How the Hair Drug Test Process Works

Getting a hair drug test at Fastest Labs of West Chester is straightforward. Walk in at your convenience or request an appointment online, where “Hair Drug Test” is a selectable service option in the scheduling form.

During collection, our certified collector takes approximately 90-120 strands of hair, and 1.5 inches in length collected directly from the test subject’s scalp, then sends the sample to one of our accredited laboratory partners. Results are typically available within 24 hours to 1-2 days.

How Hair Follicle Drug Testing Works

Hair follicle drug testing analyzes the hair strand for drug metabolites that become incorporated into the hair as it grows, creating a chronological record of substance use over time. The standard sample is approximately 90-120 strands of hair, 1.5 inches in length, collected directly from the scalp by a certified collector.

Detection Window & Limitations

The test detects drug use within the past 90 days. Because drugs typically don’t appear in hair until 5-7 days after use, very recent use may not be captured. Hair testing demonstrates historical exposure within the detection window; it doesn’t confirm impairment at the time of the test. When head hair is insufficient, body hair may be used as an alternative and can detect drug use within the past year.

One reason hair testing is widely trusted: there are no known reliable methods of cheating a hair drug test.

Panel Options

We offer hair follicle drug testing in 5, 10, 12, 14, 16, and 18-panel configurations. The right panel depends on your situation.

A 5-panel hair test screens for amphetamines, cocaine, marijuana, opiates, and PCP. Higher panel counts add substances such as benzodiazepines, barbiturates, methadone, expanded opiates, and fentanyl. Employers typically follow their drug-free workplace policy or regulatory requirements when selecting a panel. For court-ordered drug testing and other legal matters, hair follicle drug testing is an accepted method.

Who Uses Hair Drug Testing in West Chester, PA

Our clients include individuals, employers, attorneys, courts, government agencies, and military clients. Each group relies on the 90-day detection window for different reasons.

Employers use pre-employment screening with hair testing to support zero tolerance drug policies with an extended look-back period.
Legal professionals and courts use hair drug testing in child custody, probation, and DUI proceedings where a longer detection window is required.
Parents may request hair drug testing when they have concerns about ongoing substance use by a family member.
Individuals can walk in for personal testing without an employer or court requirement.

Paired with a urine drug test, this method can provide a comprehensive, accurate look at drug usage across both short and extended timeframes.

Hair Testing Compared to Other Drug Test Methods

Different situations call for different testing methods. Hair follicle drug testing covers up to 90 days of history, making it well-suited for pre-employment screening and legal proceedings where a longer look-back period matters. Urine testing remains the standard for federally mandated and DOT compliance programs, and it’s often paired with hair testing when both recent and extended history are relevant. Saliva testing detects recent drug use, sometimes within hours of ingestion, making it a practical choice after an accident or when there’s reasonable suspicion of immediate impairment.

At Fastest Labs of West Chester, we offer urine, saliva, nail, and sweat and skin drug testing alongside hair follicle drug testing, so we can match the method to your specific need.

Pennsylvania Drug Testing: What Employers & Individuals Should Know

Pennsylvania doesn’t require private employers to conduct drug testing, but employers are free to build and enforce their own programs. Given Pennsylvania’s medical marijuana law, a clearly written drug-free workplace policy that explicitly addresses marijuana prohibition is especially important for safety-sensitive roles. Employers can also benefit from a documented testing program when workers’ compensation or unemployment compensation claims arise.

Hair follicle drug testing is recognized in Pennsylvania legal proceedings, including family court and probation matters, though admissibility and specific requirements vary by case. If you have questions about how testing fits your situation, our team can help you choose the right approach.
