Sometimes the cause of hematuria can be elucidated solely on the basis of the medical history and urine testing, or urinalysis. This is especially true for young people, in whom the risk of malignancy is very low.
Best Answer: For a boneless prime rib it averages about 15 minutes per pound at 350F, but it really is best to have a meat thermometer. For medium-rare, you want to take it out of the oven at 135, because it's going to keep cooking a bit, even after it's out of the oven.
The length of time required to cook a prime rib roast depends on the size and doneness. The browning period takes 15 minutes at 450 F followed by slow roasting at 325 F. Total cooking time ranges from 1 1/2 to 4 hours to achieve rare doneness.
