Strongyloidiasis is a parasitic infection that can range from mild symptoms to life-threatening complications. It is caused by the roundworm Strongyloides stercoralis, which enters the body through contaminated soil and can persist for decades if untreated. The Ova & Parasites with Giardia Antigen stool test is the most important test for diagnosis because it directly identifies the parasite larvae in stool samples.

Strongyloidiasis is caused by the roundworm Strongyloides stercoralis, which lives in contaminated soil in tropical and subtropical regions. The parasite enters your body when your bare skin comes into contact with infected soil, typically through your feet. Once inside, the larvae travel through your bloodstream to your lungs, are coughed up and swallowed, then mature into adult worms in your small intestine where they can reproduce and cause infection for decades if left untreated.
The Ova & Parasites with Giardia Antigen stool test is the most important test for strongyloidiasis because it directly identifies Strongyloides stercoralis larvae in your stool samples, providing definitive proof of infection. This specialized test examines multiple stool samples to detect the roundworm parasites that are responsible for the condition. Additionally, the HTLV-I/II Antibodies test is essential for risk assessment, as co-infection with Human T-Cell Lymphotropic Virus significantly increases the risk of severe complications like hyperinfection syndrome, which can be life-threatening and requires more aggressive treatment.
You should get tested if you have traveled to or lived in tropical or subtropical regions and experience persistent digestive symptoms like diarrhea, abdominal pain, or skin rashes. Testing is especially important if you have a weakened immune system from conditions like HIV, cancer treatment, or long-term steroid use, as the infection can become severe. You should also consider testing if you notice recurring red, itchy skin tracks on your body, particularly around your buttocks or thighs, or if you have unexplained respiratory symptoms after potential soil exposure.
