What tests should I order to check for worms from a cat? - briefly
To detect worms transmitted from a cat, consult your healthcare provider about ordering a stool examination and a blood test, specifically for intestinal parasites. These tests are effective in identifying the presence of worm infestations.

When considering the necessary tests to detect worms transmitted from a cat, it is essential to understand the types of parasites that can affect humans and the appropriate diagnostic methods. Cats can harbor several types of worms that are zoonotic, meaning they can be transmitted to humans. The most common types include roundworms, hookworms, and tapeworms. Each of these parasites requires specific testing protocols to ensure accurate diagnosis.
For roundworms, such as Toxocara cati, stool samples are the primary method of detection. A fecal flotation test is commonly used, where a small amount of the cat's stool is mixed with a solution that causes the worm eggs to float to the surface. These eggs can then be identified under a microscope. It is advisable to collect multiple stool samples over several days to increase the likelihood of detecting the eggs, as they may not be present in every sample.
Hookworms, like Ancylostoma tubaeforme, also require stool samples for diagnosis. The fecal flotation test is effective for hookworms as well, but in some cases, a fecal sedimentation test may be necessary. This test involves allowing the stool sample to settle, and then examining the sediment for hookworm larvae. Additionally, a complete blood count (CBC) can be useful, as hookworm infections can cause anemia due to blood loss.
Tapeworms, particularly Dipylidium caninum, are often diagnosed through the identification of tapeworm segments or eggs in the cat's stool. These segments can sometimes be seen with the naked eye and resemble grains of rice. A fecal flotation test can also be used to detect tapeworm eggs. In some cases, a tapeworm infection may be suspected based on the cat's history of flea infestation, as fleas are a common intermediate host for tapeworms.
It is crucial to consult with a healthcare provider or a veterinarian to determine the most appropriate tests based on the specific symptoms and exposure history. Regular deworming of cats and maintaining good hygiene practices, such as washing hands after handling pets and cleaning litter boxes, can help prevent the transmission of worms from cats to humans. Additionally, ensuring that cats are regularly tested and treated for worms can significantly reduce the risk of zoonotic transmission.
