Tritrichomonas foetus (rtPCR)
The Tritrichomonas foetus (rtPCR) test uses real-time polymerase chain reaction (rtPCR) to detect Tritrichomonas foetus DNA, a protozoan parasite that primarily infects the large intestine of cats, causing chronic diarrhea and colitis. Infected cats, particularly those in close-contact environments like catteries or shelters, may experience persistent, foul-smelling diarrhea that can be challenging to treat with standard therapies. The rtPCR method provides high sensitivity and specificity, allowing for the accurate detection of T. foetus even at low levels, which is critical for early diagnosis and appropriate management. This test is especially valuable for identifying T. foetus in symptomatic cats and preventing further spread in multi-cat environments through targeted treatment and isolation measures.
Test name
Tritrichomonas foetus (rtPCR)
Test Code
5030
Section
Molecular Diagnostics
Species
Feline
Specimen
5g fecal sample
Collection Guidelines
- Ideally, fecal samples should be taken directly from the rectum. If samples are collected from the ground, they should be taken from the surface of a freshly deposited stool.
- An appropriate sample size is 5g in a leak proof sterile container.
- Preferably submit the sterile container in a zip-locktype plastic bag
Turnaround time
14-21 days
Packing Instructions
Label each sample with the animal’s name and a unique identifier, using a permanent marker or a secure adhesive label. Ensure the submittal form is completed with the animal’s information and relevant medical history.
