Understanding Proteinuria in the Context of Diabetes

Proteinuria in diabetes is not a single entity but a progressive spectrum. In thee arlieste stage, called microalbuminuria, the kidneys leak slall contributs of albumin - between 30 and300 mg per day - into thee urine. This stage is of ten asymptomatic but prepresents a critial window for intervention.

Regulatory andStandardization

Many devices lack regulatory clearance for use in diabetes monitoring. Without FDA or tell agency approval, clinicians are insoctant to rely on results for treatment decisions. Even where clearance exists, different devices may use different units (e.g., mg / g vs. ms. mg / mmol) or reference ranges, complicating data interpretation across care settings.
