2. Urea-to-creatinine ratio - Wikipedia

   en.wikipedia.org/wiki/Urea-to-creatinine_ratio

   In medicine, the urea-to-creatinine ratio (UCR [1]), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea is just over twice BUN (60/28 ...

3. Azotemia - Wikipedia

   en.wikipedia.org/wiki/Azotemia

   Measurements of urea and creatinine (Cr) in the blood are used to assess renal function. For historical reasons, the lab test measuring urea is known as "blood urea nitrogen" (BUN) in the US. The BUN:Cr ratio is a useful measure in determining the type of azotemia and will be discussed in each section below. A normal BUN:Cr is equal to 15. [3]

   BUN is an indication of kidney health. The normal range is 2.1–7.1 mmol/L or 6–20 mg/dL. [1]The main causes of an increase in BUN are: high-protein diet, decrease in glomerular filtration rate (GFR) (suggestive of kidney failure), decrease in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, [5] fever, rapid cell destruction from infections, athletic ...

   Creatinine: Male: 60, [5] 68 [174] 90, [5] 118 [174] μmol/L: May be complemented with creatinine clearance: 0.7, [175] 0.8 [175] 1.0, [175] 1.3 [175] mg/dL Female: 50, [5] 68 [174] 90, [5] 98 [174] μmol/L 0.6, [175] 0.8 [175] 1.0, [175] 1.1 [175] mg/dL BUN/Creatinine Ratio: 5 [23] 35 [23] – Plasma glucose (fasting) 3.8, [14] 4.0 [5] 6.0, [5 ...

6. Assessment of kidney function - Wikipedia

   en.wikipedia.org/wiki/Assessment_of_kidney_function

   Creatinine clearance exceeds GFR due to creatinine secretion, [4] which can be blocked by cimetidine. Both GFR and C Cr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result ( eGFR and eC Cr ) The results of these tests are used to assess the ...

7. Basic metabolic panel - Wikipedia

   en.wikipedia.org/wiki/Basic_metabolic_panel

   Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...
