This work introduces a wireless, solid-state, portable, and automated device capable of semi-continuously measuring the total ammonia (ammonia (NH3) and ammonium (NH4 + )) levels of fluids, including biological samples. This device reliably measures the total ammonia of biological samples (e.g., urine) faster than current ammonia quantification techniques.
Current frameworks for evaluating diagnostic tests are constrained by a focus on diagnostic accuracy, and assume that all aspects of the testing process and test attributes are discrete and equally important. Determining the balance between the benefits and harms associated with new or existing tests has been overlooked. Yet, this is critically important information for stakeholders involved in developing, testing, and implementing tests.
