What does it mean if you:

. have a history of high blood pressure
. you're told by your doctor that you can't eat red meat for the rest of your life or kidneys will get worse.
First, are you male or female?
If you are female, it may be as simple as having blood cells from the vagina being washed into the specimen when you collected it.
Any urine specimen should be collected using the "clean catch" technique: http://www.saintfrancislab.com/documents/pated/Collecting%20a%20Clean%20Catch%20Urine%20Specimen. pdf (broken link).
Many labs will not suggest doing this unless it is planned to culture the urine for bacteria, but vaginal secretions mixed with urine can cause the specimen to test positive for blood and protein and normal skin and vaginal bacteria can make the urine look infected when it is not. Ladies, do not just pee in the cup; do a clean catch every time!
Ideally, women should give a specimen about two weeks after a menstrual period.
If you are male, just because of the obvious difference in a anatomy, contamination of the urine is less likely.
Exercise can cause blood in the urine, so it is best to collect the specimen about 48 hours after a vigorous workout.
Next, how was the blood discovered? If it was only a chemical test (done with a little paper strip), was the specimen also tested by looking at a drop under the microscope to look for red blood cells? If so, how many red cells are present? Normal people may have a few. If there are a significant number of red cells present, it is reasonable to repeat the urinalysis at least once and maybe twice before doing any further testing.
If there are any symptoms of an infection or the clean catch specimen contains bacteria, the infection should be treated and the urinalysis repeated after the antibiotic is finished. Ideally, a culture should be obtained to determine exactly what bacteria is causing the infection. Infection is the most common cause of blood in the urine.
In men, enlargement of the prostate or urethral infections can be a cause.
People with kidney stones frequently have other symptoms, including flank pain.
The older you are, the greater the risk of more serious problems, including tumors.
Your doctor would want to do additional testing to rule these out. These can include looking at the urine for abnormal cells, imaging studies of the kidneys and bladder, or cystoscopy, in which a telescope is inserted into the bladder through the urethra to visualize the lining of the bladder.
Yes, uncontrolled high blood pressure is the most common cause of chronic kidney failure. However, the earliest symptom of this is usually tiny amounts of protein --- albumin --- in the urine, not red cells. If your blood pressure has been well controlled and blood tests of kidney function are normal, the blood in the urine is most likely not caused by high blood pressure.
I am puzzled that a low protein diet would be recommended before a diagnosis of the cause of the blood in the urine has been determined. Unless there is chronic kidney disease present, I fail to see a basis for restricting protein. If it is necessary to limit protein intake, it would be from all sources, not just red meat. Eating protein will not damage healthy kidneys, though many of us eat way more protein than we really need.
I agree with the other posters. You need more information from your doctor. Telling you that you have blood in your urine and need to stop eating red meat is not acceptable.
