Urinary analysis is one of the most requested tests in the clinical laboratory. This test includes the physical, chemical and microscopic analysis of urine. This last one allows for the observation of urinary sediment (US) in search of formed elements (cellular cast, leukocytes, etc.), with different diagnostic uses. Urinary analysis can be assessed by manual or automated methods. In the laboratory diagnosis of autoimmune diseases, US analysis is mainly oriented towards the assessment of renal function in patients with lupus nephritis (LN) as this is a common clinical manifestation associated to systemic lupus erythematosus (SLE). Additionally, its value lies mainly for diagnostic criteria and evaluation of kidney injury, as well as for several damage indexes directed to patients with SLE. In the last years, several groups have sought to establish new urinary biomarkers of kidney damage in patients with SLE; however, this requires a greater number of studies to determine their true diagnostic value in this patients group.
