Hello, I'm ~riley. I wanted to let you know that I removed one or more external links you added to Blood urea nitrogen because they seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page or take a look at our guidelines about links. Thank you. ~ riley  ( talk  ) 08:28, 23 November 2019 (UTC)
