Why Do Total Tests Performed Not equal Total Positive Tests plus Total Negative Tests?

• Test results may be received up to 24 hours after they are received by the lab, so positive and negative totals for a given day may trail the total number of tests taken.
• Some test results are returned as inconclusive and require a person to re-test. Inconclusive tests are not included in either the positive or the negative test totals.
