Therefore, abnormal BUN-to-creatinine ratios can be an early indicator of kidney dysfunction and alert healthcare professionals to take preventive measures. On the other hand, a BUN-to-creatinine ratio low may indicate inadequate hepatic urea synthesis or a low-protein diet. If the BUN/creatinine ratio is high, it may suggest a problem with the kidneys' ability to function correctly, a condition called renal impairment. Typically, the ratio is between 10:1 and 20:1, with a slightly higher ratio in older adults. The ratio of BUN/creatinine is an indicator of kidney health. Therefore, BUN and creatinine are useful markers in assessing kidney health because they help doctors evaluate the kidneys' filtration rate. The kidneys filter creatinine from the blood, and its levels in the body reflect the efficiency of the kidney's excretory function. Creatinine is a waste product created by the breakdown of phosphocreatine, a molecule stored in muscle tissue. The kidneys then filter it out of the blood and eliminate it through urine. What is bun creatinine ratio?īlood urea nitrogen (BUN) is a waste product produced when the liver breaks down protein.

This blog post will explore the importance of the BUN-to-creatinine ratio and what it means for your kidney function.

One way to assess kidney function is by looking at the BUN-to-creatinine ratio, a critical marker for kidney health. Therefore, monitoring kidney function is essential. When the kidneys fail to function correctly, it can lead to severe complications affecting a person's overall health. Kidneys are essential organs that filter waste products from the blood, regulate electrolyte balance and blood pressure, and produce hormones that control red blood cell production.
