Abstract
An object of the present invention is to provide a method capable of detecting whether a subject has systemic lupus erythematosus (preferably nephrotic syndrome) with high accuracy without performing a renal biopsy, a biomarker for carrying out such detection, and the like. The concentration of 3',4′-didehydro-3′-deoxycytidine in urine collected from a test subject is measured, and this concentration is compared with a reference concentration for control, which allows to detect whether the above-mentioned test subject has systemic lupus erythematosus (preferably lupus nephritis) with high accuracy.
