Trusted Drug Screening offers comprehensive hair follicle drug testing services in Castroville, California. If you're seeking a hair drug or alcohol screening, we're experts in hair testing and provide services through centers nationwide. Typically, 1.5 to 2 inches of hair is required from the crown or other body areas. Hair samples are versatile for analysis, covering drugs, alcohol/ETG, and various tailor-made testing options.

In recent times, hair follicle drug testing has gained prominence as a drug testing method. It's increasingly preferred over standard urine tests by employers, courts, and Substance Abuse professionals. Zero-tolerance employers, courts, and probation officers favor hair tests due to their extended detection window, reaching up to 90 days, offering secure, monitored sample collections, making them difficult to manipulate. However, urine tests remain more accurate for detecting very recent usage within 5 days.

What it is, How it works

Hair testing is acknowledged as an effective means to identify drug and alcohol consumption. By embedding biomarkers in the fibers of the hair strand as it grows, hair provides an extended history of alcohol and drug use. When gathered near the scalp, it offers up to a three-month window of detection for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.

A sample measuring 1.5 inches in length, consisting of around 200 hair strands (similar in size to a #2 pencil) close to the scalp, yields approximately 100mg of hair, ideal for screening and confirmation. For EtG, additional tests, or assessments exceeding 10 panels, a specimen of 150mg is advisable. Using a jeweler’s scale is recommended for specimen weighing. If scalp hair isn’t available, a similar amount of body hair can be used. Here, head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the primary processing of a sample within a laboratory’s system. This step involves verifying proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening is a preliminary, cost-effective check for drugs of abuse, beneficial for ruling out drug usage in most samples. However, a positive screen mandates confirmation for court admissibility. Presumed positive samples in Screening require further confirmation.

In the event of a presumptive positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. In this process, drugs are isolated from the hair at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.

Confirmation of any initial positive result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples undergo washing prior to confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation is monitored under the CAP (College of American Pathologists) Hair classification and is accredited to ISO/IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug tests can detect drug use for up to 90 days, whereas urine tests offer a shorter detection period.
  • Hard to falsify: It is notably challenging to falsify a hair drug test, thereby enhancing accuracy.
  • Offers historical insights: It can depict a drug usage pattern over time, not simply recent use.

Limitations:

  • Incapable of detecting recent use: The detection of drugs in hair takes about 5-7 days post-use.
  • Expense: Generally more costly than other drug testing techniques.
  • Result variability: Factors like hair color and individual differences in hair growth can modulate drug metabolite concentration in hair.

Note: Often termed as “hair follicle tests,” the actual analysis is conducted on the hair strand and not the follicle beneath the scalp.
