Diagnosis 

The use of digital technologies for monitoring health-related symptoms started with the development of personal digital devices such as smartphones and smartwatches. These devices can measure vital signs (e.g., heart rate, blood pressure) and movement (e.g., counting steps). These measurements can produce simple health data logs that can provide valuable information for HCPs about patients’ health status. Technological advances made in-home laboratory tests possible (Figure 1). The development of biosensors enables a broader range of diagnostic tests to be performed remotely (Figure 2), resulting in more accurate monitoring of patients’ conditions and impacting the diagnostic process for patients, clinicians and the healthcare system: 

  • It can inform patients about their medical condition and can give concrete early warning signs.
  • It allows clinicians to make an early diagnosis. 
  • It can reduce the need for health resources.
