Chris Kresser: This is an example, including how to interpret it, is on slide number 21 in the DUTCH Test Part 2. I’m not sure exactly what week that was, but basically, with a healthy CAR, you should see a 350 to 600 percent increase in the first 30 minutes. You have the patient—you just order a typical ASI from any lab. Upon rising, the patient rinses his mouth. Have him put a glass of water right next to his bed, and immediately collect his saliva for two to three minutes. Then collect again at 30, 45, and 60 minutes, so that is four samples that you get in the kit. It’s best to drink maybe a little water in between those samples but not eat. He should get out of bed after collecting that first sample, and he should have some exposure to light because that is what activates the suprachiasmatic nucleus and the cortisol awakening response. When you get the results, as I said, you should see a 350 to 600 percent increase in the first 30 minutes no matter what units are used by that particular lab. On slide 21, I have an example of a CAR that was done by Mark Newman, who runs the Precision Analytical and the DUTCH test lab. You’ll see in the chart and the table that he hit 391 percent at 30 minutes, which is within that 350 to 600 percent range.

- If we were attempt a CAR, cortisol awakening response, hack with salivary cortisol, can you remind us of how to analyze the results? If you have a quick example or even a made-up one, that would be excellent.

- Woman coming in wants to prep herself for getting pregnant—35, birth control since 16. A few months ago, she went off birth control, experienced very bad acne, and so she went back on. Says the acne was the reason she went on when she was 16. This is a very common story of course, and I’m sure many of you have seen this lots of times. Done comprehensive blood. She looks pretty good outside of some functional iron deficiency, lack of protein in her diet, possible HCl, and electrolyte imbalances. Advised Paleo reset and then hormone testing. What tests do you suggest, and should they be done when on birth control or at some point went off the pills? I want to prep well before she goes off BCs so she can have less symptoms and then regulate her conception.
