Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Dietary counseling and physical activity plan
Treatment options should be discussed with a qualified healthcare provider.
Renal function monitoring
Regular assessment of kidney function including serum creatinine, GFR, and urinary markers to monitor progression of renal disease. Early detection of changes allows for timely intervention.
Hematologic malignancy screening
Evaluation for underlying hematologic conditions such as multiple myeloma or lymphoproliferative disorders that can elevate beta-2 microglobulin. Screening should include appropriate imaging and laboratory studies.
Additional treatment options
Renal-protective nutrition
Dietary modifications including appropriate protein intake, phosphorus restriction, and sodium control to protect kidney function. These measures help reduce workload on the kidneys and may improve biomarker levels.
dietaryNephrotoxic medication review
Systematic review of all medications to identify and minimize exposure to nephrotoxic agents. Substitution with safer alternatives when available helps preserve renal function.
medicationDialysis access evaluation
Assessment for dialysis access preparation if renal function decline progresses to end-stage renal disease. Early planning for vascular access improves outcomes when dialysis becomes necessary.
