Chris Kresser: Yeah, so that was through the, from the beginning of the year all the way through the end of this year, more comprehensive thyroid panel. They used to just do total T3 and total T4 and TSH as a starting point and then I would add free T3 and free T4 and thyroid antibodies for patients that I thought needed it. And then I’ve also added PTH and calcitriol and serum folate, which I didn’t typically include before. So those have increased the price.
Really, you just have to make the decision based on your patient population and your way of doing things. So for me, I just found that I was ordering those thyroid follow-up tests more often than not, and that it was helpful to have them up front rather than waiting for the follow-up. And then the PTH and calcitriol were additions as I did more research on vitamin D and determining biological D deficiency. Folate was something that I wanted to have in addition to FIGLU. So we could, because I was seeing an increasing number of people with elevated homocysteine who had normal B12 levels. But depending on your patient population and who and what you think they can handle financially, it may make sense to take off those markers and pare it down a little bit and then just order those as follow-up tests if you think it’s required.
