Yes. Symptomatic Influenza A/B PCR testing is covered by Medicare, Medicaid, and most commercial insurance plans. NuWav bills insurance directly and offers transparent self-pay pricing for uninsured patients.
What specimens do you accept for flu testing?
We accept nasopharyngeal swabs, anterior nares swabs, and oropharyngeal swabs collected in viral transport media. Specimens should be refrigerated immediately after collection and held at 2–8°C until courier pickup or shipment to our lab.

Absolutely. NuWav serves pediatric practices throughout Fresno, California with kid-friendly anterior nares collection options that minimize procedural distress while maintaining PCR-grade sensitivity. Pediatric supply kits are available with every courier account.
