Don't think you have to forfeit the soothing feeling of Vaseline if you decide to eschew petroleum jelly, though. If you're looking for a dewy moisturizer, just opt for more natural alternatives and check ingredients. Products containing beeswax, coconut oil, olive oil, shea butter and cocoa butter seal in moisture and don't come with some of the risks of petroleum jelly.
Normal levels. Normal levels of BUN are between 10 to 20 mg/dL for an adult and 5 to 18 mg/dL for a child. Normal creatinine levels are between .5 to 1.1 mg/dL for an adult female and .6 to 1.2 mg/dL for an adult male. Creatinine levels are lower in young children and the elderly as a result of reduced muscle mass.
The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion.A BUN of 15 mg/dl would represent significantly impaired function for a woman in the thirtieth week of gestation.n elevated BUN:Cr due to a low or low-normal creatinine and a BUN within the reference range is unlikely to be of clinical significance. The ratio is predictive of prerenal injury when BUN:Cr exceeds 20 or when urea:Cr exceeds 100.
