Abstract
Laboratory testing can provide information useful to promote patient health literacy and ultimately patient well-being. The human state of mind involves not only cognition but also emotion and motivation factors when receiving, processing, and acting upon information. The cognitive load for patients acquiring and processing new information is high. Modes of distribution can affect both attention to and receipt of information. Implicit unconscious biases can affect whom and what patients believe. Positive wording and framing of information with salience for patients can evoke positive emotions. Providing patients with the gist, or essential meaning, of information can positively influence decision-making. What laboratorians provide as information helps to combat mis- and disinformation. Laboratorians can actively participate in measures to improve the patient experience in health care by developing and contributing to high-quality information to enable timely, meaningful communication and interpretation of test results.
