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.
What Are BUN and Creatinine? BUN stands for blood urea nitrogen. The BUN is a measurement that represents the level of urea in the blood. Urea is considered one of the bodyâs waste products. It is produced when the liver participates in protein metabolism, and it is usually eliminated from the body by the kidneys.
