Ova and Parasites: Basic OAPB
|Method(s)||Concentrate technique/Trichrome stain/light microscopy|
Stool, urine, sputum, bronchial wash and/or lavage.
Inpatient: Stool collected in a dry, clean container and delivered immediately at room temperature. Outpatient: Several spoonfuls of stool transferred to a vial with SAF Fixative and delivered within 72 hours at room temperature. Urine, sputum, and bronchial specimens should be refrigerated and delivered within 72 hours.
Three specimens collected on separate days should be submitted per standard recommendations as parasites may be shed intermittently. Further, only 1 specimen per day will be reimbursed by Medicaid and private insurers; therefore, only 1 specimen per day will be accepted for testing.
Stool preserved in SAF: 1 month at Room Temperature. If specimen is unpreserved the stool is stable for 24 hours at 4°C. Urine, sputum, and bronchial specimens are stable for 72 hours at 4°C.
Specimen collected on swab, stick or diaper. Specimens contaminated with oil, barium or urine. Dry specimens are inappropriate for testing.
The "Basic" exam should be ordered if the patient's immune status or travel history warrants examination for only intestinal parasites.
|Preferred Specimen Collection Device(s)|
No ova and parasites seen.
