Dip-Stick Urinalysis and Methylene Blue (Prosed DS)
|
|
|
| I have FSGS and a chronic/recurring kidney infection and am a
consecutive stone former. Because of these problems, and the similarity
in pain between a stone and flare-up of the infection, I dip my own
samples before calling the doctor.
I was started on Prosed DS* a few weeks ago, which, among other things,
contains methylene blue, which I have found makes *everything* it
touches turn bluegreen. I read a few articles on line which discussed
urinalysis and methylene blue (mostly, that psychadelic urine can be
caused by methylene blue or an infection) and the inserts with the test
reagents (Roche ChemStrip 9 and Bayer MultiStix 10SG) don't list
methylene blue as something that would screw up any of the readings.
Tests done with the methylene blue-tinted samples read as expected (pH
5, pro 4+, everything else normal) except the leukocyte and nitrite pads
are *very* blue. With a positive, they'd turn purple/pink, even with the
methylene blue, right?
I'm asking for future reference, not in lieu of actual medical advice.
Thanks for any information and pointings in the right direction.
*Prosed DS is methenamine 81.6mg, phenyl salicylate 32.6mg, methylene
blue 10.8mg, benzoic acid 9.0mg and hycoscyamine sulfate .12mg

I am not a doctor but suspect that the Prosed DS is altering the results
of the urine dip test. About the only way to determine if it is altering
the results is by testing your urine about an hour before you take the
medication. You should discuss this problem with your doctor during your
next visit just in case you are having high levels of leukocytes which
could be a sign of a Urin. Tract infection.

Jason - Prosed doesn't work that way. At all. Bless your little heart,
but if I don't know the answer, you sure as hell won't.

Urine color is a known interference with dipstick colors. Usually a comment
is attached to such results stating as such. This applies to bright orange
colors as well.
There is no back up test to confirm leukocytes esterase except the actual
microscopic although some automated readers include a blank pad to subtract
urine color attribution from each reaction and thus only report the actual
change in color.
No other way around it sorry.

There is a difference between a suspicion and a statment of fact. You need
to look up the words "suspect" and "suspicion" in your dictionary so that
you will know the difference. I provided a simple test to determine
whether or not
Prosed DS was alterning the results of the dip test. I never stated that
I was certain that Prosed DS was altering the results of the dip test. I
noticed that you deleted the original post.

Thanks for the information! I really did look up a lot of articles and
read all the inserts before asking what is undoubtedly a dumb-XXX
question.
I'm getting a go-to-the-lab result on blood/hemoglobin, so soon I'll
have a real test with which to compare.

Yo. Prosed DS STAYS IN THE SYSTEM BETWEEN DOSES. It's not one pill in
and then it's flushed from the system. You have *no* idea what Prosed DS
is, do you? Hint: it would be ineffective if it worked the way you think
it did.
