Hair Follicle Drug Testing - Marshalltown, IA

What it is, How it works

Seen as an effective method, hair testing identifies drug and alcohol use, preserving a historical record within the fibers of growing hair. When hair is clipped near the scalp, it can provide an approximate 3-month detection period for substances. The process is straightforward to collect, hard to tamper with, and simple to transport.

Securing a 1.5-inch segment, roughly 200 strands of hair (pencil-thick #2), achieves 100mg, ideal for both screening and validation. For EtG, additional tests, or over 10-panel examinations, 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't available, an equivalent body hair sample can be taken. "Head hair" exclusively refers to scalp hair, while "body hair" includes all other types excluding the head (like facial, axillary, etc.).

Process Overview

Four principal steps constitute the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step, checking sample seal and shipping integrity, allocating a Laboratory Accessioning Number (LAN) randomly, and completing any missed data entry not handled by the electronic chain of custody system.

Screening performs an initial assessment for drug abuse but a positive indication requires further validation for courtworthiness. Any samples yielding a presumptive positive in Screening must undergo a secondary confirmation.

If a presumptive positive appears in Screening, more hair is taken from the primary sample for Extraction. Here, drugs are isolated from hair at lower concentrations compared to methods like urine or oral fluid, which is why it's the most challenging test to execute.

Confirmation of positive screenings uses GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptively positive samples are washed as deemed necessary. From Accessioning through Confirmation, the full laboratory procedure is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use up to 90 days, compared to shorter durations for urine tests.
• Hard to manipulate: Cheating a hair drug test is nearly impossible, boosting result accuracy.
• Shows usage patterns: Offers a timeline of drug use across a period, not just recent consumption.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair after 5-7 days.
• Expense: Hair tests are generally more costly than other drug testing methods.
• Result variations: Variations can occur due to hair color and individual hair growth rates, affecting metabolite concentration.

Note: Although termed "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.
