Today, Intel is adding 14 new processors under its Core i3, i5, and i7 designations while also expanding its Pentium and Celeron ranges with new models as well. This is the first time in the company's history that it's refreshing every segment of its consumer CPU lineup at the same time.
The normal ratio of BUN to creatinine in the blood is between 10 and 20 to 1, more or less, although this normal range varies with age and gender. Ratios higher than 20 to 1 or lower than 10 to 1 (with the above caveat) are both indicative of certain kidney problems.
The BUN/Creatinine ratio is useful in the differential diagnosis of acute or chronic renal disease. Reduced renal perfusion, e.g., congestive heart failure, or recent onset of urinary tract obstruction will result in an increase in BUN/Creatinine ratio. Increased urea formation also results in an increase in the ratio, e.g., gastrointestinal bleeding, trauma, etc. When there is decreased formation of urea as seen in liver disease, there is a decrease in the BUN/Creatinine ratio. In most cases of chronic renal disease the ratio remains relatively normal.
