What is the Add-On: Macroscopic Examination for Worms By Genova Diagnostics?

This test is an add-on to the full GI Effects profile.  This add-on test specifically looks for the presence of worms.

The macroscopic stool test for worms, also known as a visual inspection of stool samples, involves examining stool samples with the naked eye or under a microscope to detect the presence of parasitic worms or their eggs. 

This diagnostic approach helps identify various types of intestinal parasites such as roundworms, tapeworms, and hookworms, aiding in the diagnosis and treatment of parasitic infections.

How is the Add-On: Macroscopic Examination for Worms By Genova Diagnostics Clinically Relevant?

When incorporated into the GI Effects Profile by Genova Diagnostics, the macroscopic stool test for worms enhances the diagnostic accuracy and enables tailored treatment strategies, optimizing patient care and outcomes in the management of GI disorders and parasitic infections.

Undiagnosed parasitic infections can have many symptoms, including:

• Nausea and vomiting
• Unexplained weight loss
• Fatigue or weakness
• Visible worms or eggs in stool
• Itching or irritation around the anus or genital area
• Disturbed sleep due to itching (especially in cases of pinworms)
• Anemia (due to blood loss in cases of hookworm infection)
• Allergic reactions (such as skin rashes or respiratory symptoms) in response to certain parasites
• Digestive disturbances, including bloating and flatulence
• Appetite changes, either increased or decreased
• Fever or flu-like symptoms in severe cases of infection

It's important to note that symptoms can vary depending on the type of parasite and the severity of the infection. Additionally, some individuals may be asymptomatic carriers of certain parasites.
