Hair Follicle Drug Testing - Unga, AK

What it is, How it works

Hair assessments have emerged as an effective instrument in identifying drug and alcohol consumption. The fibers of a growing hair strand trap biomarkers, giving a prolonged retrospective view of substance use. When taken near the scalp, hair can deliver an approximate 3-month detection range for alcohol and drugs. It's straightforward to gather, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimum sample size for analysis and verification. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler’s scale to determine the specimen's weight. Should scalp hair be lacking, an equivalent portion of body hair may be harvested. The term head hair strictly indicates scalp hair. Conversely, body hair encompasses all other types like facial and axillary.

Process Overview

The laboratory evaluation of a drug test encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's preliminary processing into the lab’s protocol. It verifies proper sealing and shipping of the sample, issues a random LAN (Laboratory Accessioning Number), and completes any absent data entry if not previously supplied by an electronic chain of custody system.

Screening is a preliminary check for substance misuse. Despite being a cost-effective method to exclude drug usage in most samples, a positive result from Screening requires verification to be legally valid. All presumptively positive samples in this phase need further substantiation.

For samples testing presumptively positive at the Screening stage, additional hair is drawn from the original sample for Extraction. Here, drugs are extracted at much lower concentrations compared to other techniques (such as urine or oral fluid), highlighting why hair drug screening is among the most challenging methods to conduct.

Any positive result from screening undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before Confirmation if necessary. The comprehensive lab procedure from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reveal drug use up to 90 days back, whereas urine tests have a narrower detection period.
• Hard to deceive: Cheating on a hair drug test is quite challenging, which makes outcomes more reliable.
• Shows historical patterns: It offers insights into a timeline of drug consumption over extended periods, rather than just recent usage.

Limitations:

• Recent use detection is limited: Drugs take around 5-7 days to appear in hair.
• Expense: Hair drug testing usually incurs higher costs than other testing techniques.
• Result variability: Variables like hair color and personal hair growth differences can influence the concentration of drug metabolites present.

Note: Although referred to as "hair follicle tests", it is the hair strand examined, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
