The implications depend on how much protein and how much blood is in the urine, regardless of race or gender. If there are trace amounts of protein and blood, then there is usually little concern.
If there are high levels of blood and protein in the urine, then a repeat test may be needed to confirm the results. Elevated blood and protein in the urine suggest injury, inflammation, or autoimmune destruction of the kidneys. Injury to the kidneys can be secondary to trauma, hypertension, or diabetes. Inflammatory reactions in the kidney can be secondary to bacterial infections (post-streptococcal glomerulonephritis) or amyloidosis. Lastly, autoimmune diseases such as lupus, IgA nephropathy, or vasculitides.
If you have large amounts of blood and protein in the urine, then you should seek a further evaluation by your primary care physician or a nephrologist.
