Quoted message said:Did I make up the following statement or do you think that I found the
statement in a book that was written by a team of three medical doctors:
"Urine pH is crude indicator of the acid-base balance of the body...
Too crude to be used routinely in most cases. A urinalysis is done in order
to check for ketones (ketoacidosis), glucose (fanconi syndrome), protein
(tubular or glomerular proteinuria ) and infection.
Quoted message said:When an accurate pH assessment of acid-base status and renal response
The renal response means that one can have renal tubular acidosis being the
origins of the metabolic acidosis associated with bicarbonate wasting in the
urine rendering the urine more alkaline than usual and not more acidic than
usual. The urine pH may be misleading. This type of acidosis is the opposite
in pH compared to what it should be in urine. The only way to tell is by
doing a blood gas ABG to determine acidosis or alkalosis. The blood CO2's
relationship to the pH is important in determining mixed acid-base conditons
such as metabolic acidosis combined with respiratory alkalosis.
Quoted message said:is desired, the urine should be collected under circumstances more
controlled than usual... ...Simultaneous serum pH mahy also be
ordered..."
The circumstances refer to collection anaerobically meaning in a syringe and
placed on ice or in urine in a cup with an oil overlay to protect from air
after bicarb loading the patient to correct the acidosis. Urine CO2 are
also performed and I have seen this about once every five years or so. To
say that it is routinely done or implied is way off.
Urine pH's are monitored in some intensive care situations involving some
therapeutic interventions which are more commonly performed but again this
occurs a handful of times a month.
The book, like the one concerning "eat right for your blood type" is based
on sound medical science but both take the interpretation off to space once
you leave the basic medical science.
It's sort of like telling people not to breath oxygen because oxygen is
involved in the origins of oxidative damage.
