History and physical exam don't really point to ARF, they're relatively unspecific and depend on the primary cause, which can range from infection to severe dehydration and cancer.
It's usually after acquiring blood chemistry results that we know something is wrong with kidneys. Azotemia (elevated BUN and Creatnine) is the most important finding, which indicates impaired kidney function. Creatinine is the most important parameter to watch, since BUN can be elevated due to other factors, while elevation of creatnine indicates impaired kidney function.
Besides azotemia, high phosphate, low calcium and high/low potassium are also common findings, while changes of other parameters such as albumin, ALT, AP, AST, glucose... depend on primary cause and present comorbidities.
While it give us indication that something is impairing kidney function, BCP can't give us definitive diagnosis. Combination of history, physical, BCP, urinalysis, CBC and imagining diagnostics as well as their changes in the next few days are required in order to get definitive diagnosis, plus additional specific tests for certain conditions.
