Blood tests: The BIG differences between “ normal ” and ideal

It is not uncommon for there to be considerable differences between what you are told is “normal” for a blood test and what is ideal. The differences are big enough to impair health, even increase risk for numerous diseases, even death. Here is why labs and your doctor often provide grossly misleading interpretations of blood tests and how you can decipher the real answers. Among the examples: Vitamin D—The lab says that blood levels of 25-hydroxy vitamin D should be between 10-30 ng/ml. How did they get that value? Easy: They tested the blood levels of many people who live indoors, wear clothes, and don’t consume foods like liver that contain vitamin D. No surprise: Testing a population deficient in vitamin D provides the appearance that low vitamin D blood levels prevail. The problem is that this deficient level is regarded as “normal”—it is not. We therefore aim for the ideal level which is 60-70 ng/ml based on observations such as maximal suppression of parathyroid hormone (PTH) and maximal avoidance of cancers. TSH—Lab reports state that a thyroid stimulating hormone, TSH, level should be 0.2-5.5 mIU/L. (Some labs specify 4.5 mIU/L as the upper limit of normal.) But why? Once again, populations were tested who were largely iodine-deficient and exposed to numerous thyroid toxins such as bisphenol A (BPA), perfluorooctanoic acid, and hundreds of others that we know from numerous toxicological studies have potential to disrup...
