Hello,

Foam in the urine is caused by protein, even in small amounts. If the dipstick is negative for protein then it is unlikely that you have abnormal amounts in the urine - there is always a small amount under normal conditions. To confirm the dipstick accuracy and to ensure all possible proteins were captured, you might consider doing either a 24 hr urine protein collection or a protein to creatinine ratio done on a spot urine. The high specific gravity means only that your urine is concentrated. This is not abnormal depending on how much you drink.

thank you very much for your reply.

Do you know what could cause my urine to become foamy if not kidney dysfunction?

Cheers
