Hair Follicle Drug Testing - Chehalis, WA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. The hair archives a long-term record of alcohol and drugs by embedding biomarkers within the strands' fibers. Hair collected from near the scalp can reveal drug and alcohol use for a span of up to 3 months. Collection of hair samples is straightforward, hard to tamper with, and simple to send.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for initial screening and further confirmation. For EtG, additional elements, and/or tests exceeding 10 panels, it is advised to collect 150mg of hair. We suggest using a jeweler's scale to weigh the sample. If scalp hair cannot be sourced, an equivalent volume of body hair may be used. By head hair, we mean scalp hair only. Body hair encompasses all different hair types (facial, axillary, etc.).

Process Overview

Drug testing in the lab is characterized by four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial stage where a sample is entered into the lab's system. It involves confirming that the sample was sealed and dispatched correctly, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any missing data entry that is not covered by an electronic chain of custody system.

Screening pertains to a preliminary swift assessment for illicit drugs. Though a cost-efficient strategy for ruling out drug usage in many samples, a positive finding in Screening must be validated to be accepted in court. Samples with a presumptively positive result in Screening do require further confirmation.

For presumptively positive samples in Screening, additional hair is extracted from the original sample to prepare for Extraction. At this point, drugs are separated from hair at a lower concentration than in other testing methods (e.g., urine or oral fluid), which makes hair drug testing the more challenging method.

Any positive result in Screening is further verified via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory journey from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug usage for a period stretching up to 90 days, whereas urine tests have a briefer detection span.
• Hard to manipulate: Hair drug testing presents significant challenges for cheating, thereby ensuring more reliable results.
• Offers historical insight: It can outline a pattern of drug use over a timeframe, rather than just recent use.

Limitations:

• Cannot discover recent use: Drugs take about 5-7 days to be detectable in hair.
• Expense: Hair drug testing tends to be more costly compared to other drug testing methods.
• Varied results: Aspects such as hair color and individual differences in hair growth can impact drug metabolite concentration in the hair.

Note: Although often identified as "hair follicle tests", the analysis involves the hair strand and not the follicle buried under the scalp.
