Hair Follicle Drug Testing - Prairie City, SD

What it is, How it works

Utilizing hair testing is increasingly recognized as an efficient method for identifying drug and alcohol consumption. Hair offers a prolonged historical record of alcohol and drug use by embedding biomarkers within the strands as they grow. When samples are taken close to the scalp, they can demonstrate alcohol and drug use for up to three months. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.

A sample of the hair measuring 1.5 inches, roughly 200 strands (similar to a #2 pencil in size), and closest to the scalp yields 100mg, which is perfect for assessment and verification. For EtG, additional tests, or panels above 10, 150mg of the sample is preferred. It is advised to measure the sample on a jeweler's scale. In cases where scalp hair cannot be obtained, a comparable amount of body hair may be used. References to head hair pertain solely to scalp hair. Body hair includes any other forms of hair (such as facial or axillary).

Process Overview

Key procedures in laboratory testing for drug results encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing phase of a specimen into the lab's system. This stage involves confirming proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing data entry requirements absent in the electronic chain of custody system.

Screening carries out an initial assessment for substance misuse. Despite being an economical means to exclude drug usage in most cases, a positive result in screening necessitates confirmation to be legally valid. Samples that appear positive in Screening necessitate an additional verification.

For samples deemed positive in Screening, additional hair is retrieved from the primary sample and readied for Extraction. At this juncture, the extraction of drugs from hair occurs at a significantly lower concentration relative to other methods (e.g., urine or oral fluid), making hair drug testing a challenging methodology.

Confirmation of positive screening results is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation as necessary. Each laboratory phase from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use up to 90 days previously, whereas urine tests offer a shorter timeframe.
• Hard to falsify: Tampering with hair drug tests is immensely challenging, ensuring result accuracy.
• Records long-term use: Offers a timeline of drug consumption over time, not just recent use.

Limitations:

• Cannot detect immediate use: Drugs take approximately 5-7 days to be traceable in hair.
• Expense: Hair drug tests are typically more costly than alternative drug testing techniques.
• Result discrepancies: Variables like hair pigment and personal hair growth characteristics may influence drug metabolite levels in hair.

Note: Although often labeled as "hair follicle tests", this analysis examines the hair strand rather than the follicle beneath the scalp.
