Which urinary sediment element is a granular cast typically seen with protein positivity?

The main idea here is that the appearance of casts in urine reflects what’s happening in the tubules, especially when proteins are involved. Granular casts form when material inside a tubular cast breaks down or when granular protein aggregates are present, so they’re commonly seen when there’s protein in the urine. If the urinalysis also shows protein positivity, that supports a scenario where these granular casts are associated with protein leakage or tubular injury. Hyaline casts are clear and non-granular and can appear with dehydration or diuretics, not specifically tied to protein positivity. Ova are parasitic eggs, not casts. Mucous is not a cast. So granular casts with positive protein best match the described sediment element.
