A physician orders a nurse to collect a stool specimen from a client and send it to the laboratory for an Ova and Parasite (O&P) test. Based on this information, what would the nurse anticipated being detected by an O&P test?
A) Frank blood
B) Bile pigments
C) Tapeworm eggs
D) Occult blood
C
Feedback:
The O&P test detects the presence of intestinal parasites and ova. Thus, it can detect tapeworm eggs. It does not detect the presence of frank blood, bile pigments, or occult blood. Frank blood is visible to the naked eye. Bile pigments are normal constituents of stool that give it its characteristic yellowish-brown color. Occult blood is detected by the Hemoccult test.
