Interesting article in Family Practice News about a study at Mayo CLinic using a sponge on a string to diagnose Barrett's.
Swallow EsophaCap and wait 10 minutes and then pull the expanded (25mm) sponge back through the esophagus and then do PCR testing on 2 DNA markers.
Initial study was 100% specific and 100% sensitive and no endoscopy needed.
