Hair Follicle Drug Testing - Coteau Holmes, LA

What it is, How it works

Hair tests have gained recognition as an effective means for identifying drug and alcohol consumption. By capturing biomarkers in the strands of growing hair, this method offers a prolonged record of alcohol and drug use. A sample taken near the scalp can reveal drug use over a period of up to three months. Collecting hair is straightforward, altering it is quite challenging, and shipping is convenient.

A hair sample of 1.5 inches consisting of roughly 200 strands (approximately the size of a #2 pencil) taken from near the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's recommended to use a jeweler's scale for weighing the sample. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. The reference to head hair specifically means scalp hair. In contrast, body hair encompasses all other types of hair (facial, axillary, etc.).

Overview of the Process

The drug test result lab processing comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial processing of a specimen within the lab's system. This step includes verifying that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry that might not be covered by an electronic chain of custody system.

Screening involves a quick preliminary check for substances of abuse. While Screening is a cost-efficient method to exclude drug usage in most samples, a positive screen requires confirmation to be legally admissible. Any samples that are preliminarily positive during Screening need a secondary confirmation.

Should a sample test positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction processing. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), which makes hair drug screening the most arduous methodology to implement.

GC/MS, GC/MS/MS, or LC/MS/MS techniques conduct the confirmation of any positive screening result. Prior to confirmation, all presumptive positive samples are washed as necessary. The comprehensive lab process from Accessioning through Confirmation is carried out under the oversight of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use up to 90 days back, in contrast to urine tests that offer a shorter detection window.
• Challenging to manipulate: It is notably tough to falsify a hair drug test, thus yielding more precise results.
• Offers historical insight: It shows a pattern of drug consumption over time, rather than solely recent use.

Limitations:

• Inability to detect very recent use: It requires about 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing techniques.
• Result variability: Aspects like hair color and individual differences in hair growth may influence drug metabolite concentrations in hair.

Important: Though often termed as "hair follicle tests," the examination actually involves the hair strand, not the hair follicle beneath the scalp.
