Which element reflects the presence of ova in urine?

Finding ova in urine indicates a parasitic infection that sheds eggs into the urinary tract, most classically urinary schistosomiasis caused by Schistosoma haematobium. The eggs are actual parasite reproductive units and their presence directly signals a helminth infection identified by urine microscopy. Other items reflect different things: mucus in urine can come from irritation or contamination and isn’t evidence of parasite eggs; RBC casts are formed in the kidney and point to renal disease rather than a parasitic infection; starch contamination is an artifact that can appear in samples but does not reveal eggs of parasites.
