Essential Ways To Detect The Presence of Parasitic Infection


Parasitic infections can be tricky. What sets them apart from other types of infection, is the fact that with parasitic infections, it usually takes time for one to notice them due to the parasites’ slow mode of operation. Parasites are organisms, in our case, microorganisms that board their host somehow, and start feeding off of them in order to survive; which usually ends up with the host being depleted.

The effects of parasites on a host differs from some parasites to others; some parasites are capable of surviving for a long time without causing significant changes or attracting attention to themselves. Others, however, are less careful; a short while after they enter a host, they start rapidly growing in population and colonizing the body which results in parasitic infections.

Depending on the growth stage, one can either treat a parasitic infection using something as simple as, parasite cleansing supplements, or resort to a more intense course of medication. One must keep in mind that parasites thrive in hot and humid conditions which is one of the factors you should watch out for, if you are suspecting that you might have a parasitic infection. While on the subject, medical experts are always recommending that you put an end to infections before they start spreading which is why we are supplying you with several essential ways you can use to check for the presence of parasites in your body.

Blood Tests

Like any other body component, when you need to test for the presence of something in your body, an easy way is a simple blood test. What doctors do is that they take a drop of blood and they smear it on a glass slide.

Then, they stain the sample with some sort of dye so that they can easily detect parasites. After that, the slide is placed under a microscope and the sample is examined for possible contamination.

This test, however, does not show all types of parasites which is why there is another method. Said method goes like this: a blood sample is sent to a lab where they test for the presence of toxins produced by parasites or antibodies which were released by the body as a defense mechanism.

Keep in mind that the first method can only detect certain types of parasites; such as, filariasis, malaria, or babesiosis. Meanwhile, the second method is a lot more accurate and thorough which is why it is more recommended to perform a lab blood test rather than a visual one.

Fecal Exams

Fecal exams; also known as, ova and parasite tests, are a more specific way to detect intestinal parasites. To be more accurate, the test is designed to look for any sort of parasite that could have a possible effect on stool.

According to the U.S Centers for Disease Control and Prevention, for that test it is optimal if you provide about three stool samples taken on the span of several days; in order to minimize the chance for error due to certain atmospheric conditions or anomalies.

Ova and parasite tests look for three things; the effect that a certain type of parasite may have had on stool, or the presence of ova that has been produced by a parasite, or the presence of the parasite itself.

Again, keep in mind that the way this test is usually carried out does not show all types of parasites so, it is up to you and your health care provider to instruct the lab on which equipment and stain solutions to use when examining stool samples.


In case the fecal exam does not turn out with much information, the doctors may have to go into your body to look for possible fugitives. A simple endoscopy or colonoscopy is the usual protocol.

A doctor will either go through the mouth (endoscopy) or the rectum (colonoscopy), using a thin scope. They will be looking for the parasite itself or signs that indicate the existence of a parasite.

Visual Scans

X-Rays, MRIs and CAT scans are sometimes used in severe cases of parasitic infections; when an organ is suspected to be significantly damaged. This process looks for lesions, as well as, damaged organs.

Final Thoughts

The point at which you decide on getting tested can be critical to your health. Parasitic infections are not fun at all. They cause a lot of pain and, if untreated promptly, may result in severe illnesses which may progress later on. Therefore, it is highly advised that you pay attention to any suspicious irregularities in your body.
