Hair Follicle Drug Testing - Carmet, CA

What it is, How it works

Hair testing has emerged as an influential resource for identifying drug and alcohol consumption. Hair reveals a prolonged history of alcohol and drug use as biomarkers are captured within the fibers of the growing hair. When collected near the scalp, hair can offer a detection period of up to about 3 months for alcohol and drugs. It is easy to gather, somewhat hard to tamper with, and simple to transport.

A 1.5-inch sample comprising approximately 200 strands of hair (roughly the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg is advisable. We suggest measuring the sample with a jeweler’s scale. If scalp hair is not obtainable, an equivalent quantity of body hair can be collected. When mentioning head hair, it refers specifically to scalp hair. Body hair pertains to any other hair type (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of entering a sample into the lab’s system. This task involves ensuring the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any other necessary data entry not encompassed by an electronic chain of custody system.

Screening implies an initial hurried examination for drugs. Though Screening provides an economical means to exclude drug use for most samples, a positive screening must be verified to be legally acceptable. Any samples shown as presumptively positive in Screening necessitate a subsequent confirmation.

If a sample is deemed presumptively positive during the Screening phase, additional hair is drawn from the original sample and readied for Extraction. In this step, drug compounds are isolated from hair at lower concentrations than seen in other methods (like urine or oral fluid), highlighting why hair drug screening presents the greatest challenge.

Confirmation of any positive screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS technology. All presumptively positive samples undergo washing before confirmation as required. The complete process from Accessioning through Confirmation is reviewed in accordance with both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which have a shorter detection window.
• Hard to manipulate: Hair drug tests are challenging to falsify, enhancing result reliability.
• Offers historical insight: It can show a pattern of drug use over time, beyond mere current use.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair roughly 5-7 days post-use.
• Costly: Hair drug tests tend to be more expensive than alternative methods.
• Result variations: Variables like hair color and individual hair growth discrepancies can impact drug metabolite levels in hair.

Note: Frequently called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Carmet, CA, the advantages of hair follicle over urine tests are manifold. Hair tests provide greater detection periods and are nearly impossible to beat, offering a more complete view of one's drug history. This longitudinal detection places hair tests ahead for employers enforcing rigid anti-drug measures.

The durability of detection—up to 90 days—of hair testing stands in stark contrast with the shorter window available in urine screening. As a result, organizations can assure themselves of behavioral patterns over a more extensive timeframe, a key consideration for trustworthy employee assessments.

Extended Detection Window
