Hair Follicle Drug Testing - Essexville, MI

What it is, How it works

Hair analysis has emerged as a robust method for monitoring drug and alcohol consumption. Hair can offer a prolonged overview of alcohol and various drugs by encapsulating biomarkers within the strands of hair as it grows. When cut close to the scalp, it potentially reveals a detection span of nearly three months for drugs and alcohol. Hair samples are easy to collect, relatively challenging to tamper with, and simple to send.

A specimen of 1.5 inches, consisting of around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp, yields 100mg, which is the optimal quantity for both screening and verification. For EtG, additional testing, or panels exceeding 10, 150mg of specimen is advised. Utilize a jeweler's scale to measure the sample weight. If scalp hair is unavailable, an equivalent quantity of body hair can be used. "Head hair" refers specifically to scalp hair only, whereas "body hair" encompasses all other hair types (like facial or axillary).

Process Overview

The lab processing of a drug test sample comprises four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where a sample is first processed into the lab's system. This includes confirming the sample was sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and filling in any extra data entry absent from an electronic chain of custody.

Screening serves as an initial swift assessment for drug misuse. Although Screening is a budget-friendly way to exclude drug use in most samples, any positive screen must be corroborated for court validity. Samples that presumptively test positive in Screening demand further confirmation.

Should a sample be presumptively positive in Screening, additional hair is extracted from the initial sample to prepare for Extraction. At this point, drugs are extracted from hair in far smaller concentrations than other methodologies (such as urine or oral fluid); this makes hair drug screening a particularly intricate method to carry out.

Confirmation of any positive result from Screening is done via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as needed. The entire lab process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the credentials to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can discover drug use up to 90 days, in contrast to urine tests which have a shorter detection period.
• Hard to deceive: Cheating a hair drug test is extremely difficult, making the results more trustworthy.
• Shows historical data: Hair drug testing can exhibit a pattern of drug use over time, rather than just recent use.

Limitations:

• Inability to detect recent use: It roughly takes 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests typically cost more compared to other drug testing methods.
• Variability in results: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis is performed on the hair shaft, not the follicle beneath the scalp.
