The CRP test also measures inflammation that could be a recent cold, tissue injury,minor arthritis, etc...https://labtestsonline.org/understa.../hscrp/tab/test

I had one done pre-low carb when had arthritis in knee, IT Band pain, and bursitis in the hip...so got a highish score that the doctor then completely discounted. He said something along the lines older folks almost always have some inflammation in joints and the CRP is a "test in search of a problem”. Raging infections have scores in the thousands, but the slightly elevated ones could be a infected hang nail

Though "Happy Heart Month" is here, and Direct Labs has Cardio IQ for $109, the CRP and some other heart tests on special.

A number of Low Carb doctors, especially those with a patient base that can't afford or need a CardioIQ, will stick to the basics. Dr Ted Naiman is one, waist to height ratio the most powerful indicator of insulin resistance and it's free, the cheap off the shelf lipid panel where you check the HDL:Trig is sufficient ($24 at DL), and he would add fasting insulin. Not sure this is interview where he said he doesn't use the advanced lipid panel, but it is not mentioned at all in the short list of what he does use. https://youtu.be/YOoKd1QUD1c
