By the absence of any literature support, not a single citation even remotely in support, and no reasonable scientific explanation, it can be concluded this practice is far below the standard of care, a total waste of time and money, and draws into question the practice of anyone recommending these tests. Is this an isolated practice or one of many? From my sources sending me copies of the practice, it is not an isolated instance.
Your request for supporting literature was (almost) a thread ender.
I just wanted to comment on the probably appeal of such testing by laypersons.
The collection of an overwhelming number of data points may seem like the best way to arrive at a diagnose and treatment. After all, more information is better, right?
Your advocacy of efficient, specific and scientifically-informed data collection that is careful to avoid waste seems much more practical given the limited financial resources of many patients and the current state of healthcare.
This is true when both approaches arrive at essentially the same diagnosis and treatment but may be even truer when they don't...
However, I thank you for pointing out that this may not necessarily happen given the "cascade effect"; I had not previously considered that the excessive and unnecessary testing, rather than merely satisfying our curiosity of our own physiology, may actually introduce additional risks and potential harm.
Thank you for taking the time to explain these concepts to us!
