TEST ID OP OVA AND PARASITES, STOOL

Important Note

Norman Regional Laboratory Services will no longer perform Ova and Parasite testing in-house due to low volumes and low prevalence. 

Norman Regional Laboratory protocol is in place to screen specimens for the most common parasites for this geographical location, which is Cryptosporidium and Giardia lamblia. This will be performed by Cryptosporidium/Giardia Antigen test.

Exceptions to this protocol include patients that have traveled outside of the United States, are in an immunocompromised status, and/or have had an admission to hospital with clinical symptoms of parasitic infection.

Refer to Mayo Medical Laboratories if Ova and Parasite is performed

Pass stool into a clean, dry container. 

--The use of a bed pan or a large plastic bag into a waste basket can be used to catch the specimen

--Collect stool from diaper lined with plastic. If infant or child has diarrhea, line the diaper with plastic wrap or use a pediatric urine bag placed over the rectum to collect a specimen that is not contaminated with urine.

CAUTION:  Never leave plastic wrap against a child's skin for more than 30 minutes at a time.

For EcoFix transport (green top): 

1)  Open the lid of the tube containing the liquid. 

2)  Using the built-in spoon, place small spoonfuls of stool (sample the bloody, slimy, or watery portions) into the tube until the liquid level rises to the red line.   

3)  If the stool is formed, try to sample small amounts from each end/side and the middle. 

4)  Mix the contents with the spoon, then twist the cap tightly closed and shake to mix well.
