Hair Follicle Drug Testing - San Rafael, CA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair serves to archive a prolonged record of alcohol and drug presence by capturing biomarkers within the hairs as they grow. When obtained near the scalp, hair can furnish approximately a three-month detection timeframe for alcohol and drugs. The sample collection is straightforward, moderately resistant to tampering, and simple to transport.

A 1.5-inch length of roughly 200 hair strands (comparable to a #2 pencil in size) nearest to the scalp yields 100mg, which is the ideal quantity for analysis and validation. For EtG, additional tests, and/or panels beyond 10, a 150mg sample is advised. It is prudent to determine sample weight using a jeweler's scale. In the absence of scalp hair, similar body hair can be taken. Here, head hair refers exclusively to scalp hair, whereas body hair refers to hair from other regions (facial, axillary, etc.).

Process Overview

The process of a drug test in the laboratory comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary integration of a sample into the laboratory’s system. This step includes verifying that the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and filling in any additional details absent from an electronic chain of custody system.

Screening entails an initial scan for illicit drugs. Although Screening is an economical method to dismiss drug use for most samples, a confirmed positive outcome is needed for legal acceptability. Samples with a presumptive positive result in Screening necessitate subsequent confirmation.

When a sample registers as presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, the concentration of drugs extracted from hair is lower compared to other techniques (like urine or oral fluid), rendering hair drug screening the most challenging procedure to execute.

Confirmation of any positive outcome from Screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive undergo necessary cleansing before confirmation. The complete process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specifications and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug intake for up to 90 days, unlike urine tests with a limited timeframe.
• Hard to falsify: Cheating on a hair drug test is extremely hard, ensuring higher reliability of the results.
• Offers historical insight: It reveals a pattern of substance use over time, not just recent usage.

Limitations:

• Incapable of recent detection: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Higher expense: Generally, hair drug tests incur more costs than alternative drug testing methods.
• Variation in results: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being commonly known as "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
