Drug & Alcohol Testing

A request for a drug test is on a piece of paper

SCSI is a TPA (Third Party Administrator) for DOT random and computer-generated consortium programs. SCSI conducts (on-site or in-office) DOT and Non-DOT drug and alcohol testing for:

  • Pre-Employment
  • Random
  • Return to Duty
  • Post Accident
  • Reasonable Suspicion
  • Follow Up


SCSI helps employers verify that employees, those being considered for employment, or employees suspected of working under the influence of drugs or alcohol, are substance free. Testing is also available to courts, school districts (for bus drivers & student athletes), parents, and individuals. SCSI assists you in determining which type of testing is most effective for your particular needs. Valid proof of identification (Photo ID) is required when testing is performed; those under the age of 18 must have a parent or guardian with them (with valid proof of ID) before testing is conducted. No appointment is necessary during regular office hours, Monday thru Friday, 8 AM to 5 PM.

Call 540-344-4676 for more information.


Hair Collection

Hair growth is fed by the bloodstream, the ingestion of drugs of abuse is revealed by analyzing a small sample of hair. Our testing method measures the drug molecules embedded inside the hair shaft, eliminating external contamination. Hair testing results cannot be altered with shampoos or other external chemicals.

A standard hair sample test (head hair) covers a period of approximately 90 days. The hair sample is cut as close to the scalp as possible and the most recent 1.5 inches are tested. It takes approximately 2 weeks from the time of the drug use for the affected hair to grow above the scalp. Body hair can also be collected, which can go back as far as a year.

Call 540-344-4676 to learn more.


Urine Drug Testing

Rapid/instant testing – 10 and 12 panel which produce results within three to five minutes of the collection.

Lab-based testing panels which produce confirmatory results within 24 to 72 hours of collection.

Medical Review Officer (MRO) validation of prescription medicine is required & included for DOT testing, and also available for non-DOT testing for additional fee.

In addition to the typical testing for illegal drug and prescription medications, urinalysis lab-based testing is available for these special types of specific substances not included in a regular testing panel:

  • Steroids
  • Nicotine
  • Alcohol
  • K2 Spice/Bath Salts
  • Gabapentin
  • Fentanyl
  • Kratom
  • Soma
  • Others available upon request

Call 540-344-4676 to set up testing.


Breath Alcohol Testing

This method of alcohol testing is the same technology used by most law enforcement agencies producing instant results. Our testing device automatically collects a breath sample, presents it to the fuel sensor for analysis and is broken down chemically. The outcome is converted to a digital breath alcohol concentration valve and is printed out. If alcohol is detected, the machine automatically goes into a 15-minute confirmation status.

Call 540-344-4676 for more information.


DNA Relationship Testing

A DNA paternity test compares a child’s DNA profile with that of the possible father to determine if there is a direct match.

Call 540-344-4676 to learn about DNA testing.

Lessons You Only Learn by Doing the Job If Part 1 was about learning the trade the hard way, this part is about paying for those lessons. No one starts out perfect in process serving or private investigations. Anyone who tells you otherwise is lying or hasn’t been doing this very long. Early on, I made mistakes—some small, some costly—but every one of them shaped how I work today. Mistake #1: Knocking Too Soon Early in my career, I thought effort meant action—drive up, knock, get it done. What I learned quickly is that patience beats urgency. Knocking on the door too soon tips your hand. Once a subject knows you’re there, the game changes. Observation should come first. Always. Mistake #2: Talking Too Much I learned the hard way that silence is a tool. In the beginning, I explained too much—who I was, why I was there, what the papers were about. That only created resistance. You don’t need to overshare. Be professional, be calm, and say only what’s necessary. Mistake #3: Trusting “Good Information” Without Verification Addresses were wrong. Work schedules were outdated. “He’s always home at night” turned out to be false. Early on, I trusted information because it sounded confident. Experience taught me to verify everything. Assumptions cost time, money, and credibility. Mistake #4: Underestimating Documentation I used to think I’d remember details later. You won’t. Dates blur. Times get fuzzy. Early mistakes in documentation taught me that your notes protect you. Courts don’t care what you meant to write—only what you actually did write. Mistake #5: Not Trusting My Instincts Soon Enough There were moments early on when something felt off and I ignored it—only to realize later my instincts were right. Experience sharpens intuition, but you still have to listen to it. If a situation feels wrong, it usually is. Mistake #6: Taking Things Personally This job puts you in the crosshairs of anger, fear, and blame. Early on, I took reactions personally. That’s a mistake. This work isn’t about you. Once I separated emotion from execution, everything improved—my safety, my accuracy, and my professionalism. The Biggest Lesson of All Every mistake reinforced one truth: this is a profession, not a side hustle. Process serving and investigations demand discipline, ethics, and accountability. Shortcuts don’t last. Reputations do. Those early mistakes made me better. They’re the reason I approach every case today with preparation, restraint, and respect for the process. Thirty-one years later, the fundamentals still matter—and they always will.he body content of your post goes here.

What 31+ Years in Process Serving and Investigations Really Teaches You Learning the Trade the Hard Way When I first stepped into the world of process serving and private investigations more than 31 years ago, there was no YouTube, no Facebook groups, no online directories, and no step-by-step guides. You learned by doing—or you didn’t last. I didn’t start out knowing everything. Nobody does. What I had was determination, curiosity, and a willingness to learn the trade the right way—by getting out there, making mistakes, paying attention, and adapting. Back then, process serving wasn’t about apps, GPS tracking, or instant skip traces. It was about observation, timing, patience, and knowing people. You learned quickly that knocking on a door was often the last step, not the first. You learned how neighborhoods worked, how people moved, when lights came on, when cars left, and when someone was likely trying not to be found. I learned early that this job isn’t just about handing someone papers. It’s about professionalism under pressure. You’re walking into tense situations. Emotions are high. People are scared, angry, embarrassed, or outright hostile. How you carry yourself matters. Your tone matters. Your judgment matters. There were no shortcuts. If you messed up, the court didn’t care why—you owned it. That responsibility shaped how I approached every serve and every investigation. Accuracy wasn’t optional. Documentation wasn’t optional. Integrity wasn’t optional. As I expanded into private investigation work, the lessons only deepened. Surveillance taught patience. Interviews taught listening more than talking. Skip tracing taught persistence. Every assignment reinforced the same truth: this field rewards those who take it seriously and exposes those who don’t. Over the decades, technology has changed, laws have evolved, and expectations have grown—but the fundamentals haven’t. You still need to know how to read situations. You still need to stay calm. You still need to be ethical. And you still need to remember that every case represents real people and real consequences. Looking back, I’m grateful I started when I did. Learning the trade the hard way forced me to develop instincts you can’t download and skills you can’t fake. It’s why I’ve lasted over three decades in an industry that chews people up quickly. Today, when I work cases or support newer servers and investigators, I bring every one of those early lessons with me. This isn’t just a job—it’s a profession. And if you treat it that way, it will carry you a long time. Thirty-one years later, I’m still learning. But I’ll never forget how it started—one door, one decision, and one lesson at a time.
