Creatnine levels, not sure what it means.?My aunt has Polycystic Kidney Disease. She got a kidney transplant about 10 years ago and the past year has been having trouble. Her recent levels was 3.2. What does that mean? Thanks

A combination of blood and urine creatinine levels may be used to calculate a creatinine clearance. This measures how effectively your kidneys are filtering small molecules like creatinine out of your blood. Urine creatinine may also be used with a variety of other urine tests as a sort of correction factor. Since it is produced and removed at a relatively constant rate, the amount of urine creatinine can be compared to the amount of the other substance (such as protein) being measured.
Serum creatinine measurements (along with your age, weight, and gender) also are used to calculate the estimated glomerular filtration rate (EGFR), which is used as a screening test to look for evidence of kidney damage.
When is it ordered?
Creatinine may be ordered routinely as part of a comprehensive or basic metabolic panel, when someone has non-specific health complaints, is acutely ill, and/or when a doctor suspects kidney dysfunction. The creatinine blood test may be ordered, along with the BUN test, at regular intervals when the patient has a known kidney disorder or has a disease that may affect kidney function or be exacerbated by dysfunction. Both may be ordered when a CT scan is planned, prior to and during certain drug therapies, and before and after dialysis to monitor the effectiveness of treatments.
Increased creatinine levels in the blood suggest diseases or conditions that affect kidney function. These can include:
damage to or swelling of blood vessels in the kidneys (glomerulonephritis) caused by, for example, infection or autoimmune diseases;
bacterial infection of the kidneys (pyelonephritis);
death of cells in the kidneys' small tubes (acute tubular necrosis) caused, for example, by drugs or toxins;
prostate disease, kidney stone, or other causes of urinary tract obstruction; or
reduced blood flow to the kidney due to shock, dehydration, congestive heart failure, atherosclerosis, or complications of diabetes.
Creatinine can also increase temporarily as a result of muscle injury.
