What are the Differences Between Occult Blood and Latent Blood?

There is no difference between occult blood and latent blood, as both terms refer to the same thing. The presence of occult blood or latent blood in test results indicates that there is damage to red blood cells in the digestive tract, resulting in a small amount of bleeding. However, there are no obvious signs of bleeding visible to the naked eye. In such cases, further tests are needed to identify the underlying cause and provide treatment accordingly.

1. Distinction between Occult Blood and Latent Blood

There is no distinction between occult blood and latent blood; they are simply two names for the same symptom. In the past, it was commonly referred to as occult blood, but nowadays, it is more often called latent blood. Bleeding in the digestive tract or urinary system occurs when red blood cells rupture due to their prolonged stay in the body. While red blood cells may not be detectable, their components can be, resulting in a positive latent blood test.

2. Causes of Occult Blood and Latent Blood

There are various causes of bleeding in the digestive tract, including hemorrhagic gastritis, gastric and duodenal ulcers, hemorrhagic necrotic enterocolitis, ulcerative colitis, and malignant tumors of the digestive tract.

3. Treatment of Occult Blood and Latent Blood

Treatment for occult blood or latent blood should be tailored to the specific cause identified through further investigation using gastric or colonic endoscopy. It is also important to maintain healthy eating habits, eat regularly, avoid overeating, consume plenty of fresh fruits and vegetables, and steer clear of spicy, greasy, and stimulating foods.
