Guest guest Posted February 20, 2008 Report Share Posted February 20, 2008 This is not medical advice just my opinion on what my sources say. It also depends on their testing methods and chemicals used. Best to ask your lab. Drugs that can cause false positive measurements include colchicine, iron, oxidizing drugs (for example, iodine, bromides, and boric acid), and reserpine. There are also several foods and dietary supplements that can cause this. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 20, 2008 Report Share Posted February 20, 2008 A stool hemoccult/blood test is just that....a stool test that tests for hemoccult/blood or hidden blood in the stool.

Guest guest Posted February 20, 2008 Report Share Posted February 20, 2008 I don't see why iodine would affect that. There shouldn't be blood in your stool at all. Iodine is iodine.

Guest guest Posted February 20, 2008 Report Share Posted February 20, 2008 The iodine might be reacting with the chemicals used to test for the blood. Vitamin C can give a false negative (you could be bleeding & have it not show up on the test). B God Bless America!

Guest guest Posted February 22, 2008 Report Share Posted February 22, 2008 Steph...you missed the point. I know iodine is iodine, and there shouldn't be blood in the stool, I'm not that stupid, but due to diverticulosis and celiac disease, I sometimes have occult blood in the stool. Some diseases and conditions cause blood in the stool, and periodic checks can signal further testing. According to some sources, if iodine is injested before doing the stool hemocult blood test, it can react with the test kit and give off a false positive (show that there is blood in the stool when there is not). I was just wondering if anyone had any experience with this. By you saying that you didn't see why iodine would affect that, are you saying that this is not true??? If that's the case I will keep on taking my iodine before hemocult stool testing that I get periodically, which is due next week. http://www.nlm.nih.gov/medlineplus/ency/article/007008.htm http://www.labtestsonline.org/understanding/analytes/fecal_occult_bloo d/sample.html I think I will take your comment to my doctor next week and see what he says anyway as you do seem to be quite knowledgable about iodine. Thanks.

Guest guest Posted February 22, 2008 Report Share Posted February 22, 2008 My doctor did mention not taking vitamin C. BTW not many people know that it can create a false negative. Iron should not be taken also, as it can create a false positive. Thanks.

Guest guest Posted February 22, 2008 Report Share Posted February 22, 2008 No I wasn't saying it wasn't true. I really don't have any knowledge of iodine reacting with a test. If you are concerned then stop the iodine before the test for a few days.
