I came by this great video explaining basic routine blood tests and what all the markers mean. This is not kidney specific, however it is very informative about what's going on in your body. Like a lecture to a class - not a sales pitch. Copy and past in search bar: Blood Test Training with Dr. Ritamarie (clickfunnels.com)
Let me know your thoughts!
The link clickfunnels.com just takes you to a home page for that internet provider and not to the video that you speak of.
I saved that link to my computer and it plays for me, but if I google "Blood Test Training with Dr. Ritamarie (clickfunnels.com)" it took it me to the website. Anyway, I think that I was watching the seminar free on facebook that day. Sorry. But I found one a little shorter, like 40 min. on you tube called Dr. Ritamarie Hidden gems in your annual lab test. I'm sure this includes many I watched. The one I watched she went thru almost everything listing in a cbc lab test, what it's for etc., then also talked about thyroid, magnesium and others. I learned a lot. I think she's got a seminar on her sight and a program but she's not pushy or anything like some. Hope that helps.
Oh gosh, I meant facebook. Type that in facebook search bar not you tube!
