The presentation of all types glomerulonephritis are the same. If a patient is suspected to have DPGN, a blood and urine test will be done first. A urine test will be done to determine if there is protein or blood in the urine. A blood test will be to measure the levels of creatine in the blood. An ultrasound will be done to see if there is inflammation of the kidneys and to look for blockages. A kidney biopsy is the most important diagnostic tool. With a biopsy, the sample will be looked at histologically. With this information, a proper diagnosis can be completed. There are many forms of glomerulonephritis, but under a microscope, DPGN will show increased cell count of polymorphonuclear cells, cellular crescents, and fibrinoid necrosis. A patient with DPGN will have more than 50% of their glomeruli involved. If a patient has DPGN, that means they have an active form of glomerulonephritis.
