Hello and welcome to HCM. Thank you for your query. I completely understand your concern, but please also note and discuss with your employer, court judge or the laboratory personnel, that a diluted urine report could also be due to the following causes: -Liver problems: when the liver is not functioning correctly, there is a possibility that the kidneys may manufacture crystal clear urine. Poor digestion, bloating and decreased appetite are some of the common symptoms linked with liver diseases -Diabetes: urine excreted appears diluted with excess fluid and hence, the urine color in DI patients is crystal clear -Well hydrated individual: when the urine is diluted and clear, it indicates healthy hydration levels -Others (substance abuse) Please rule out all causes before a conclusion of adulteration (substance abuse) is made. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
