Description
Pulse oximetry measures how much oxygen the haemoglobin in your blood is carrying. This is called the oxygen saturation and is a percentage (scored out of 100). It’s a simple, painless test which uses a sensor placed on your fingertip. If oxygen levels are below 88 percent, that is a cause for concern
At-home testing is a growing part of health care that, like telemedicine, has captured more and more interest during the COVID-19 pandemic. Direct-to-consumer (DTC) at-home tests now include a diverse range of test types offered by numerous companies, providing customers and patients more options than ever before.
