About "AACC Labora-Stories"

"Laborastories" are stories from the laboratory. Every day, laboratory experts make critical decisions about cancer treatment; manage chronic conditions like diabetes; and screen for high cholesterol levels, heart disease, and other disorders. Without advanced, high-quality lab medicine, patients might receive the wrong diagnosis, inappropriate treatment, or no treatment at all if the disease isn’t accurately detected and diagnosed. Trusted testing is essential to the high quality of care and quality of life for all patients.
