Accredited Drug Testing provides thorough hair follicle testing solutions in Walnut, California. If you're looking for drug or alcohol hair analyses, our expertise in hair assessments spans multiple cities Nationwide. For valid testing, approximately 1.5 to 2 inches of hair from the scalp or body is typically necessary. Hair tests can evaluate drug, alcohol/ETG, or be tailored for specific requests.

Recently, hair follicle testing has been increasingly favored for drug assessments. It's now commonly required by employers, judicial systems, and Substance Abuse specialists, often replacing urine tests. Hair testing is ideal for organizations enforcing zero-tolerance drug policies, legal institutions, and probation monitoring. Its advantage is tracing drug use up to 90 days, collected under supervision, making it largely tamper-proof. For detecting recent drug use within five days, urine tests remain the gold standard.

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence by trapping markers within the fibers of the developing hair strand. When gathered near the scalp, it can reflect substance use for a timeframe of up to roughly three months. The collection process for hair is straightforward, it's somewhat challenging to tamper with, and it is convenient to send.

An ideal examination and verification sample consists of a 1.5-inch segment from about 200 hair strands, which is comparable to the thickness of a #2 pencil, and is taken nearest to the scalp providing 100mg of hair. When conducting EtG, extended panels, or tests exceeding 10 panels, a specimen of 150mg is advised. It's suggested to measure the sample using a jeweler’s scale. In the absence of enough scalp hair, an equivalent volume of body hair can be collected. Head hair is specifically scalp hair, while body hair includes all other types, such as facial and axillary hair.

Procedure Outline

The primary steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial steps of processing a specimen into a lab's system. This step ensures that the specimen was correctly sealed and delivered; a random LAN (Laboratory Accessioning Number) is assigned, and any further data entry not captured by an electronic chain of custody system is completed.

Screening performs an initial cursory evaluation for substances of misuse. Screening is an economical approach to exclude drug usage in the bulk of specimens; however, a positive screen must be confirmed to have validity in legal contexts. Samples presumed positive in Screening necessitate a subsequent confirmation.

Upon a presumptive positive outcome in the Screening phase, additional hair is drawn from the original sample and prepped for Extraction. This phase involves removing drugs from hair at a much lesser concentration compared to alternative methods (such as urine or oral fluid), underscoring the complexity of hair drug analysis.

Positive outcomes from screening are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are washed before confirmation, as required. The entire lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair label and according to ISO / IEC 17025 standards of accreditation.

Benefits of hair drug screening:

  • Extended detection period: Hair tests can identify drug use for up to 90 days, whereas urine tests provide a shorter detection window.
  • Hard to deceive: Cheating a hair drug test is very challenging, leading to more reliable outcomes.
  • Yields historical information: This test can outline substance use patterns over time, rather than just recent use.

Drawbacks:

  • Incapable of detecting recent use: It requires around 5-7 days for substances to become detectable in hair.
  • Price: Generally, hair drug tests incur higher costs than other methods of drug testing.
  • Result variations: Elements like the color of the hair and personal differences in hair growth can impact the levels of drug metabolites within the hair.

Clarification: While commonly known as "hair follicle tests," the analysis centers on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Compared to traditional urine tests, hair follicle testing offers unmatched accuracy and reliability in Walnut, CA. While urine tests can detect recent drug use, hair tests reveal a broader timeline, effectively covering up to three months.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
