Signal Quality

With every biomarker and insight result, Spren API will return a quality score to indicate the overall quality of the data signal received by the API. The score will be returned in the result object from the Biomarker and Insight results GET endpoint and will be returned as a status object, like all the other insights and biomarkers. For more information on the status object and how that's formatted, visit our Spren API Overview page.
