It's less expensive to refinish the bathtub ($300-$600) or install a bathtub liner ($500-$4,000), but a replacement can mean you get precisely the tub you want.eplacing a fiberglass one with an acrylic whirlpool one. The estimate I got was for $3900.00 with me buying the tub and with a notice that the costs could go up if they have difficulty setting the tub. The tub cost $800. I am trying to keep costs down, so I am having them minimize the tile replacement.
The BUN-to-creatinine ratio is not a precise or reliable test, though. It may often be somewhat abnormal in healthy people. More important is the creatinine level itself; if itâs elevated, the kidneys are not working properly, and the reason should be sought out.
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.
