Our study shows that adding laboratory markers enables the Cytosponge test to also be used to monitor the condition," Dr. Rebecca C. Fitzgerald of the University of Cambridge told Reuters Health by email. "Cytosponge was easy to implement, results were received within 6 to 11 days, and endoscopy was prioritized for 17% of patients found to be at high risk."
