Brief Answer:
Probably due to drinking a lot of water to prevent stones.

Detailed Answer:
Hello and welcome,

I'm sorry you have been having this problem. If you have kidney stones I assume you drink a lot of water. And if you drink a lot of water, then your ETG test will be dilute.

I don't think your health problems in and of themselves are causing the ETG test problem. I wouldn't expect IBS to have an effect here. But the dilution by increased drinking (which is necessary given your history of stones)is likely doing this.

I hope this information helps. Please let me know if I can provide further information or clarification.
