Abstract
Polyethylene glycol (PEG plus 14C-PEG) was measured turbidimetrically and by liquid scintillation counting to compare the validities of these methods during the use of PEG as a volume indicator of intestinal perfusion studies in man. Use of 14C-PEG results yielded similar estimates of water absorption or secretion. The simplicity of 14C counting offers practical advantages to the use of 14C-PEG as a nonabsorbable marker for perfusion studies in man.Keywords
