In brief: ?kidney disease
Acute elevation can be due to acute kidney injury, rhabdomyolysis( muscle breakdown), some drugs like trimethoprim may interfere with creatinine excretion and may elevate.
Chronic elevation can be due to chronic kidney disease.

In brief: Renal impairment
Creatinine is a waste product of muscle metabolism that is removed from the blood by the kidneys and eliminated via the urine.
Higher than normal levels indicate reduced ability to clean (clear) the blood, as in kidney disease or increased production of creatinine (as in muscle damage). Low levels are present with good renal function and low muscle mass.

In brief: See below
Creatinine is a blood test, the level helps to calculate GFR glomerular fitration rate, which in turn helps determine level of kidney function.
One can have reduced GFR ie loss of kidney function and still make urine.So the blood test is important.
