Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles.ellulosic biomass, derived from non-food sources, such as trees and grasses, is also being developed as a feedstock for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions.
1 Even if your bleeding was first discovered through urine testing (urinalysis), you're likely to have another test to see if your urine still contains red blood cells. 2  Urinalysis can also check for urinary tract infection or the presence of minerals that cause kidney stones.
Elevated levels of white blood cells may indicate infection and a low red blood cell count (anemia) may indicate bleeding in the GI tract. Urinalysis can be used to detect red or white blood cells in the urine, which can indicate diverticulitis. Liver function tests may be performed to rule out other conditions. When a definitive diagnosis cannot be made on the basis of physical examination and laboratory tests, imaging tests (e.g., x-rays, computed tomography [CT scan], ultrasound) may be performed.
