Accredited Drug Testing offers thorough hair follicle drug screens in Keystone, Wisconsin. Whether you require a drug or alcohol test via hair, our expertise in hair testing is backed by centers nationwide, including in all major cities. Typically, a minimum of 1.5 to 2 inches of hair from the crown or body is sufficient for testing. Options include tests for drugs, alcohol/ETG, or tailored hair analyses.

Nowadays, hair follicle drug tests are increasingly used in drug screening processes. Many employers, legal systems, and substance abuse experts now favor hair tests over traditional urine tests. Hair follicle tests attract attention from employers with strict no-drug policies and are often mandated by courts and probation officers. They offer extended detection up to 90 days, involve an observed collection, and are highly secure against manipulation. Nevertheless, urine remains the preferred test for very recent drug use, up to the past 5 days.

What it is, How it works

Utilizing hair for drug and alcohol testing has become recognized as highly effective. Hair captures a long-term record of substance use by embedding biomarkers within the hair's fiber as it grows. When clipped near the scalp, it can reflect alcohol and drug consumption over roughly a 90-day period. Hair samples are easy to collect, resistant to tampering, and straightforward to transport.

For an optimum screening and verification, a 1.5-inch hair sample containing about 200 strands (similar in width to a #2 pencil) near the scalp provides 100mg, which is the preferred amount. For evaluations exceeding 10 panels or for EtG add-ons, 150mg is advised. It is suggested to weigh the hair sample with a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair may suffice. Note that head hair refers specifically to scalp hair, whereas body hair encompasses all other types like facial or underarm hair.

Process Summary

The primary stages in lab processing of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial step of integrating a sample into a lab’s system, including confirmation that it was sealed and sent correctly, assigning it a LAN (Laboratory Accessioning Number), and completing any manual data input lacking in an electronic custody trail.

Screening offers a swift preliminary assessment for the presence of drugs. Although it's a cost-efficient method to exclude drug use in most cases, results deemed positive require confirmatory testing for legal validation. Samples with apparent positive results in Screening necessitate a further confirmation phase.

Should Screening return a presumptive positive, additional hair from the original sample is subjected to Extraction. In this phase, drug substances are isolated from the hair, typically at lower levels than in other methods (such as urine or saliva), making hair analysis a complex procedure to perform.

Confirmation of any Screening positives employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive samples undergo a cleansing step before Confirmation as mandated. Each step from Accessioning to Confirmation is assessed under the guidelines of the CAP (College of American Pathologists) Hair classification and compliance with ISO/IEC 17025 standards.

Merits of hair drug testing:

  • Extended detection range: Hair tests trace drug use back up to 90 days, unlike urine tests that offer a shorter detection span.
  • High tamper resistance: The integrity of hair drug test results is upheld, as tampering is notably challenging.
  • Chronological consumption data: It illustrates a pattern of substance use over time, beyond just recent ingestion.

Drawbacks:

  • Inability to identify recent intake: Drugs become noticeable in hair only after roughly 5-7 days.
  • Expense: Hair drug testing tends to be pricier compared to other forms.
  • Result variability: Aspects like hair pigment and personal hair growth variations can impact metabolite concentrations.

Clarification: Although commonly referred to as "hair follicle tests," the analysis focuses solely on the hair strand, not the follicle beneath the scalp.
