  • Generally black stool means bleeding from the upper gastrointestinal tract, the stomach or duodenum. The stool tends to be all black. If you are bleeding intermittently (small amount of blood), then you could have partly black stool.
  • And, YES, other cause leading to this appearance include food particles such as fruits, particularly bananas.
  • Stool can be tested for blood easily, by using "EZ Detect" test, available over the counter. If the test is positive, then these specks are blood
  • And, you may also stop eating fruits and bananas for few days and see if these black specks disappear
  • Generally, if the blood test is negative, they are of no concern

Let me know if you have any further questions

Ok small amounts of blood would still be partly black as in a section of it? Not black sand mixed in brown stool?? To clarify there are hundreds of thousands of black gritty particles. They stay gritty and do not change when mixed with water. I imagine if it was old blood being mixed with water would dissolve the particle into a smear. I do actually have ez detect here. If I just toss it in the toilet water (which is how it says) there's no blood. If I touch the stool to the strip (which it was NOT designed for) it is positive. Maybe from red meat I ate or chicken

  • Then it is negative for blood.
  • You will need stool analysis: A sample submitted to the lab for analysis which should also include blood testing for confirmation. This will give details of what these specks are. This test will require a request for analysis through your doctor
