Hair Follicle Drug Testing - Avocado Heights, CA

What it is, How it works

Hair testing is now recognized as an effective means for detecting drug and alcohol use. Hair retains a long-standing record of alcohol and other substances by embedding biomarkers within the growing hair fibers. When gathered near the scalp, hair can offer up to about a 3-month detection range for alcohol and other drugs. Easy to collect, challenging to adulterate, and straightforward to ship, hair serves as a beneficial specimen.

A 1.5-inch sample of nearly 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will produce 100mg of hair, the optimal sample size for screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, it is recommended to use 150mg of the specimen. Employ a jeweler’s scale to weigh the specimen accurately. If scalp hair is not available, an equivalent amount of body hair can be used. When referring to head hair, it exclusively means scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Overview

There are four core stages in the laboratory handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary handling of a specimen into a lab’s framework. This process includes ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any necessary data entry not captured by an electronic chain of custody system.

Screening serves as an initial swift examination for drugs of abuse. While Screening offers a cost-efficient method to dismiss drug use in most samples, a positive screening must be validated to be considered admissible in court. Any samples demonstrating presumed positive results in Screening require additional confirmation.

If a sample indicates a presumed positive result during Screening, further hair is extracted from the initial sample and prepared for Extraction. In this step, drugs are separated from hair at considerably lower concentrations than in other methodologies (e.g., urine or oral fluid), highlighting why hair drug testing is among the most complex methodologies to carry out.

Confirmation of any positive screening results is achieved using GC/MS, GC/MS/MS or LC/MS/MS. All samples presumptively positive are washed before confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a shorter detection time frame.
• Hard to manipulate: It is exceedingly challenging to subvert a hair drug test, resulting in more accurate outcomes.
• Offers historical insight: It can reveal a drug use pattern across a span of time, not just recent usage.

Limitations:

• Cannot detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug tests often cost more than alternative drug testing methods.
• Result variations: Variables such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the analysis is performed on the hair strand rather than the hair follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Avocado Heights, CA, hair follicle testing offers a distinct advantage over traditional urine tests when it comes to evaluating drug use.
