Looking into this more, Trump tested negative on an antigen card, which is not a CDC-recommended method to determine infectiousness.
Buzzfeed -
"Abbott’s BinaxNow test
has a sensitivity rate of 97.1%, according to the company, meaning it will return false-negative results for about 3% of people who are infected and should have tested positive. The company also recommends that in patients who are beyond a week from when their symptoms started, negative results “should be treated as presumptive” and confirmed with a PCR test. “Negative results do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions,”
company documents state."
This likely means that Trump is still testing positive on PCR tests. Conley continues to release selective information in an attempt to get Trump back on the campaign trail.
