![]() Certain medications, including corticosteroids, azathioprine and tetracycline can result in an elevated BUN that raises your pet’s BUN to Creatinine ratio. Pets with this reason for a high BUN/creatinine number would most likely be anemic as well. Much of that blood is later reabsorbed and the protein in it red blood cells generates more BUN. Those events include bleeding into its intestine or pockets of blood in its body or under its skin subsequent to trauma or surgery. ![]() Perhaps because of a traumatic event such as a car accident or perhaps due to the consumption of a toxic substance.Įvents that cause your pet’s BUN to Creatinine ratio to go up are events that cause your pet’s BUN to increase but cause little or no increase in its creatinine level. However, if the number is markedly elevated, an acute kidney injury might have occurred. When dehydration was the cause of a high reading, your pet’s hematocrit would probably be a bit elevated too. In those cases, and when other laboratory tests and your veterinarian’s physical exam detects no other issues, a second test at a later date should confirm that the first one was a transient event. Why Might My Pet’s BUN:Creatinine Ratio Be High?Ī modestly elevated BUN/Creatinine ratio sometimes just means that your dog or cat was dehydrated when the blood sample was collected. The averages I give in this article are taken from some of my 2022 dog and cat lab reports. (mg/dl = milligrams per deciliter) What is considered the “normal range” varies a bit depending on the laboratory reporting the results or the in-hospital analyzer your veterinarian is using. The normal blood creatinine level for cats is ~0.8-2.0 mg/dl. The normal blood creatinine level for dogs is ~ 0.5-1.6 mg/dl. The normal BUN value for dogs is between ~7-26 mg/dl. The normal BUN to Creatinine ratio for cats ranges from 4 to 33. ![]() The normal BUN to Creatinine ratio for dogs ranges from ~4-27. When one is out of balance with the other, health problems outside your pet’s urinary tract might need to be explored. In those cases, the ratio value should also remain similar over time. The two values should go up or down in tandem when kidney or urinary tract problems are your pet’s underlying issue. Many kidney-related causes can be ruled out or ruled in when BUN is considered in its ratio to your pet’s creatinine level. I mention many of the causes of high BUN level here and creatinine level here. The question is “is it your pet’s kidneys that are the problem or is it something else?” Both BUN and Creatinine are metabolic wastes that your dog or cat needs to clear from its blood through its kidneys and urine. Mathematically calculating the ratio between the amount of BUN/urea and the amount of creatinine in your dog or cat’s blood gives your veterinarian clues as to why your pet’s blood urea nitrogen level (BUN) might be elevated. Update On Kidney Disease Your Dog And Cat’s BUN to Creatinine Ratio = BUN/Cr = BUN:Cr Ratio Your BUN Creatinine ratio test results will typically be available within a few hours after this procedure.Why Is My Dog Or Cat’s BUN:Creatinine Ratio High Or Low? Ron Hines DVM PhDĬauses Of Most Abnormal Blood & Urine Tests A pathologist, a specialist in studying diseases, will collect a small blood sample from your veins using a needle. When your doctor recommends a BUN Creatinine ratio test, you'll likely undergo a simple blood draw specifically targeting the measurement of BUN Creatinine ratio. ![]() Prohibition Park Patteeswaram Blies-Guersviller Heurteauville Inexpressible Island Sector 62, Mohali Bruley Celles-sur-Plaine Lingarajpally Naduvile Jussas Vadakkancheri-II Saint-Cirq, Dordogne Jigni State Kuse, Okayama Rohan, Kharkiv Oblast Toyoura, Hokkaido São José do Vale do Rio Preto Panskura I Sirur Pourrières Neve Zohar Dampierre-au-Temple Rion-des-Landes Shishunaga dynasty Vendières Shopian district Aanakkulam Vazhappally Padinjaru Zœbersdorf Haselbourg Fort Belknap Indian Reservation Malpe Le Theil, Orne West Chicago, Illinois La Chapelle-Vicomtesse Gaoyi, Hebei Chhawla Kingdom of Thessalonica Xinshi Township Gerbéviller Xammes Bonoman Roscoe, Illinois Gaudechart Kurungulam Keelpathi Banaskantha district Bierry-les-Belles-Fontaines ESB Group Isogo-ku, Yokohama This page was viewed the most from these cities in the last 30 days: You might also get this test if your physician BUN Creatinine ratio blood test and the results are not in the normal range (5-15 Ratio), your physician may recommend more tests to figure
