Hair Follicle Drug Testing - Dennis, OK

What it is, How it works

Hair analysis has emerged as an effective means for identifying substance use, including drugs and alcohol. Hair strands capture biomarkers in their fibers, offering a lengthy historical record of drug and alcohol consumption. When collected from the scalp, hair can provide detection for roughly a three-month period for both drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and easy to mail.

Taking a 1.5-inch segment consisting of about 200 hairs (approximately matching the girth of a #2 pencil) from the scalp will provide 100mg, the perfect sample size for both screening and confirmation tests. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is ideal. We advise using a jeweler's scale to weigh the sample. If scalp hair is unavailable, an equal quantity of body hair should be used. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, samples are initially logged into the lab's system. This step verifies the sample’s sealing and shipment, assigns a LAN (Laboratory Accessioning Number), and completes any necessary additional data entry absent from an electronic chain of custody.

Screening involves a preliminary check for drugs of abuse. Although Screening is efficient for ruling out drug use in most cases, a court-admissible positive requires confirmation. Any samples presumed positive in Screening necessitate confirmation.

Should a sample be presumptively positive in Screening, additional hair is extracted from the specimen for Extraction. Here, drugs are extracted at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging.

A confirmed positive result is secured using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples are cleansed as needed. The entire process, from Accessioning to Confirmation, falls under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use up to 90 days, unlike urine tests, which have abbreviated windows.
• Difficult to tamper with: The integrity of hair drug tests is difficult to compromise, enhancing accuracy.
• Historical data supply: They chart drug use patterns over time, not just recent occurrences.

Limitations:

• Inability to detect recent use: It typically takes 5-7 days for drugs to be identifiable in hair.
• Cost: Compared to alternative drug tests, hair testing is often pricier.
• Result variations: Individual differences, including hair color and growth rate, can influence drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests," these tests assess the hair strand itself, not the follicle beneath the scalp.
