Microalbumin, Random Urine with Creatinine
- (QUEST DIAGNOSTICS)Description:
Measurement of albumin levels in urine below the detection level of urine dipsticks. This test is useful in the management of patients with relatively early diabetes mellitus to assist in avoiding or delaying the onset of diabetic renal disease.
Microalbumin is albumin excreted in the urine and is a sensitive marker of nephropathy. It is used to screen for early renal disease in diabetic patients.
Creatinine is the endproduct of creatine metabolism. Creatine is present primarily in muscle and the amount of creatinine produced is related to total skeletal muscle mass. Daily creatinine production is fairly constant except when there is massive injury to muscle. The kidneys excrete creatinine very efficiently and blood levels and daily urinary excretion of creatinine fluctuates very little in healthy normal people. Since blood and daily urine excretion of creatinine shows minimal fluctuation, creatinine excretion is useful in determining whether 24-hour urine specimens for other analytes (e.g., protein) have been completely and accurately collected.
A significant deviation from the normal range may require further evaluation by your physician.
Includes: Microalbumin, Random Urine with CreatininePatient Instructions:
Exercise within 24 hours, infection, fever, congestive heart failure, marked hyperglycemia, and marked hypertension may elevate urinary albumin excretion over baseline values.
Estimated turnaround for results is 4 business days.
If confirmation testing is required, the estimated time may be extended.
