Blood Chemistry
Is there a best time of day for a person to test their ketones or can it be any time but around the same time each day? I’ve seen a range of 0.5 to 3.0, but what is considered therapeutic?
Chris Kresser: There’s not really an ideal time of day, but if someone wants to make sure they’re in sustained...
Do you use SpectraCell testing? I’m interested in testing micronutrient imbalance with my clients. What lab or tests do you recommend here?
Chris Kresser: All of the ones that we covered in the blood chemistry unit. We talked about a lot of...
I’m looking for an alternative to the True Health Diagnostic testing for the metabolic work-up. I am a chiropractor and True Health at this time does not allow chiropractors to order. Is there another lab I could look into that is close to the True Health testing for the metabolic workup including fructosamine, fasting insulin, etc., for blood sugar dysregulation?
Dr. Amy Nett: Great question. I like True Health Diagnostic, mostly for the cardiovascular disease risk assessment. I think True...
Thanks for providing the Blood Chemistry Manual. It looks like something we’ll be referring quite often. Can you make it available as a downloadable e-book or PDF for easy reference?
Chris: We have chosen not to do that for a couple reasons. One is that we update those markers fairly...
Listened to the Aristo Vojdani interview. I’m wondering if Cyrex Array 3X has the antibodies to gliadin epitopes that are only IgA as opposed to IgG. Is there any reason to believe that some tolerance could be restored to occasional gluten? Thinking that if the immune reactions are mucosal and have not broken through the gut lining so to speak, the avoidance of gluten for a longer time period may be four to six months as well as focus on foods, prebiotic, probiotics, and supplements, and they maintain a healthy gut lining including vitamin D, zinc, and EFAs. Could we regulate TH2 and TH3 cell behavior?
Okay, next question from Jessica. “Listened to the Aristo Vojdani interview. I’m wondering if Cyrex Array 3X has the antibodies...
General recommendations for physical labs or markers that would be advisable for general health for men and women to monitor. Should they be customized?
Another question from Kyle. “General recommendations for physical labs or markers that would be advisable for general health for men...
This is about high ferritin and low hemoglobin and/or hematocrit. This patient had a history of severe Crohn’s, which is now in remission. Had been on sublingual methylcobalamin awhile. His ferritin is 149, but then all the iron markers were low, MCV is a bit high, and then MCH, MCHC, and RDW were all normal.
Chris Kresser: Next question from Tessa. “This is about high ferritin and low hemoglobin and/or hematocrit. This patient had a...
Iron deficiency anemia and anemia of chronic disease—if they have both, is it safe to supplement with iron or just treat the iron underlying cause?
Chris Kresser: Yes. In that situation, you could give iron for sure. Especially if the soluble transferrin receptor is high,...
Chris mentioned that the tests for zinc and copper have relatively low sensitivity. With this in mind, how reliable is zinc-copper ratio and does the information that it acquires worth the extra cost? I use Principal Labs for my cash patients and the costs from these two additional tests is $141. The comprehensive panel that includes the majority markers is $199.
Chris Kresser: Justin is asking about zinc and copper imbalance in the live call. “Chris mentioned that the tests for...
Is elevated homocysteine common in menopausal women, and when do you just assume it is elevated because of menopause versus other concerns?
Amy Nett: Next question from Amber. Amber says, “I have a 56-year-old female patient. No major health concerns but she...
