Non-Invasive Strep Detection: Saliva PCR Testing for Kids

Non-Invasive Strep Detection: A Better Experience for Children and Families

Diagnosing strep throat in children has traditionally relied on throat swabs, an uncomfortable process that often triggers fear, gagging, and anxiety. Modern, science-driven innovation is transforming diagnosis: non-invasive strep detection using saliva delivers accurate results without discomfort, making pediatric visits more manageable for both children and parents.

Why Non-Invasive Testing Matters

Traditional throat swabs often cause gag reflexes, watery eyes, and distress. Many children resist the procedure, leading to repeat sampling and amplified stress for families and healthcare providers. Saliva-based non-invasive testing completely removes these challenges, improving cooperation and ensuring reliable sample collection.

How Saliva-Based Strep Detection Works

SalivIQ™ Strep A uses advanced molecular technology to detect Group A Streptococcus DNA directly from a small saliva sample. Key features:

✅ Two simple collection steps
✅ No specialized training required
✅ Suitable for clinics, urgent care, school health programs, and community healthcare settings

Comfort for Pediatric Patients

Parents consistently report:

✅ Better cooperation
✅ Less fear and anxiety
✅ Children feel in control without mouth swabs
✅ This transforms a traditionally stressful process into a predictable and painless experience.

Rapid Results at Point-of-Care

Saliva-based qPCR technology provides results in as little as 22 minutes, allowing:

✅ Faster treatment decisions
✅ Reduced repeat visits
✅ Minimization of symptom progression

Why Clinicians Choose Non-Invasive Testing

Clinicians and clinics benefit from:

✅ Accurate point-of-care results without lab delays
✅ Simplified workflow and minimal staff training
✅ Reduced repeat sampling and improved patient throughput
✅ Integration into urgent care, pediatric clinics, and school health programs
✅ Supports proper antibiotic stewardship

Reducing Antibiotic Misuse

Improper antibiotic prescriptions are a growing global concern. False negatives from traditional tests often lead clinicians to prescribe antibiotics unnecessarily, increasing risks of allergic reactions, contributing to antibiotic-resistant bacteria, and raising healthcare costs — estimated at $21.3M annually in pediatric insurance expenses. Accurate, non-invasive strep detection supports proper antibiotic stewardship.

Take Action: Explore Non-Invasive Strep Testing

Throat Swab + Rapid Strep Tests	Saliva Collection + Rapid PCR Testing
In-office variability across providers	Self-collection by patient
Potential for inadequate swab collection by not reaching the tonsils or posterior pharynx	Consistent collection; only a small amount of saliva needed
Can create anxiety, a gag reflex, discomfort, and/or crying in children	Non-invasive for patients; fun for children
High bacterial load needed on swab to detect Strep A	Low bacterial load can be detected with rapid PCR
False negatives are common	Highly accurate – Test developed using clinical samples and formulated to be unaffected by salivary inhibitors or other organic matter
