Diagnostic approach to glomerular diseases

Abstract

Glomerular diseases are diagnostically complex due to their diverse clinical presentations and underlying etiologies. The diagnostic process begins with a detailed patient history and physical examination, focusing on signs and symptoms indicative of glomerular pathology. Essential laboratory evaluations include urinalysis, emphasizing proteinuria and urinary sediment analysis, and blood tests like serum creatinine and autoimmune markers, which are vital in narrowing differential diagnoses. Imaging modalities, such as renal ultrasound and computed tomography or magnetic resonance imaging scans, where appropriate, contribute additional information regarding renal structure and function. Renal biopsy remains the definitive diagnostic tool, often employed when noninvasive tests suggest significant pathology, guiding diagnosis and treatment strategies. The review advocates for a systematic, multidisciplinary approach to diagnosing and managing glomerular diseases. By elucidating these diagnostic principles, this article improves clinicians’ diagnostic accuracy and patient care in the context of glomerular diseases.
