Hair Follicle Drug Testing - Rockport, CA

What it is, How it works

The growing use of hair testing has proven to be an effective means for identifying the presence of alcohol and drugs. Hair offers a prolonged record of substance usage by embedding biomarkers within the fibers of the strand. When collected near the scalp, it can reflect drug and alcohol intake over a period of roughly three months. Hair collection is straightforward, moderately resistant to tampering, and convenient for transportation.

A 1.5-inch hair sample, consisting of around 200 strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield approximately 100mg, the optimal amount for both screening and confirmation. For EtG and other extended panel tests above 10 panels, a 150mg specimen is advised. It's suggested to measure this on a jeweler's scale. If scalp hair is unobtainable, a similar volume of body hair can be collected. Our reference to head hair pertains strictly to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within the lab system. This step confirms the sample’s secure sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any unfilled data entry needed that's not included by an electronic chain of custody system.

Screening is a preliminary check for substance abuse. Despite being a cost-effective method to exclude drug use in most samples, any positive findings in Screening must undergo confirmation to be acceptable in legal proceedings. Presumptive positives from Screening necessitate a follow-up confirmation.

Should screening results suggest probable positivity, additional hair is extracted from the original sample for further Extraction. Within this phase, drugs are extracted from hair, although at lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening particularly challenging.

Confirmation of any positive Screening outcome employs techniques like GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples, if necessary, are cleansed before confirmation. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the standards of ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests which offer a shorter time frame.
• Resistant to manipulation: Cheating on a hair drug test is highly challenging, ensuring more reliable outcomes.
• Historical insight: This test can illustrate a timeline of drug consumption over time, not merely recent use.

Limitations:

• Inability to detect immediate use: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug testing is typically pricier than alternative drug testing methods.
• Result variability: Variables like hair color and individual differences in hair growth may influence drug metabolite levels in hair.

Note: Although commonly known as "hair follicle tests," the evaluation targets the hair strand itself, rather than the follicle beneath the scalp.
