Final answer:
Trending upward serum creatinine can be indicative of certain conditions and diseases such as kidney failure and febrile disease. Blood tests such as estimating blood urea nitrogen and plasma creatinine levels can help diagnose kidney problems.
Step-by-step explanation:
Trending upward serum creatinine can be indicative of certain conditions and diseases. One common condition is kidney failure, which can be identified by a low creatinine coefficient. Another potential cause of an increase in serum creatinine is a febrile disease, which can result in a high coefficient. To diagnose kidney problems, blood tests such as estimating blood urea nitrogen and plasma creatinine levels are conducted. These tests assess renal function and help identify abnormalities.
