Yes, I think you may be right that urine will always contain a tiny amount of bacteria.
If you look at the instruction sheet for the urine dipslide test which I uploaded above, it shows various pictures of the bacterial growth spot density on the agar. If the spot density is low, it is considered a negative result. If the spot density is above a certain threshold, then it is considered a positive result.
How Dr Markov determines if a specimen is pathologic? Did he compare to a healthy population?
The urine test of Dr Markov has some red flags:
why exiging warm urine? is there any proof.
Were the thresholds for positivity validated by peers?
Is the Toxicon test validated? reproducible by others?
Some other red flags:
Dr Markov has a business and financial incentive from this theory.
If his theory is true it would have been very easy to convince open minded researchers as Ron Davis. Why trying to convice patients?
An example from MS:
Dr Zamboni proposed Chronic cerebrospinal venous insufficiency as a cause of MS. He proved this by demonstrated abnomalities with an echography probe from a constructor that he had a conflict of interest with.
This probe demonstrated a lot of false positives. Treatement for this condition was ineffective. When scientists did good quality research using gold standard angiography they didn't find a difference between sick and healthy.
I hope that i am wrong but it's too good to be true. The papers of Dr Markov have not one or two but a lot of flaws.
We have to be careful from people taking advantage from our desesperation.
