Hi Den, I have just had the lovely experience of being mailed what someone else called the Sh1T kit, now available to all we lucky over-60s as a routine test. The leaflet which came with it was very helpful, it said that we could be recalled or resampled for a number of reasons including minute specks of blood in the sample which could have many causes. I was clear but I am reassured (as I am sure you and Mr Den are) that we are in the system, which is better than not being tested at all and not knowing if anything is potentially happening. I wish you and Mr D well, I hope it turns out to be something and nothing.
I am really sorry that FF feels that we are not helping each other, or posting erroneous information. I do agree that false info is dangerous - and in my experience if someone has posted something incorrect re health, six others have jumped up and corrected it - but the mutual support on here is so valuable in times of worry. We may not all be clinicians but we have our own experiences and this is a great way to share our worries and concerns. We can't always do it in the family, it's good to be able to share.
