Frequently Asked Questions


Can samples from different sources (for example feces and urine) be combined for testing?
It's recommended to avoid mixing samples, as introducing unknown substances could potentially cause unintended reactions during the testing process.

If a puppy has been vaccinated for Parvo, could the Parvo antigen test shows a positive result?
Yes, it's possible. The Parvo vaccine commonly contains live components, which can result in the excretion of antigens post-vaccination. We recommend waiting for at least 14 days before performing a Parvo antigen test again.

Does the Parvo Antigen test show false positives due to vaccination?
No, the Parvo Antigen Test specifically detects antigens and does not cross-react with antibodies produced by vaccination.

What should I do if the test doesn't start or if too much feces is added to the test?
Adding excessive feces can cause the running buffer fluid to thicken, potentially preventing the test from running properly. If too many fecal particles or mucus are added to the sample field, it could clog the test. To resolve this issue, gently move excess feces aside in the sample field using the end of the cotton swab, and then add a drop from an unopened tube.

The liquid in the test tube appears dark in color. Can I still use it?
Be careful! Excessive feces in the sample tube can lead to the running liquid becoming too thick, which may impede the test process. A dark color in the running liquid is an initial indication of this issue. There's a higher risk of obtaining brown test lines when too much feces is used.

If the C and/or T lines are already visible before performing the test, can the test still be used?
The faint, light blue lines visible before the test are auxiliary lines. They are designed to indicate to the user beforehand the areas where lines are expected to appear later, depending on the test result. Additionally, these lines serve as a quality control measure for our product. The light blue color is washed out during the test run.

Is it problematic if the fecal sample contains cat litter?
Samples containing cat litter can interfere with the test. Cat litter often undergoes chemical treatment, which may negatively impact the test results. Therefore, it's advisable to avoid sampling from areas with cat litter.

If the feces are very crumbly, can I moisten the cotton swab with the buffer beforehand to make it easier to pick up the fecal material?
Yes, you can do that. It's recommended to moisten the cotton swab with the buffer beforehand to make it easier to pick up the fecal material. This helps the material adhere better to the swab, allowing for smoother transfer to the sample vial without any issues.

When should a Giardia retest be performed?
A retest after 2-3 weeks can confirm successful treatment with a negative result. Additionally, if the test line gradually decreases over time, it may indicate successful treatment.

If a moderate to strong test line persists for several weeks after completing treatment, it's highly likely that an active infection is still present, and the animal is shedding infectious cysts. Please note that some animals may continue to shed cysts chronically without exhibiting clinical signs. Alternatively, reinfection may have occurred.

How long are Parvo antigens detectable?
Parvo antigens are typically excreted for a short period. The virus is shed in feces for approximately 10 days, occurring 3-4 days after infection and before symptoms onset.

Note: Parvoviruses can also be introduced into a household from external sources, such as clothing or objects, as they are highly contagious.
