Hair Follicle Drug Testing - East Laurinburg, NC

What it is, How it works

Hair analysis has become recognized as an effective means for identifying drug and alcohol usage. Hair strands preserve a long-term record of alcohol and various drugs by capturing biomarkers within the fibers as hair grows. If collected near the scalp, hair analysis can offer roughly a 3-month detection period for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and convenient to send.

A 1.5-inch section consisting of about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal amount for initial testing and verification. For EtG, extra tests, and/or panels exceeding 10, 150mg of hair is advised. It's recommended to use a jeweler’s scale for weighing the sample. If scalp hair is not available, a similar quantity of body hair may be used. References to head hair specifically mean scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory drug test result processing involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the entry of a sample into the lab's system. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drug presence. Despite being a cost-effective approach to eliminate drug usage in most samples, a positive screening must be confirmed for court admissibility. Samples that are presumptively positive in Screening require additional confirmation.

Should a sample be presumptively positive during Screening, more hair is taken from the initial sample for Extraction. This stage involves extracting drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging method to perform.

Confirmation of a positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, undergoes assessment under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests offer detection of drug use for up to 90 days, unlike urine tests with a shorter window.
• Harder to falsify: Cheating a hair drug test is highly challenging, leading to more reliable results.
• Historical usage data: It presents a usage pattern over time, instead of only recent activities.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Cost implications: Generally, hair drug tests are pricier than other testing methods.
• Result variability: Variables like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", these tests analyze the hair strand rather than the hair follicle under the scalp.
