New product announcement!!

Tritrichomonas Foetus Antigen Test


Brief Introduction

Tritrichomonas foetus is a type of protozoa, which is easy to infect young cats and cause diarrhea and bloody stool. Some healthy adult cats infected with Trichomonas foetus will not have obvious external symptoms, while young cats or cats with low immunity will have obvious symptoms.

The Felivet TRF Ag Test is a lateral flow immunochromatographic assay for the qualitative detection of Tritrichomonas foetus antigen (TRF Ag) in cat’s feces specimen.

Assay Time:  5-10 minutes

Specimen: feces



R & D background

Trichomonas fetus is a single-celled, flagellated protozoan parasite that inhabits the colon and terminal ileum of felines. Infected cats may be asymptomatic or may have clinical symptoms, including foul-smelling large bowel diarrhea. T. foetus infection is common in, but not limited to, high-density young purebred cat populations. Testing for this parasite is still not routine in most veterinary clinics, and Trichomonas fetus is often misdiagnosed as Giardia. T. foetus should be considered for specific testing in cats with colorectal diarrhea, especially those for which conventional diagnosis and treatment of other causes of colorectal diarrhea in cats have failed to achieve clinical solutions. Correct identification of T. foetus is essential for the treatment of feline trichomoniasis.


How hard to distinguish Giardia and T. foetus

In treatment, giardia and T.foetus use different drugs. During treatment, it is necessary to take precise medication for the disease, otherwise the therapeutic effect will not be achieved, and it may even lead to some side effects.


Because of the subtle morphological differences between the two, it is difficult to distinguish them by ordinary stool microscopy.

Clinically, both cause chronic diarrhea, and many cats infected with T.foetus do not have any clinical symptoms.


Diagnostic method


1. Direct fecal smear

Simple and cheap, but not very sensitive

2.Fecal culture

The price is relatively cheap, and the sensitivity is slightly better than that of the fecal smear. But the operation is more complicated

3. PCR Test

High sensitivity, but expensive and time-consuming


4. Colloidal Gold Rapid test

We have successfully developed another detection method for the diagnosis of T.foetus using colloidal gold immunolayer technology.

We are the first in China to use this technology to diagnose T.foetus. Product performance verification has been carried out in China, and so far, the compliance rate is 100%.


Compared with other detection methods, the advantages of our products are: easy operation, no need for other instruments; good sensitivity and specificity, support and Giardia's combo test, one-click differential diagnosis between the two; cost-effective.
