Endoscopy is a nonsurgical procedure used to examine the digestive tract. X - ray is more general imaging (not specifically for detailed digestive tract inspection like endoscopy). Hemoccult test is for detecting blood in stool (not a full digestive tract exam). Blood test checks blood components (not the digestive tract itself).
