Hair Follicle Drug Testing - Lexington Hills, CA

What it is, How it works

Hair testing is regarded as a significant method for identifying drug and alcohol consumption. Hair captures a lengthy record of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair offers up to an approximately three-month detection scope for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and conveniently shipped.

A sample measuring 1.5 inches with around 200 strands of hair (comparative to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for testing and validation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of hair is advised. It is suggested to measure the hair sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair may be gathered. When mentioning head hair, it specifically means scalp hair, and body hair includes all other types (facial, axillary, etc.).

Process Overview

The four primary phases in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step of entering a sample into the lab system. This consists of checking if the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and filling in any other data details not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. It is an economical method to largely eliminate drug use from most samples, but positive results from Screening need confirmation to be valid in court cases. Any samples that test positive in Screening will need a follow-up confirmation.

When a sample shows a presumptive positive result in Screening, more hair is extracted from the initial sample and readied for Extraction. In this stage, drugs are extracted from hair at considerably lower amounts as compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is particularly complex.

Confirmation of any positive found during Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that tested presumptively positive are cleaned before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 norms.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a narrower detection period.
• Hard to deceive: Cheating a hair drug test is very challenging, thereby enhancing accuracy in results.
• Reveals historical data: It offers a timeline of drug use over a time frame, not just recent consumption.

Drawbacks:

• Fails to detect recent intake: It takes about 5-7 days before drugs appear in hair.
• Expenses: Hair drug tests typically carry higher costs than alternative drug testing techniques.
• Result inconsistencies: Variables like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the examination focuses on the hair strand rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Lexington Hills, CA, presents several advantages over traditional urine tests. Firstly, hair testing offers a superior detection window, capable of identifying drug use up to 90 days prior, as compared to the shorter timeframe of urine tests. This allows for a comprehensive look at an individual's substance use pattern.

Besides its extended detection period, hair follicle testing in Lexington Hills is inherently more reliable. It is virtually impossible to manipulate test results, unlike with urine tests, where tampering is a known issue. The accuracy and dependability of this method make it a valuable tool for employers and legal authorities alike.

Extended Detection Window

The hair follicle drug test in Lexington Hills, CA, is renowned for its extensive detection window, capturing up to 90 days of substance use history. This lengthy period enables employers to gain a thorough understanding of an individual's habits, which is critical during hiring or routine checks. This extended timeframe provides a level of insight not accessible through more limited testing methods.

This wide detection span is a cornerstone advantage, offering unparalleled insight into an applicant's or employee's substance history. By offering such a comprehensive overview, employers can make more informed and responsible decisions regarding workforce management and potential new hires.

Tamper-Resistant Testing Method

In Lexington Hills, CA, the reliability of the hair follicle drug test is a significant factor due to its resistance to tampering.
