Ova and Parasite Concentrate and Permanent Smear

Patient PreparationInterfering substances-bismuth, barium (wait 7-10 days), antimicrobial agents (wait 2 weeks), gall bladder dye (wait 3 weeks after procedure). Submit 1 of the following specimens following standard collection procedures: Fresh stool added within 30 minutes of collection to a single Total-Fix® vial or 10% formalin transport vial, as well as PVA transport medium. Add stool to bring the liquid level to the "fill to here" line on the vial. Mix well. If parasite infestation is strongly suspected, collect at least 3 stool specimens every other day, since a single specimen can be negative. Un-preserved urine collected at mid-day in a sterile screw-capped container . Peak egg secretion occurs between noon and 3 p. m. Do not submit first morning specimen. In patients with hematuria, eggs may be found trapped in blood and mucous in the terminal portion (last-voided portion) of the urine specimen. Un-preserved bronchoalveolar lavage in a sterile leak-proof container . Deep expectorated sputum, preferably collected in the early morning, in a sterile screw-capped container or in 10% formalin to increase stability.
