COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection ().They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing, and give users a result within 5–30 minutes.
The TWA test uses an ECG measurement of the heart's electrical conduction using electrodes attached to one's torso. It takes approximately a half-hour to perform on an outpatient basis. The test looks for the presence of repolarization alternans (T-wave alternans), which is variation in the vector and amplitude of the T wave component of the ...

Health officials stress that at-home tests are a vital and accurate way of tracking COVID-19 infections but an initial negative test doesn't mean people are out of the woods.
The test uses a single drop of blood obtained from a finger prick and yields results in 20 minutes. The sensitivity of this test is 98.03% while the specificity is 99.56%. [1] This test is paired with an easy-to-use mobile app which allows a trained professional to generate an antibody test certificate for storing on a person's smartphone. [1] [2]
