Note that for some parasites the excretion is cyclical and might require several OCP samples e.g. Giardia lamblia. Turn around time 2-3 days. This test is not performed on weekends. Microsporidia infection is associated with chronic diarrhoea in AIDS patients, in the abscence of other enteric pathogens and a low CD4 count. Microsporidiun investigation is not part of the normal OCP investigation, therefore please indicate specifically if clinically indicated. Microsporidium investigations are sent to the London School of Hygiene & Tropical Medicine reference laboratory, turn around time for this test 2 weeks.
Three samples collected on separate days may be necessary to help exclude some parasitic infections
