Ova + Parasite Exam, Urine

Test ID: 

705841

CPT code:

87177

Synonyms:

Ova and Parasites Examination, Urine

Clinical Use:

Establish the diagnosis of parasitic infection, primarily with Schistosoma haematobium

Test Information:

The diagnosis of Schistosoma haematobium infection is achieved by examination of urine specimens for eggs. Both 24-hour and spot urine samples should be examined to enhance detection. S haematobium egg excretion exhibits a circadium rhythm, with the peak occurring between noon and 3 PM. Egg output is enhanced by physical exercise combined with fluid intake prior to urination. In very light or chronic infections, eggs may be very difficult to detect in urine; consequently, multiple urine sample examinations may be required. Occasionally eggs of S mansoni may also be detected in urine.
