Final answer:
Blood urea nitrogen (BUN) and creatinine are indicators of kidney function. Elevated BUN levels can indicate kidney failure or febrile disease, while increased creatinine levels are typically detected in cases of renal failure. Blood tests can assess renal function by measuring BUN and creatinine levels.
Step-by-step explanation:
Blood urea nitrogen (BUN) and creatinine levels are indicators of kidney function. Elevated BUN levels can be caused by conditions such as kidney failure or febrile disease, while low BUN levels can be an indication of liver disorders. Increased creatinine levels are typically detected in cases of renal failure. Kidney malfunction can lead to abnormal fluid levels, deranged acid levels, and other complications. Blood tests can be used to assess renal function by measuring BUN and creatinine levels.
