Do false-positive COVID-19 tests repeat as positive with the same test?

An Arterian is wondering if other labs repeat positive SARS-CoV-2 tests. If yes, are false positives: 1) A luck of the draw or random function that will impact a certain percentage of test results depending on test specificity? Or 2) do the same negative samples always come up as false positives due to an inherent function of the test method and the specific patient sample (e.g., the test cross-reacting with other viruses in the sample)?
