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 ...
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]
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 ...
Blood Urea Nitrogen (BUN) 8-23 × 10 −5: Bradykinin: 7 × 10 −11: Bromide: 7-10 × 10 −9: Cadmium: normal 1-5 × 10 −9: toxic 0.1-3 × 10 −6: Calciferol (vitamin D 2) Maintain calcium and phosphorus levels 1.7-4.1 × 10 −8: Calcitonin (CT) Hormone <1.0 × 10 −10: Calcium: Bones, Ca 2+ ionized 4.48-4.92 × 10 −5: 4.25-5.25 × 10 ...
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
Soda and juices wreak havoc on blood-sugar levels. Add some interest to seltzer by squeezing in fresh citrus, opting for flavored (but not sweetened) versions, or infusing with a sprig of fresh herbs.
Creatinine levels in μmol/L can be converted to mg/dL by dividing them by 88.4. The 32788 number above is equal to 186×88.4 1.154. A more elaborate version of the MDRD equation also includes serum albumin and blood urea nitrogen (BUN) levels:
Serum creatinine (a blood measurement) is an important indicator of kidney function, because it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys. Creatinine itself is produced [ 5 ] via a biological system involving creatine , phosphocreatine (also known as creatine phosphate), and adenosine ...
