up to 90 days, whereas urine tests have a shorter detection range.
• High resistance to fraud: Cheating a hair drug test is extremely challenging, leading to more precise results.
• Shows usage history: It furnishes a timeline of drug use over several months, rather than merely recent usage.

Limitations:

• Cannot pinpoint recent usage: It requires about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests often incur higher costs compared to other drug testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth can impact the drug metabolite concentrations in hair.

Note: Though termed "hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the scalp
