The Neocollins antigen test will not detect two bars for a common cold, but only for a cold that is actually infected with the Neocollins virus, as explained below. The Neo-Crown virus antigen test is very similar to a pregnancy test in that there are two lines on the antigen test card. If both the C and T lines show red or purple bands, the result is positive; if there is a red or purple band on the C line but not on the T line, the result is negative; if there is no red or purple band on the C line, and only the T line is colored or colorless, the result is inaccurate and the test should be repeated. The accuracy of the new coronavirus antigen test cannot reach 100%, and it is not a clinical substitute for nucleic acid test results.
