Guest guest Posted February 23, 2005 Report Share Posted February 23, 2005 Hi, folks, I'm having a blood draw tomorrow and I'd like to know which is the better, more informative test for catecholamines: catecholamines, urine fract -- OR metanephrines, fract I'll be marking this one myself, but the doc's office told me to 'mark whatever I wanted'. Ohhh, the power! LOL Cheers, Friday Quote Link to comment Share on other sites More sharing options...
