The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. Posted by dkwinter. jsmodule_ureammoll=jsmodule_ureamgdl*0.3571; Blood urea nitrogen to creatinine ratio is associated with congestion and mortality in heart failure patients with renal dysfunction. See below for information on factors affecting results. ... P-values were calculated by Mann–Whitney U-test, t-test or χ 2 test, as appropriate. Acute kidney injury (AKI) occurs commonly in hospitalized patients and carries a high mortality [1–3]. This also depends upon the protein intake. if (isNumeric(jsmodule_ureammoll)) { 1 Definition; 2 Indikationen; 3 Referenzbereich; 4 Interpretation; 5 Umrechnung BUN-Harnstoff. Harnstoff-Stickstoff ist ein Laborparameter, der im Serum bestimmt wird. A total of 21/52 (30%) of the elderly subjects had a GFR >70 ml/min/1.73 m2, but none of these persons was aged >90 years. var siRatio=Math.round(100*jsmodule_ureammoll/jsmodule_creatininemgdl)/100; 2. } 1. The information contained in this video is not a substitute for medical advice. A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys and liver are working. var jsmodule_ureamgdl=document.getElementById('jsmodule_ureamgdl').value; BUN to creatinine ratio specifies the ratio of two serum laboratory values, the blood urea nitrogen and serum creatinine,this ratio is used to evaluate the cause of acute kidney damage. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion. The determination of serum blood urea nitrogen currently is the most widely used screening test for the evaluation of kidney function. Der Harnstoff eignet sich daher nicht zur Diagnose einer verminderten Nierenfunktion. Given, Blood urea nitrogen= 4 mg/dL Serum creatinine = 2 mg/dL. Very useful for US-trained physicians who want to calculate the familiar BUN/Cr ratio but using SI inputs. Ursachen liegen in der Niere (Renale Azotämie) Die verschiedensten Nierenerkrankungen können eine Erhöhung des Harnstoffs bewirken. Individual laboratories will have different reference ranges as the assay used can vary between laboratories. Blood urea nitrogen= 4 mg/dL Serum creatinine = 2 mg/dL, BUN:Cr = Blood urea nitrogen / Serum creatinine = 4/2 = 2 : 1, Your email address will not be published. Blood urea nitrogen and serum creatinine: not married in heart failure. c. Data were missing for some patients for ‘Signs and symptoms’ and ‘Treatments’. Urea and urine concentrating ability: new insights from studies in mice. The BUN, then, is roughly one-half (7/15 or 0.466) of the blood urea. Content on this page has not been checked for accuracy. var jsmodule_creatinineumoll=document.getElementById('jsmodule_creatinineumoll').value; A blood urea nitrogen (BUN) test measures the amount of urea nitrogen that’s in your blood. Code to add this calci to your website Just copy and paste the below code to your webpage where you want to display this calculator. Urea is formed in and released by the liver into the blood and is carried to the kidneys, where it is filtered out of the blood and released into the urine. 4. function isNumeric(n) { The results for the blood urea nitrogen test is measured in mg/dL, which is referred to as milligrams per deciliter. Serum creatinine is the true assessment tool of renal function. 3.2. document.getElementById('jsmodule_creatininemgdl').value=Math.round(jsmodule_creatininemgdl); } So the UN results (mg/dL) are calculated from the machine provided urea results (mg/dL) as follows: UN = urea x 0.467 in unit equivalent (mg/dL). 2.
