iothalamate

 [i″o-thal´ah-māt]
a water-soluble iodinated radiopaque medium for a variety of radiographic procedures, including angiography, arthrography, urography, cholangiography, and computed tomographic imaging. Available as iothalamate meglumine, iothalamate sodium, or a mixture of the two salts.

Patient preparation and protocols for iothalamate (Conray) administration and subsequent timed blood and urine collections were as described (8).
We calibrated the CE-UV method using 3, 6, 12, 30, and 60 mg/L calibrators prepared using a 600 g/L stock solution of injectable USP grade Conray iothalamate meglumine.
Eight multiple reaction monitoring (MRM) transitions were acquired during this study, with the singly-charged precursor ion of iothalamate at the mass-to-charge ratio (m/z) of 614.
We made controls by adding Conray 60% USP to plasma and urine samples that did not contain iothalamate.
We calculated iothalamate concentration by area under the curve using 1/x weighing with respect to the internal standard and linear regression to extrapolate calibration curves with 32 Karat[TM] software (Beckman Coulter) for CE-UV and Analyst[R] software (Applied Biosystems) for LC-MS/MS.
We calculated the limit of quantification (LOQ) for iothalamate as the response resulting in a CV <20% and recovery of 80%-120% and the limit of detection (LOD) using 3 SDs from the background signal of a zero calibrator.
This overall measure of clinical performance included error components from several sources: measurement of serum creatinine, including specimen nonspecificity effects and the effects on determinants of serum creatinine other than GFR, including generation, secretion, and elimination; and from measurement of GFR as iothalamate clearance, including physiologic differences in renal function and various comorbid conditions.
