I went for the stool test on 16th of June and then on 18th June . I went for the stool test as I was seeing visible eggs of parasite in my stools of white color. So, I went for R/M and Occult Blood on 16th June where no Ova was present . So I forwarded this to the lab owner and he told me to repeat both the test again that top free of cost. So , today I went for the test and Occult Blood was positive with Roundworm in it. How can it be possible that within 2 days occult blood came turned from negative to positive as I am not suffering from Piles , Hemorrhoids etc... Then how can it turn positive within 2 days ? I think the lab owner has intentionally given a false report this time around. What's your take and advice in this case ? Reports attached . Should I go for colonoscopy according to 18th June report or not according to 16th June report ?
