Elevated Urinary Guanosine Level C5936794
An elevated level of guanosine, a component of genetic material, in urine. This may suggest issues with how the body processes purines. Further metabolic testing is typically needed to determine the cause.

Initial screening tests
Standard diagnostic workup
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
Allopurinol Therapy
Xanthine oxidase inhibitor to reduce purine degradation and lower guanosine and uric acid accumulation in disorders of purine metabolism such as Lesch-Nyhan syndrome.
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Purine-Restricted Diet
Low-purine dietary approach eliminating organ meats, certain seafood, and alcohol to decrease substrate load for guanosine and uric acid production.
Additional treatment options
Febuxostat Alternative
Non-purine xanthine oxidase inhibitor for patients intolerant of allopurinol, providing similar reduction in uric acid production and guanosine metabolite accumulation.
medicationBehavioral Management Program
Comprehensive behavioral interventions including positive reinforcement, environmental modifications, and protective measures for patients with self-injurious behaviors associated with purine disorders.
psychologicalUric Acid Nephrolithiasis Intervention
Surgical or procedural management of kidney stones caused by elevated uric acid and guanosine metabolites, including stone removal or dissolution therapy.
