Clinical measurement of renal clearance
Current Opinion in Nephrology and Hypertension, 1992The importance of renal clearance in uronephrology has motivated the continuous reassessment of well-established methods and the relentless search for better techniques. Concerning radionuclide methods, data in the current literature confirm the validity of the simplified one-compartment model or the empirical single-sample method for renal clearance ...

Hepatic Clearance Measurements and Pharmacokinetics
Pharmacology, 1979This review emphasizes the need for well-defined models for hepatic pharmacokinetics and discusses the interpretation of hepatic clearance measurements. Such recent approaches are subjected to theoretical and experimental comparisons. The pharmacokinetic consequences, including a classification of drugs according to hepatic clearance, are outlined.

Derivation of uncertainty propagation for clearance measurement
Applied Radiation and Isotopes, 2021Clearance measurements are performed to calculate the sum of the ratios of the measured activity concentration to the limit for all nuclides to be considered. In the derivation of the uncertainty, the modeling of the measurement is essential. By using formula for the modeling, the uncertainty and upper limits of the coverage interval can be calculated ...

Automatic, Noninvasive Intradialytic Clearance Measurement
The International Journal of Artificial Organs, 1993The feasibility of non invasive, automatic intradialytic measurement of effective clearance is demonstrated by a mathematical derivation. In a practical setting the conductivity difference between dialysate inlet and outlet of the dialyzer is measured for two different dialysate inlet concentrations.

Comparison of creatinine clearance estimates with routine measured clearance
Clinical Biochemistry, 2007Compare GFR estimates (eGFR) calculated by formulas (CG, CGI, MDRD) and creatinine clearance (CrCl), in subgroups based on sex, age, BMI and serum creatinine (Cr).eGFR is calculated with Cockgroft-Gault (CG), CG corrected for ideal or lean weight (CGI), and Modification of Diet in Renal Disease (MDRD) formulas using a compensated kinetic Jaffé method ...

Pitfalls of In Vivo Dialyzer Clearance Measurement
Advances in Renal Replacement Therapy, 1995Dialyzer small-molecule clearance measurements are commonly made to help identify the cause of inadequate dialysis prescriptions, to determine the efficacy of reuse procedures, or to choose between different types of dialyzers. Clearance measurements can be blood-side- or dialysate-side-based.

Deposition of aerosols and bronchial clearance measurements
European Journal of Nuclear Medicine, 1987A special inhalative device is described for reproducible deposition patterns of radioactive aerosols to measure mucociliary and tussive clearance and to evaluate the effect of drugs on the bronchial tree. Additive actions on mucus transport exist between beta 2-agonists and theophylline, but not in combination with inhalative quaternary ammonium ...

Measured Creatinine Clearance (MCC)
1989Renal creatinine clearance is a frequently used measure of renal function. The creatinine clearance is the rate at which creatinine-containing serum is cleared of creatinine; a low creatinine clearance corresponds to diminished renal function. To measure renal creatinine clearance, a 24-hour urine collection is generally taken and the serum creatinine ...

Measurement of Apoptotic Cell Clearance In Vitro
2004The phagocytic clearance of apoptotic cells is a highly efficient and nonphlogistic process in vivo. Research in this area has been limited, at least in part, by technical difficulties associated with the techniques used in the detailed study of apoptotic cell clearance mechanisms.

Measurement of back clearance.
ASAIO transactions, 1991With improvement in dialysis membranes, back filtration becomes the focus of study. Because new membranes that remove low molecular weight proteins, such as beta 2-microglobulin by diffusion are now available for clinical use, both back filtration and back diffusion become problems.
