PCR vs. Rapid Testing: What’s Right for You?
Understanding the Difference and Choosing the Right Option for Your Needs
Whether you’re testing for employment, legal compliance, travel, or personal peace of mind, choosing the right type of test matters. At National Testing Services (NTS), we offer both PCR and Rapid Testing to meet a variety of needs. Here’s what you need to know about each option—and how to decide which one is right for you.
What is a PCR Test?
PCR (Polymerase Chain Reaction) tests are laboratory-based tests that detect genetic material from a virus or other biological substance. They are highly accurate and sensitive, often used for:
Confirmatory testing (after a positive rapid test)
Medical or diagnostic purposes
Legal or official documentation
Travel requirements (in some cases)
Turnaround Time:
PCR results typically take 24–72 hours, depending on the lab processing speed and type of sample (e.g., saliva, nasal swab, urine).
What is a Rapid Test?
Rapid tests are designed to deliver results quickly—usually within 15–30 minutes—and are used for screening and immediate decision-making. These tests are available for both:
Drug & alcohol screening (e.g., urine or saliva)
Some infectious diseases (like COVID-19)
Rapid testing is ideal when:
You need same-day results
The test is for employment or pre-screening
You’re managing random or post-accident testing for DOT or non-DOT compliance
