- A microalbumin test checks urine for the presence of a protein called albumin. Albumin is normally found in the blood and filtered by the kidneys. When the kidneys are working properly, albumin is not present in the urine.But when the kidneys are damaged, small amounts of albumin leak into the urine.esults. A microalbumin test checks urine for the presence of a protein called albumin. Microalbuminuria is most often caused by kidney damage from diabetes. The normal values listed here—called a reference range—are just a guide.

- Clinitek® Microalbumin Reagent Strips make it simple and easy to test patients with diabetes. Because testing for microalbuminuria can detect kidney disease in its early stages, physicians may begin intervention earlier than might otherwise have been possible. Clinitek Microalbumin Reagent Strips permit detection of elevated albumin sooner, more sensitively and more specifically than products designed for general protein testing.

- A ratio of albumin (mcg/L) to creatinine (mg/L) of less than 30 is normal; a ratio of 30-300 signifies microalbuminuria and values above 300 are considered as macroalbuminuria. On a standard urine dipstick, 10-20 mg/dL is the minimal detection limit of protein. If the dipstick is positive, then the patient likely has microalbuminuria.

Microalbuminuria For the diagnosis of microalbuminuria, care must be taken when collecting sample for the urine ACR. An early morning sample is preferred. The patient should refrain from heavy exercises 24 hours before the test. A repeat test should be done 3 to 6 months after the first positive test for microalbuminuria.

- The microalbuminuria test is a urine test that measures the amount of albumin in your urine. If kidney damage has occurred, albumin will leak into the bloodstream and will be present in the urine. The microalbuminuria test is also known as: 1  the ACR test.2  the albumin-to-creatinine ratio test. 3  the urine albumin test.hen kidney damage occurs, creatinine levels in the urine decrease while albumin levels may increase. Measuring the amount of albumin in the urine is important for detecting the presence of kidney damage. Kidney damage can lead to kidney failure, requiring the patient to undergo dialysis.

""" I had high micro albumin-creatinine levels in urine. Is this indicative of a problem? """ I had high micro albumin-creatinine levels in urine. Is this indicative of a problem? elevated microalbumin levels (7x from normal cutoff) in urine but normal protein levels (creatinine, albumin etc) in blood. is this indicative of a problem? Answer Elevated microalbumin levels in the urine indicate that your kidneys are leaking protein. There are many conditions that can cause this, and for all of these it is really important to speak to your doctor about this result. The most common causes of elevated protein in the urine is diabetes or high blood pressure (hypertension).

Microalbuminuria Test The purpose of the microalbuminuria test is to measure the amount of albumin in the urine. The test is typically used in conjunction with a creatinine test to provide an albumin-to-creatinine ratio. Creatinine is a waste product in the blood that should be removed by the kidneys.hen kidney damage occurs, creatinine levels in the urine decrease while albumin levels may increase. Measuring the amount of albumin in the urine is important for detecting the presence of kidney damage. Kidney damage can lead to kidney failure, requiring the patient to undergo dialysis.

Microalbumin/Creatinine These levels were gender-specific and noted to be ≥3.9 mg/g cr for men and ≥7.5 mg/g cr for women (1). A persistent microalbumin of >30 mg/g cr indicates a loss in kidney function and is used in the diagnosis of chronic kidney disease (2). (References: 1-Arnlov et al. Circulation 2005; 112:969-975.

ï»¿How is microalbumin:creatinine ratio interpreted? The microalbumin:creatinine ratio is an abbreviated form of a 24-hour urine assay for microalbumin. A simultaneous sampling of serum creatinine and spot urine microalbumin will yield the result. Clinical albuminuria: >300 µg/mg creatinine.

contingent The adjective contingent can be used to describe when something can occur only when something else does first. Making money is contingent on finding a good-paying job. When something is contingent it means that the possibility of an event or situation depends on another happening or being true first. For example, sometimes people want to buy a new house but they make the purchase of the house they want to buy contingent upon someone else buying their old house first.

Being Kind to Your Kidneys: Kidney Function Tests • Albumin-to-creatinine ratio. • Microalbumin-to-creatinine ratio. You may be asked to give a random urine sample or a timed urine sample (such as overnight), or you may be asked to collect your urine over a 24-hour period. (A microalbumin test is not the same as a routine urine dipstick test, by the way).

- Consequently, a high priority in the care of patients with diabetes is screening for early signs of microvascular disease so that measures can be taken to prevent progression to overt complications. For this reason, regular screening for microalbuminuria should be part of routine diabetic preventive care.

Medical Definition of Microalbuminuria Microalbuminuria: 1. Generally, a subtle increase in the urinary excretion of the protein albumin that cannot be detected by a conventional assay. In diabetes, microalbuminuria is an early sign of diabetic kidney disease.2. Specifically, the excretion of greater than 30 mg and less than 300 mg a day of albumin in the urine. The normal urinary albumin is less than 30 mg per 24 hours and 300 mg or more of urinary albumin per day is considered gross albuminuria.enerally, a subtle increase in the urinary excretion of the protein albumin that cannot be detected by a conventional assay.
