It’s National Nurses Week

Join us in celebrating National Nurses Week as we acknowledge our appreciation and respect for the nursing professionals who work with laboratorians to deliver safe patient care. Nurses are often responsible for drawing patient blood samples that are delivered to the lab as well as performing point-of-care testing at the patient’s bedside. Laboratorians rely on nurses to perform testing that ultimately yields accurate results that contribute to good patient outcomes.

Candida Auris Presents Global Health Threat

The Centers for Disease Control (CDC) is reporting that Candida auris, an emerging fungus that presents a serious global health threat, is causing severe illness in hospitalized patients in several countries, including the United States. Patients can remain colonized with C. auris for a long time and C. auris can persist on surfaces in health care environments. This can result in the spread of C. auris between patients in health care facilities.
