Hair Follicle Drug Testing - Dayville, OR

What it is, How it works

Hair analysis is widely recognized as an effective means for detecting substances like drugs and alcohol. The strands of hair can encapsulate biomarkers within the fibers as the hair grows, providing a prolonged history of substance exposure. When hair is taken near the scalp, it can reveal alcohol or drug use within an approximate three-month period. The collection of hair is straightforward, relatively resistant to tampering, and simple to transport.

Collecting a sample of 1.5 inches in length, consisting of roughly 200 strands (comparable in size to a #2 pencil) closest to the scalp results in about 100mg of hair, which is the optimal quantity for both preliminary and confirmatory testing. For EtG tests, additional screenings, or when testing more than 10 panels, a specimen amounting to 150mg is advised. A jeweler’s scale should be used for weighing the specimen. Should scalp hair not be available, an equivalent portion of body hair can be used. Note that when referring to head hair, it pertains exclusively to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary hair).

Process Overview

The laboratory procedure for a drug test result comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where the sample first enters a laboratory’s framework. This step verifies the sample’s proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and might involve additional data entry that isn’t captured by an electronic chain of custody system.

During Screening, the sample undergoes an initial check for common drugs of abuse. This stage is cost-effective for eliminating drug usage in most samples; however, positive screenings need further verification to be legally viable. Samples that test positive during Screening need secondary confirmation.

Should a sample appear positive in Screening, extra hair is extracted from the original sample for further analysis in the Extraction phase. Here, substances are extracted from hair strands at far lower concentrations than other testing methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Confirmation of positive Screening outcomes is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples showing presumptive positivity undergo washing as necessary. The comprehensive laboratory workflow from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can recognize substance use for as long as 90 days, unlike urine testing, which has a briefer detection span.
• High difficulty of test evasion: Cheating a hair drug test is quite challenging, enhancing the credibility of the results.
• Presents usage history: This method can show a history of drug usage over time instead of only the most recent use.

Limitations:

• Inability to detect recent usage: It can take between 5-7 days for a drug to be noticeable in hair samples.
• Expense: Hair drug tests usually cost more than other methods of drug testing.
• Variable results: Factors including hair color and personal hair growth differences can influence the concentration of drug metabolites detected in hair.

Note: Although frequently termed "hair follicle tests", the examination actually evaluates the hair strand rather than the underlying scalp follicle.
