Collection and Transport of Sample for Fecal Ova and Parasites

  • Collect sample in a bedpan, avoiding contamination with urine.
  • If patient is at home, collect specimen in Stool Collection Commode or have the patient put plastic wrap over toilet bowl.
  • At least 1 mL (size of a walnut) of sample is needed. Do not fill stool above the fill line on the transport vial
  • If the specimen cannot be transported to the lab within two hours, inoculate stool into a transport vial (Total Fix) which can be obtained from Customer Service (802) 847-5121. Transport to the lab within 72 hours.
  • All vials should be inverted several times so the sample and preservative are well mixed.
