Lateral flow tests are very accurate, which means that only a very small proportion of people who do not have coronavirus will receive a positive result (false positive). The tests have lower sensitivity, but they are better at picking up cases when a person has higher viral load, and more contagious, hence the need to test frequently.
When used in combination with other measures such as Personal Protective Equipment (PPE), washing hands regularly and social distancing, these tests further reduce the risk of transmission. Easy Lateral flow devices do not require a laboratory to process the test. The devices are designed to be intuitive and require minimal training to operate.
