Hi,

I have somewhat recently been diagnosed with gastritis.  Doctor did an
upper endoscopy (EGD) and said I had some "spots" in my stomach
that were indicative of gastritis.  Biopsy came back negative for H.
Pylori.  Prior to the EGD I had been on a couple weeks of Prilosec OTC,
now I am on and  have been taking Nexium for a few weeks now as well.
However my symptoms do not seem to be really improving.

Now my doctor wants to do an Esophageal Ph test.  I understand what
this test is and what it measures, however if I have already been
diagnosed with gastritis from the EGD, is this test usual or necessary?
After reading up on it I am not sure how it could help and out of
pocket cost are adding up quickly.  Can GERD cause gastritis, or
gastritis GERD?

Some more background.  A couple years ago I had an EGD, nothing showed
up.  Also had and upper GI, no GERD then either and no mention of GERD
on this latest EGD.  Is a test like this worth the out of pocket cost
in a gastritis case?

Thanks in advance for any answers, help, or ideas someone offers.  It
is much appreciated.
