microalbuminuria

 [mi″kro-al-bu″min-u´re-ah]
an increase in urinary albumin excretion too subtle to be measured by conventional means, often seen with the hyperfiltration of diabetes mellitus.

mi·cro·al·bu·min·u·ri·a

(mī'krō-al-byū'min-yū'rē-ă),
A slight increase in urinary albumin excretion that can be detected using immunoassays but not using conventional urine protein measurements; an early marker for renal disease in patients with diabetes.

microalbuminuria

/mi·cro·al·bu·min·uria/ (-al-bu-min-u´re-ah) a very small increase in urinary albumin.

microalbuminuria

[mī′krō·al′bo̅o̅minoo͡r′ē·ə]
the urinary excretion of small amounts of albumin, below the detection level of routine dipstick analysis. The condition is an early indicator of altered glomerular permeability in diabetes.

microalbuminuria

The excretion of 30–300 mg albumin/day. An increase in albumin excretion predicts haemodynamic and morphologic changes of diabetic nephropathy. When increased, it is an early indicator of renal failure; the risk of microalbuminuria in diabetics increases when HbA1 value rises > 10%. Microalbuminuria is not invariably associated with renal failure and, in some patients, may regress.

microalbuminuria

Nephrology The excretion of 30-300 mg albumin/day; ↑ albumin excretion predicts hemodynamic and morphologic changes of diabetic nephropathy; when ↑, is an early indicator of renal failure the risk of microalbuminuria in DM ↑ when HbA1 value rises > 10%. See Diabetic nephropathy.

A slight increase in urinary albumin excretion that can be detected using immunoassays but not by means of conventional urineprotein measurements; an early marker for renal disease in patients with diabetes.

microalbuminuria

The presence of almost undetectable traces of the protein albumin in the urine.

microalbuminuria

persistent excretion of small amounts of protein (<500mg in 24 hours) in urine due to incipient nephropathy; earliest presentation of kidney failure of diabetic nephropathy

A slight increase in urinary albumin excretion that can be detected using immunoassays but not by means of conventional urine protein measurements; an early marker for renal disease in patients with diabetes.

microalbuminuria

(mī´krōalbyoo´mənur´ēə),
n a type of albuminaria that is characterized by relatively low levels of albumin in the urine (between 30 and 300 mg in 1 day). The increase in albumin secretion is generally too small to be detected by a conventional dipstick test but can indicate the beginnings of kidney disorders, especially those related to diabetes.

Microalbuminuria was defined as a UACR [greater than or equal to] 25 mg/g in women and 17 mg/g in men (25).
Following hyperfiltration microalbuminuria and proteinuria develop (8.
Microalbuminuria is defined as 30-300 mg/d in a 24-h collection or 30-300 mg/mg creatinine in a spot collection
7) The preferred method for screening for microalbuminuria is to measure the ACR in a random spot urine sample.
14) However, in a much larger study of 1 000 patients with DM and persistent microalbuminuria, the sulodexide microalbuminuria trial (SUN-Micro-Trial), there was failure to achieve the primary endpoint of reduction in urine albumin excretion.
Moreover, acute exercise-induced microalbuminuria has been used as a provocative test for the early detection of diabetic nephropathy in patients without microalbuminuria (Felt-Ramussen, 1985; O'Brien et al, 1995).
They could not find any relationship between retinopathy and disease duration, however, they found that presence of microalbuminuria was related with disease duration and retinopathy.
The earliest clinical sign of nephropathy is the detection of albumin in the urine (> 30 mg/day but <300 mg/day); this is the microalbuminuria stage.
The method may adavnatageously be applied for early detection of kidney damage, in particular when the subject does not yet show any sign of microalbuminuria.
Microalbuminuria is used to describe albumin concentrations in the urine that are greater than normal but not detectable with a common urine dipstick assays.
