Question 1

what are the causes for fuzzy-liquid stool with red blood?

Accepted Answer

Uncertain: Rectal bleeding may have a # of causes to include: hemorrhoids, anal fissure, fistula, polyp, cancer, or inflammation or infection of GI tract.  Your  physician can help to determine the cause.

Question 2

how can you carry out a stool blood test?

Accepted Answer

Use prepackaged kit: Most general medical doctors will have cards that allow you to take smear of your stool (fingertip or cotton swab) apply it to the card fold it closed and deliver it to your doctor for testing. The doctor or nurse will take a chemical solution, apply it to the card/stool  specimen and observe the reaction. If the reaction is positive a colonoscopy may be ordered, to look for cancer or polyps.

Question 3

is a false positive result in stool blood testing possible?

Accepted Answer

Yes: Occult blood tests based on testing for peroxidase activity generate false positives from eating meat, horse radish and iron intake.

Question 4

what should i do if i have a positive stool blood test result?

Accepted Answer

See your doctor: That is always abnormal.  You should see your doctor for further evaluation of this. It may be minor but you can't be sure until evaluated.

Question 5

what are the causes of false negative results in stool blood testing?

Accepted Answer

Bogus Testing: To be falsely negative would imply the presence of blood that has been missed.  Such an event commonly occurs with either a defective card, expired solution or poor sample.  Try using a different card and solution.  If there is a high suspicion of blood based on appearance or risk factors, a stool cell count can be done, a reagent test dropped into toilet water after defecating or fecal dna test.

Question 6

what could cause abnormal stool (blood)?

Accepted Answer

Get checked please: Blood per rectum, separate from or associated with stool regardless of age of the sufferer, is never normal. As such, and although the cause is likely easily explained (e.g. Hemorrhoids, anal fissure), it must be evaluated so serious pathology is not missed or diagnosis delayed.

Question 7

what does the stool blood test detect?

Accepted Answer

Blood: If you are referring to the standard fecal occult blood test in the office and it is done as a colon cancer screen.

Question 8

what should i avoid prior to taking the stool blood test?

Accepted Answer

Bismuth and Iron: Generally, if you can, you should avoid medications that contain bismuth such as pepto-bismol & iron tablets/pills for a few days.  This is because it can stain the stool black & sometimes give a false positive reading on the fecal occult-blood test (fobt).  If you're on blood thinners such as coumadin, (warfarin) aspirin, or plavix, let the doctor ordering your test know too but don't stop unless told to.

Question 9

in stool, can blood present itself as little solid pieces, or is it always a sticky or liquid consistency?

Accepted Answer

Varies: This can vary with the site of bleeding.  If from upper GI tract may simply present as black stools, if from terminal portions of colon may be bright red blood.  If in between, almost any type of presentation may occur, including clots which can appear similar to what you have described.

Question 10

what is the ez detect stool blood testing kit?

Accepted Answer

Limited usefulness: This is a home kit to detect blood in stool. However, except for its convenience there is no advantage as it is a lesser sensitive assay compared to current state of art technology "fecal immunochemical testing" for blood.  I am aware of only limited comparative data and it is not very supportive of ezd being comparable to clinical testing.
