"filtration level" is a correct and usable phrase in written English.
It is typically used to describe the degree or intensity of filtration, or the quality of the filtering process. Example: The water company has increased the filtration level in response to recent reports of contamination in the local water supply.
The parameters influencing head losses were considered to be eleven parameters representing the filter properties; filtration level, total filtration surface, flow rate, concentration of total sand, filtration time, inside diameter of the inlet and outlet pipes, mean filtration velocity, mean diameter of sand particle size distribution, water viscosity and water density.
If he had been Asian, the glomerular filtration level would have been even lower, but there are no established equations for Asians.
The same patient will have a glomerular filtration level of 66 ml/min if he is Afro-American and 54 ml/min if he is Caucasian, if it is calculated by the MDRD equation.
For instance a 43-year-old 70-kg male patient with a creatinine level of 132 µmol/l has a glomerular filtration level of 63 ml/min if it is calculated by the Cockcroft Gault equation.
This suggests that if follow-up were longer, these participants may have returned to normal filtration levels, albeit this was a small proportion of the total group with follow-up cystatin C-GFR (19 of 243).
While this value increases in older (more than 65 years old) patients admitted to the emergency room [ 10], it dramatically decreases when, in order to screen volunteers, questionnaires for comorbidity, glomerular filtration rate level, ECG, or cardiac imaging were added [ 11].
We were not able to compare endostatin to known cardiovascular risk factors in our study and we were not able, due to missing data, to adjust for pro-brain natriuretic peptide serum levels, estimation of glomerular filtration rate levels or anti-RNA polymerase antibodies.
Because of filtration, nitrate levels on Long Island are currently comfortably within E.P.A. and state limits, but costs could rise if more filtration were needed, according to the water authority.
However, it is unclear whether change in novel filtration marker levels provides additional information for ESRD risk to change in eGFRcr.
In the CLI cohort, patients undergoing LEB were more likely to have glomerular filtration rate levels <30, to have a history of stroke, and to be on dialysis (Table 3).
A recent study by Nyman and colleagues in patients undergoing coronary angioplasty calculated the probability of CI-AKI (SCr rise >0.5 mg/dl (>44.2 μmol/l) or oliguria/anuria) at various estimated glomerular filtration rate levels based on grams of iodine/estimated glomerular filtration rate ratios of 1 2, 1 1, 2 1, and 3 1 [ 11].
