Hair testing is now regarded as an effective approach for identifying drug and alcohol consumption. By embedding biomarkers within the growing hair strand's fibers, hair can offer a prolonged history of alcohol and drug usage. If sampled near the scalp, hair can present a detection timeframe of up to roughly three months for alcohol and drugs. It's easy to collect, relatively tamper-proof, and convenient to transport.
A sample measuring 1.5 inches with approximately 200 strands (comparable to the thickness of a #2 pencil) nearest the scalp amounts to 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a total of 150mg is suggested. Utilizing a jeweler's scale for weighing the sample is advised. Should scalp hair be unavailable, an equivalent amount of body hair is an alternative. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (such as facial and axillary hair).
Process Overview
Four primary steps make up the laboratory process for drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially processing a sample within a lab's system. It involves ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody.
Screening consists of a preliminary swift check for substance abuse. Although Screening is budget-friendly and eliminates drug usage in most samples, a confirmed screen is necessary for legal acceptability. Samples testing presumptively positive during Screening need subsequent confirmation.
When a sample is preliminarily positive during Screening, further hair is extracted from the original sample for Extraction, where drugs are extracted at much lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening the most challenging process.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all positive samples are washed as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: "Hair follicle tests" often refer to the test involving the hair strand rather than the follicle within the scalp.
When comparing hair follicle tests to traditional urine testing in Norway, OR, the former stands out due to its superior detection accuracy. Hair tests minimize false negatives, proving more reliable and comprehensive.
Additionally, hair testing's extended detection window provides more substantial insights into long-term substance use history, offering employers a better risk assessment tool than urine tests.
A significant advantage of hair follicle testing in Norway, OR, is its extended detection window. With a detection period of up to 90 days, it gives employers a broader view of an individual's substance use history.
