Additional 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.
