Hair Follicle Drug Testing - Diamond Bar, CA

What it is, How it works

Hair testing is acknowledged as an effective method for identifying drug and alcohol consumption. It offers a long-term record of substance use by capturing biomarkers within the strands as they grow. When taken near the scalp, hair can provide a detection window for alcohol and drugs lasting up to about 90 days. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch strand sample containing roughly 200 strands (approximately the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the ideal amount for screening and confirmatory purposes. For EtG, additional tests, or tests beyond 10 panels, 150mg is advised. It is best to weigh the sample using a jeweler’s scale. If scalp hair is not available, you may collect an equivalent quantity of body hair. "Head hair" specifically refers to scalp hair, whereas "body hair" pertains to other hair types (such as facial, underarm, etc.).

Process Overview

The processing of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step where a sample is incorporated into a lab’s system. This involves checking that the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and entering any data not included by an electronic custody process.

Screening is a preliminary, rapid assessment for substance abuse. Although Screening is an economical approach for eliminating drug use in most samples, a positive result requires confirmation for legal acceptability. Any samples indicating presumptive positives in Screening need further confirmation.

If a sample tests as presumptively positive during Screening, additional hair is taken from the original sample and undergoes preparation for Extraction. In this phase, drug compounds are extracted from hair at much lower concentrations than other methods (e.g., urine or saliva), which makes hair drug screening a highly challenging technique to conduct.

Confirmation for any positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The entire process from Accessioning to Confirmation is subjected to a review under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can uncover substance use for up to 90 days, in contrast to urine tests that have shorter detection periods.
• Cheating prevention: Cheating a hair drug test is nearly impossible, ensuring more reliable results.
• Historical insights: It provides a trend of substance use over a duration, rather than pinpointing recent use alone.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to show up in hair.
• Expense: Hair drug tests are typically more costly than alternative testing methods.
• Result variations: Aspects like hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although commonly termed as "hair follicle tests", the assessment actually examines the hair strand and not the follicle beneath the scalp.
