Hair Follicle Drug Testing - Vacaville, CA

What it is, How it works

Hair analysis is now regarded as a highly effective method for detecting drug and alcohol consumption. Hair offers a comprehensive record of substance use by encapsulating biomarkers within the hair strands during their growth. When collected from near the scalp, hair can provide up to a 3-month window to detect alcohol and drug usage. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (approximately the width of a #2 pencil) close to the scalp yields about 100mg of hair, the optimal amount for analysis and verification. For additional tests, such as EtG or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the sample on a jeweler’s scale. If scalp hair cannot be collected, an equal quantity of body hair may be used. By head hair, we imply scalp hair only. Other body hair includes any additional types (facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary entry of a specimen into a laboratory's records. This step ensures the sample is intact and shipped correctly, allocates a unique LAN (Laboratory Accessioning Number), and completes any necessary data input missing from an electronic chain of custody.

Screening entails an initial rapid assessment for drug presence. While Screening is an economical approach to eliminate drug use in most samples, a positive result must be confirmed to stand in legal settings. Any samples preliminarily positive in Screening require additional verification.

If a sample is initially positive during Screening, more hair is taken from the original sample for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or saliva), which is why hair drug screening is the most challenging technique to execute.

Confirmation of any positive Screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive results undergo washing before Confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use up to 90 days, unlike urine tests which cover a shorter detection span.
• Challenging to falsify: It is exceptionally hard to manipulate a hair drug test, ensuring more reliable results.
• Tracks usage patterns: It can illustrate a pattern of substance use over time, not just immediate usage.

Limitations:

• Cannot detect recent usage: It typically takes 5-7 days for drugs to become visible in hair.
• Expense: Hair drug tests are often pricier than alternative drug testing methods.
• Variable results: Elements like hair color and personal differences in hair growth can alter drug metabolite levels in hair.

Note: Despite often being labeled as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp
