Investigation of apparent non-albuminuric proteinuria in a primary care population.

Background: There is debate as to whether using the urinary albumin- or protein-to-creatinine ratio (ACR or PCR) should be the primary test for proteinuria. Whilst albuminuria (increased ACR) in the absence of proteinuria (increased PCR) may be expected in some patients, the converse (i.e.

The diagnostic accuracy of a urine albumin-creatinine ratio point-of-care test for detection of albuminuria in primary care.

Background: Albuminuria is an important sign of chronic kidney disease and is detected routinely by measurement of urinary albumin-creatinine ratio (ACR). A Siemens CLINITEK test designed for use at the point of care is available that can semiquantitatively measure ACR.

Study Design: Diagnostic accuracy study evaluating a urinary ACR point-of-care test.
