In the spotlight this episode, Dr. Kahn answers a common patient question: "What are you checking for in the spot urine sample I left in the lab?" He demystifies urine tests, discussing their use in detecting albumin as a marker for endothelial damage, measuring oxidative stress, and assessing nutrient levels, with a particular focus on iodine. Dr. Kahn encourages listeners to consider asking their healthcare providers for these informative and widely available tests.
