Table 2 Real time PCR Ct data of N1, N2, and N3 genetic regions and viral load

From: Could asymptomatic carriers spread the SARS-CoV-2 infection? Experience from the Italian second wave

  Asymptomatic (n = 13) Symptomatic (n = 11) 95% CI p-value
Region N1 mean Ct (range) 34.13 (24.4–38.7) 31.4 (18.3–39.1) –7.229 to 1.709 ns
Region N2 mean Ct (range) 33.8 (25.5–38.7) 31.1 (16.9–39.5) –7.529 to 2.342 ns
Region N3 mean Ct (range) 29.12 (24.4–35.7) 30.8 (17.7–39.3) –2.800 to 6.138 ns
Viral Load mean copies/mL (range) 3.09E + 04 (84.95E + 01–3.09E + 05) 2.88E + 06 (2.94E + 00–2.8E + 07) –1635430 to 5522968 ns
  1. Mean real time PCR Ct data and mean viral load related to 13 asymptomatic subjects (7 males, 6 females, median age 46.9, range 21–80) and 11 symptomatic subjects (6 males, 5 females, median age 63.9, range 22–96)
