Sean, I asked two of my colleages who are familiar with Abbott Dig III. One replied to you yesterday - off list. The other says: "From what I can tell, it is 50% higher with the same reference range. Moreover, most clinicians now use a range of 0.8 - 1, rather than the classical 1-2. We looked at this Abbott test and immediately switched to the Vitros." -Jim ------ACB discussion List Information-------- This is an open discussion list for the academic and clinical community working in clinical biochemistry.
