Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like abdominal pain, fever, or skin rashes, or if you’ve lived in or traveled to regions where schistosomiasis is common. It can also be used to monitor treatment effectiveness or check for reinfection.

What to Expect Before the Test

You’ll need to collect all urine produced in a 24-hour period (starting and ending at the same time each day) into a special container. Follow your provider’s instructions carefully to ensure accurate results.

What Happens During the Test

The collected urine sample is analyzed in a lab to detect specific proteins linked to Schistosoma parasites. No special preparation is needed beyond following the urine collection guidelines.

What the Results Mean

Positive results suggest the presence of Schistosoma antigens, which may indicate an active infection. Negative results mean no detectable antigens were found in your sample during that period.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What causes schistosomiasis?
Schistosomiasis is caused by contact with contaminated freshwater where Schistosoma parasites live in snails. Swimming, wading, or drinking untreated water in these areas increases risk.
How is schistosomiasis treated?
Treatment typically involves oral medication to kill the parasites. Your provider may recommend follow-up tests to confirm the infection is cleared and monitor for recurrence.
Can this test detect past infections?
This test primarily detects active infections by measuring recent parasite activity in urine. For past infections, other tests or bloodwork may be needed to assess long-term effects.
