Elevation of kidney tests in lupus indicates inflammation targeting which organ?

Explanation:
In lupus, elevation of kidney tests signals inflammation targeting the kidneys, known as lupus nephritis. Immune complexes form and deposit in the glomeruli, triggering an inflammatory response that damages the kidney’s filtering units. This impairment raises wastes in the blood (higher BUN and creatinine) and often shows up in the urine as proteinuria and sometimes hematuria with red blood cell casts. While lupus can involve other organs such as the liver, heart, or lungs, a rise in kidney-specific labs points to renal involvement. Recognizing lupus nephritis is crucial because it guides treatment toward immunosuppressive therapy and careful monitoring of kidney function.
