iGFR), as described above, also denoted as mGFR (measured GFR). Iohexol plasma clearance for measuring glomerular ﬁltration rate in clinical practice and research: a review. Part 1: How to measure glomerular ﬁltration rate with iohexol? Pierre Delanaye1, Natalie Ebert2, Toralf Melsom3,4, Flavio Gaspari5, Christophe Mariat6, Etienne Cavalier7, Jonas Björk8, Anders Christensson9, Accuracy of 7 different formulas for calculating measured GFR (mGFR) based on iohexol clearance measurements (see Table 1 for the formulas and the Introduction for more details). GFR (mL/min/1.73 m 2 ) was calculated by 2-point GFR (GFR2p) using the different formulas as indicated and with blood sampling at 2 and 5 h after injection. Jump to Content Jump to Main Navigation Jump to Main Navigation Patienten får ej ha genomgått röntgenundersökning med jodhaltigt kontrastmedel 4 dygn före iohexol-undersökningen eller vara överkänslig mot jodhaltiga kontrastmedel. I det senare fallet rekommenderas krom51-EDTA clearance på Bild- och funktionsanalys i Malmö eller Klinisk fysiologi i Kristianstad.

2018 Apr;33(4):683-696. doi: 10.1007/s00467-017-3841-y. METHODS: The GFR of 96 children with different stages of chronic kidney disease (CKD) (median age 9.2 years, range 3 months to 17.5 years) was determined using the iohexol plasma clearance, with blood sampling at seven time points within 5 h (GFR7p) as the reference method. Median GFR7p was 65.9 (range 6.3-153) mL/min/1.73 m2. GFR BM =0.990778× Cl 1 −0.001218× Cl 12, where Cl 1 is the plasma clearance calculated according to the one-compartment model. One-compartment plasma clearance of iohexol can be determined by using different sampling protocols in the slow compartment phase. Results: Mean ± SD iohexol clearance estimated via multisample and corrected slope-intercept methods was 2.16 ± 0.35 mL/min/kg and 2.14 ± 0.34 mL/min/kg, respectively.

80 Iohexol clearance ( EMA recommendation 2004) Iohexol clearance and four other GFR methods. 2020年10月19日 This study reports on performance comparisons between various mathematical formulas proposed for iohexol plasma clearance vs. inulin urinary The new iohexol assay from deltaDOT/RVC provides a highly accurate measure of glomerular filtration rate. Because GFR is directly correlated with functional GFR was measured (mGFR) as plasma clearance of iohexol using a single plasma sample technique, which is considered as reliable as using multisampling [21]. enzymatic plasma creatinine, 24-h creatinine clearance, GFR estimated from plasma creatinine by the Cockcroft-Gault equation, and iohexol clearance as a gold Abstract: Plasma clearance of iohexol was evaluated in eight anesthetized California sea lions (Zalophus correction formula was necessarily developed.
