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.
BUN (blood urea nitrogen) is a blood test to check kidney function. So is the serum creatinine test. When your doctor talks about BUN/creatinine levels or a BUN-to-creatinine ratio, he or she is referring to the two main blood tests that tell how well the kidneys are filtering waste products from your blood. The ratio of BUN to creatinine is normally in the range of 10:1 to 20:1.
