Hair Follicle Drug Testing - Kings Beach, CA

What it is, How it works

Hair testing is now seen as an effective instrument for identifying drug and alcohol consumption. Hair captures a long-term history of alcohol and drug use by embedding biomarkers within the strands of growing hair. Hair collected near the scalp provides an alcohol and drug detection period of up to three months. Collecting hair is straightforward, hard to tamper with, and easy to transport.

A sample consisting of a 1.5-inch segment with around 200 hair strands (comparable in thickness to a #2 pencil) closest to the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG tests, add-ons, or tests exceeding 10 panels, 150mg is advised. It is recommended to use a jeweler's scale for specimen weighing. If scalp hair cannot be sourced, a comparable amount of body hair can be used. 'Head hair' refers exclusively to scalp hair, whereas 'body hair' pertains to all other types (e.g., facial, axillary).

Process Overview

The primary steps involved in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails an initial processing phase where a sample is integrated into a lab's system, confirming that it was sealed and sent correctly, assigning a LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody.

Screening involves a preliminary assessment for drugs of abuse. Although cost-efficient in negating drug usage in most samples, a positive result requires confirmation for legal admissibility. Samples deemed presumptively positive during Screening need secondary verification.

If Screening indicates a presumptive positive, further hair is extracted from the original specimen for the Extraction phase. At this point, drugs are drawn out at a much lower concentration from hair compared to other techniques (e.g., urine or oral fluid), which is what makes hair drug testing complex.

Confirmation of any positive Screening outcome is carried out via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as necessary. The complete lab process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair findings and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests reveal drug use up to 90 days, unlike urine tests, which have a shorter timeframe for detection.
• Hard to deceive: Hair drug tests are significantly more difficult to manipulate, lending the results greater reliability.
• Shows historical patterns: This test reveals drug usage trends over time rather than just recent consumption.

Limitations:

• Can't detect recent usage: Detectability of drugs in hair takes approximately 5-7 days.
• Expense: Hair drug testing usually incurs higher costs compared to alternative drug testing methods.
• Result variability: Aspects such as hair shade and individual growth variations can impact drug metabolite concentrations in hair samples.

Note: Commonly termed "hair follicle tests", these tests actually analyze the hair strands instead of the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Kings Beach, CA, hair follicle testing offers distinct advantages over traditional urine tests. Hair tests outshine in reliability and detection accuracy, tracing drug use back 90 days.
