did you get this test done for loose stools? if yes then there may be some element of lactose intolerance
secondary to a diarrheal episode. but this test is not conclusive at all.
the greenish gray coloured stool suggests rapid transit time through the intestine as the colour of stool changes from green to yellow to slightly brownish finally on its transit through intestine, and in this case the rapid bowel movement could have caused this, but this can be an occasionally normal finding in a early infancy.
pH is acidic but it has not mentioned the ph, it may be secondary to some lactose intolerance.
rest other parameters are normal.
at this time best would be to continue breast feeding and according to me its not an indication to shift to lactose free formula, unless the proper history and repeat stool examinations with pH are not available. in any short diarrheal disease this kind of report can be found.
rest you should consult your pediatrician
for further evaluation
hope i ve answered your query
