Although radiologic confirmation of tube placement remains the "gold standard," there is growing evidence that pH testing of feeding-tube aspirates can reduce (although not totally eliminate) reliance on x-rays used for this purpose. This article describes that evidence and tells how it was obtained. Reducing the number of x-rays needed to confirm tube position can have far-reaching financial benefits.
