Brief Summary

The present Diagnostic Accuracy study aims at experimentally validating the use of a rapid salivary test to detect SARS-CoV-2 infection in both symptomatic and asymptomatic individuals as a preliminary approach to a mass screening program. The study is based on a consecutive recruitment of both patients showing symptoms probably associated with COVID-19 (i.e., cough, dyspnea, fever) and asymptomatic patients with a low risk phenotype. The expected number of recruited individuals is 100. The experimental test is a prototype of salivary test based on the Lateral Flow Immunoassay technique and is able to detect the presence of SARS-CoV-2 in saliva, especially the Spike protein (S). The comparison is represented by the nasopharyngeal swab, the gold standard of COVID-19 diagnosis. Patients will undergo both salivary immunoassay and nasopharyngeal swab, thus the outcome assessors are blinded, since the results of the rRT-PCR analysis require at least 6 hours before being available. The main outcomes are sensibility and specificity of the rapid salivary test, when compared with the gold standard (nasopharyngeal swab).

Outcome Measures

Primary Outcomes (2)

  • Sensibility

    TP/TP+FN (TP= True Positive; FN = False Negative)

    Salivary test will be interpreted after 10 minutes; the nasopharyngeal swab after 6 hours; sensitivity recorded through study completion, an average of 2 months.

  • Specificity

    TN/TN+FP (TN= True Negative; FP= False Positive)

    Salivary test will be interpreted after 10 minutes; the nasopharyngeal swab after 6 hours; specificity recorded through study completion, an average of 2 months.

Study Arms (2)

Symptomatic patients

EXPERIMENTAL

Patients with symptoms associated with COVID-19, i.e., dyspnea, cough, fever, etc.

Diagnostic Test: rapid salivary test

Asymptomatic subjects

ACTIVE COMPARATOR

Asymptomatic patients with low risk phenotype, that means patients with a previous negative swab, no relatives affected by COVID-19 and with reduced social interaction within the last two weeks.

Diagnostic Test: rapid salivary test

Masking Details
The rapid salivary test will provide results within 5-10 minutes, while the rRT-PCR performed on nasopharyngeal swab shows results only after 6 hours, thus the outcome assessor of the experimental test is blinded
