How Accurate is Your Bloodwork?

Could be pretty accurate, but ever thought about those ranges and what really makes up 'normal'?

Ranges on bloodwork vary per lab, and are based on the bell curve of pathology. It's why lab ranges may read as normal despite you not feeling your best. There's a lot of talk now about 'tightening the ranges', and that's done to help explain exactly that- to potentially offer more of a reason, based on physiology and clinical knowledge, of why things are not quite right. 

For example:

  • High HDL cholesterol, our good cholesterol, is good, but when it gets too high like over 100 (give or take depending on the health care professional), it can be seen as a general inflammatory marker (so extra searching is required)
  • Carbon dioxide, not always one of the most popular markers, generally speaking, is tightly controlled. One of the ways to tell if you need to put a yoga class or meditation into your routine is if your levels are over 26. You need to breathe better- now take a deeep breath.. hold.. that a few more times. 
  • Vitamin D3, on the contrary a very popular lab test, where there's a pretty big range from 30-100. Generally people feel best (I've had patients where various symptoms were greatly improved too) at around 40-50 ng/mL, and then there's quite a bit of research for even higher levels at around 50-70+ for heart disease and cancer. There is such a thing as too much vitamin D (it pulls calcium into the system which can make bones more brittle), so best to get tested first, and retested if you're on a dosing schedule. 

Questions? I've got answers! I'm certainly glad to discuss further as labs can provide a plethora of information.
