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.
Blood urea nitrogen-to-creatinine ratio (BUN:creatinine). The BUN test measures the amount of urea in your blood. Urea is a waste product made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine.reatine is broken down into creatinine. Your kidneys take creatinine out of your blood and pass it out of your body in urine. If your kidneys are damaged and can't work as they should, the amount of creatinine in your urine goes down while its level in your blood goes up. Three types of tests can be done.
