Thanks for the answer.
First, not seeing a cardiologist in PA. I'm simply asking if I want to order labs directly from a place such as TrueHealthLabs.com or another one of the places you can go direct, but they specify certain tests (e.g., apoB) cannot be collected in NJ for testing. However, I can take that same form and drive over to PA and get my blood drawn. I'm not breaking any laws. It's the same draw whether it is LDL ( fairly useless metric these days) or apoB. It's what happens to that blood in the test.
I have extremely high cholesterol, but my last CAC (calcium) test and CCTA soft plaque of heart/arteries showed zero calcium and plaque. Some people have low LDL and high apoB. Doctors that are up to date with the latest science (which is now more than 10 or 15 years old) know to order apoB. But you would be amazed at the number of family doctors and cardiologist that a) don't know what apoB is or means; b) never order it for their patients to get a closer look a patient's lipid profile; c) refuse to order it if the patient asks. It is ridiculous. A family member had extremely high apoB after ordering the test and the primary care doctor said nothing about it.
I hate being that patient that has to rely on "Dr. Google", but apoB should be ordered for every patient as part of a lipid panel.
As far as coverage, you are correct. It is not covered. It costs $35. NJ BCBS deems it "experimental" and refuses to pay for it. But they will pay for a lifelong prescription of a statin that a patient may not even need. FFS is our health system broken.
Sorry for the rant. While Twitter is not always a reliable source, Dr. Thomas Dayspring (RU alum!) is one of the foremost lipidologists in the world. Here is a tweet, with a link to a study in The Lancet. Dr. Sniderman from Canada is another proponent of apoB testing, and so are numerous other MDs. Sorry for the long rant. I need to get my blood pressure checked.
Super interesting. Thanks for the explanation. I confess, I know nothing about ApoB as a prognostic marker of cardiovascular risk. The ones I think of are your traditional measures plus hsCRP (as an inflammatory bio marker) and the Framingham offspring study has some pretty compelling data on LDL particle size (ie very low density lipoprotein being the most likely to penetrate the Endothelium and build up vascular wall plaque)
Anyway, with all that said, I’m not sure why you are able to order ApoB in Pennsylvania and not NJ. My last guess is that, sometimes, there are state by state rules on what consumers can order or buy themselves. Diagnostic Manufacturers have to do consumer perception studies to ensure that the consumer understands the results they are viewing because they could make health related decisions based on a misunderstanding of the data. A good example is the Owlet device, which is a baby wearable that got pulled from the market because there was a concern parents were misinterpreting the results. That could be it. That’s all I got
