Is there any info on what the loss of specificity is if a Pe protocol is used in terms of diagnosis of aortic dissection? Also, intralesional thrombosis wouldn't be contraindicated, would it? And, last, why remove IVC filter? Thanks.

In the C3 Chest Pain Summary around minute 25:14, the speaker notes that iron can cause falsely positive guaiac tests. The literature, however, suggests otherwise. This study (apparently the only known RCT) found only 1 falsely positive test in 326 samples of healthy individuals (78) taking ferrous sulfate. Thank you for any additional commentary.
