1 Milk inhibited target RNA at 12.5%. Milk was diluted to 6.25%, and still inhibited 3 of 3 reactions, and was subsequently diluted to
1.6%, which showed 100% positive target lines. Internal positive control was active and visible at 12.5% milk.
2 Mucin inhibited target RNA at 100 mg/mL. Mucin was diluted to 50 mg/mL and showed 3 positives out of 3 attempts (100%).
Internal positive control was active and visible at 100 mg/mL of Mucin.
3 Tobramycin and Amoxicillin positive samples were initially tested without RNA by mistake. These were repeated and yielded 100%
expected results.
4 Eucalyptus Oil was used as a substitute for Halls Triple Soothing Cough Drops.
FDA SARS-CoV-2 Reference Panel Testing
The evaluation of sensitivity and MERS-CoV cross-reactivity was performed using reference material (T1), blinded samples and a
standard protocol provided by the FDA. The study included a range finding study and a confirmatory study for LoD. Blinded sample
testing was used to establish specificity and to corroborate the LoD. Testing was performed using the Accula SARS-CoV-2 Test with the
Accula Dock. The results are summarized in the table below.

Clinical Evaluation
Testing of Contrived Samples
Thirty (30) negative samples and 30 positive contrived samples were tested with the Accula SARS-CoV-2 Test. Negative samples were
collected from consented healthy volunteers under IRB approval. A throat swab and a nasal swab was collected from a donor and eluted
