The reason for this study is to collect nasal swab samples from symptomatic patients to help make new tests for detecting COVID-19 and flu, and/or make current tests better. The BinaxNOW™ COVID-19 Ag /Flu A & B Combo Card test used in this study is investigational. The results of the testing done in this study will not be given to you.

The purpose of this research study is to help detect a heart attack by measuring a protein called troponin. A company named Quidel is sponsoring a research study to see how a blood test that they make helps to diagnose heart attacks.

The sponsor of this study is LightDeck Diagnostics. LightDeck has developed the LightDeck COVID-19 Antigen Test. This test operates outside the body (in-vitro). This is a point-of-care (POC) diagnostic test. It is intended to diagnose COVID-19 in people suspected of having COVID-19 by their healthcare provider within twelve (12) days of symptom onset, or in people who have no symptoms.

Troponin I (cTnI) is a protein that is found in the heart muscle. When someone has a heart attack or other injury to the heart muscle, increased levels of cTnI can be measured in the blood and testing for cTnI in blood is used to help diagnose a heart attack and other heart conditions.

The purpose of this study is to use an investigational device called the Atellica® VTLi™ test system to test a substance in your blood called troponin that may help with the diagnosis of a heart attack
