For these tests, kappa is 0.64, suggesting moderate-substantial agreement. However, McNemar’s chi-squared is 22.88, with 1 degree of freedom and P < 0.001.

From the data available it is not possible to say which test is better - the additional positives on Test 1 could be either true or false positives, depending on test specificity.
