National Screening Centers Launches Revolutionary 90-Panel Oral Drug Test
National Screening Centers is proud to announce the launch of its newest and most advanced drug testing solution yet: the Oral ZT-90, a game-changing 90-panel saliva-based drug test designed for modern workforce compliance and safety.
Unlike traditional testing methods that require restrooms, supervision, and invasive procedures, the Oral ZT-90 offers a fast, private, and secure alternative. This test collects a saliva sample in less than one minute, requires no bathroom visit, and delivers lab-verified results in just two days.
“This is more than just a drug test—it’s a smarter, cleaner, and more respectful way to maintain a safe workplace,” said a spokesperson for National Screening Centers.
Key Benefits of the Oral ZT-90 Test Include:
Non-Invasive Collection: No need for urine samples or direct observation.
Unmatched Privacy: Reduces discomfort and increases cooperation among test subjects.
Tamper-Resistant: Virtually eliminates cheating with synthetic urine or substituted samples.
Highly Accurate: Utilizes patented lab technology with CLIA and COLA accreditation.
Time-Efficient: Collection takes less than a minute—perfect for busy workplaces.
Ideal for industries that demand safety and compliance, such as transportation, construction, healthcare, and corporate environments, the Oral ZT-90 empowers businesses to make smarter hiring and workforce decisions while respecting the dignity of their employees.
This breakthrough testing option is now available through National Screening Centers, Houston’s trusted partner for professional and reliable screening services.
