The clinical test erythrocytes (red blood cells) acquired from a patient's urine is a test used to detect the presence of blood in the urine. This test is usually performed as part of a routine urinalysis. The test is performed by collecting a sample of the patient's urine and then examining it under a microscope for the presence of red blood cells. The sample can be collected in a clean, dry container and then sent to a laboratory for analysis. The laboratory will then use a microscope to look for the presence of red blood cells in the sample. If the sample contains red blood cells, then the test is considered positive and further testing may be necessary to determine the cause of the bleeding.
