Embodiment Construction

[0029] figure 1 A method 100 is depicted for determining or approximating a patient's glomerular filtration rate (GFR) or a patient's creatinine clearance.

[0030] Method 100 includes a step 101 of determining a patient's serum creatinine concentration, which in one embodiment is preceded by or includes a step 111 of measuring the serum creatinine concentration on a blood sample previously taken from the patient. Alternatively, the serum creatinine concentration is manually entered into the user interface of the system 300 .

[0031] Method 100 further includes a step 102 of determining the patient's lean tissue mass. In one embodiment, step 102 is preceded by or includes a step 112 of measuring lean tissue mass by applying bioimpedance measurements.

[0032]The method 100 also includes a step 103 of determining the patient's GFR or the patient's creatinine clearance based on the patient's serum creatinine concentration determined in step 101 and based on the patient's lean...

Abstract

A method and an apparatus for determining or approximating a patient's glomerular filtration rate or a patient's creatinine clearance are disclosed. The method comprises the following steps: determining a serum creatinine concentration of the patient, determining a lean tissue mass of the patient, and determining the glomerular filtration rate of the patient or the creatinine clearance of the patient based on the serum creatinine concentration of the patient and the lean tissue mass of the patient.

Description

technical field [0001] The present disclosure relates to methods for determining a patient's filtration rate, in particular a patient's glomerular filtration rate or equivalent creatinine clearance. It further relates to corresponding devices and to diuretics. Finally, the disclosure relates to computer program products and computer programs. Background technique [0002] The measurement of GFR (Glomerular Filtration Rate) is a commonly used method to assess kidney function in daily clinical practice. The management of patients with chronic kidney disease or declining renal function is largely determined by GFR, and thus, the stages of chronic kidney disease (CKD stages) 1-5 have been defined based on GFR. GFR (Glomerular Filtration Rate) is an important clinical parameter used to assess kidney function. Most so-called bedside methods (ie, methods used in clinical practice to determine GFR) are based on the measurement of creatinine (so-called serum creatinine) from blood...
