I don't really know where to post this. If I post in hypothyroid, they will likely kick it back to cholesterol. I believe they are related. I guess my question is, who has had a lab report with Small LDL-P? And what were your numbers? According to the lab ranges, I fear I may be in a bit of trouble. I have never had Small LDL-P show up on a blood lab, only LDL. My triglycerides have been high for many years. I know this test to distinguish LDL is somewhat new, but I would surely appreciate any advice.
