Estimating clinical blood test results with smartwatch data
Clinicians and researchers have long been inspired by the potential of consumer-grade wearable sensors, such as smartwatches and smart clothing, to transform clinical care. However, to date, such technology has not resulted in many viable clinical applications – the recent ability to detect atrial fibrillation with smartwatches being a notable exception. Lukasz Kidzinski, a research associate in bioengineering, and colleagues at Stanford University have now developed machine learning models that also correlate smartwatch data with clinical lab tests, such as those that measure the amount of red blood cells.
Their studies elucidate factors that can improve the accuracy of such predictions, such as the use of personalized models versus population-level models. These findings open the door for new clinical uses for smartwatch data.
