“The Abbott coronavirus test hailed by President Trump and used by the White House failed to detect infected samples in a large number of cases that were caught by a rival firm, a preliminary study says.”
“The speedy Abbott test, which is supposed to determine in five to 13 minutes whether a person has the virus, missed a third of the positive samples found by the diagnostic company Cepheid when both tests used nasopharyngeal swabs, said the study done by a group from New York University. It missed more than 48 percent when both firms’ tests used dry nasal swabs. The former penetrates deeply into the nasal passages, while the latter is less invasive.”
And
“Before a Senate committee last week, National Institutes of Health director Francis Collins testified that the rapid Abbott test had a 15 percent false negative rate, an apparent reference to unpublished data from the Cleveland Clinic”
Medicynical note: Trump strikes out again. First it was a hoax, then going away like a miracle, then the game changer hydroxychloroquin, then drink bleach and then the apparently not accurate enough Abbott quick test. That’s our leader.
Medicynic 
And……Abbot is the test he is relying on to keep himself safe. There’s a sucker in every crowd.
