 [ Symptoms ] can you tell me what this result means buncreatinine ratio 24 reference range 9 23 [ Disease ] i am happy to help you understand this buncreatinine is a combination of laboratory tests that measure your kidney function bun stands for blood urea nitrogen  the test looks basically looks at your kidneys ability to filter the naturally occurring waste product urea from your blood if you have a high level of urea in your blood then your kidneys may not be working well the creatinine lab test measures how much creatinine another naturally occurring waste product is in your blood the kidneys should filter creatinine very efficiently so a high creatinine level could mean your kidneys are not functioning well the lab result you are asking about buncreatinine ratio basically tells whether or not your are dehydrated when a person is severely dehydrated his or her bun level will rise more than the creatinine level in your case your buncreatinine ratio is 24 that is barely above the high end of the reference range normal range this means you could be mildly dehydrated but basically you seem to be fine wishing you well
