What's this test for?

This test is ideal if you're experiencing persistent diarrhea, stomach cramps, bloating, nausea, or unexplained weight loss. It helps identify parasitic infections that may be causing your digestive discomfort, especially if you've traveled internationally, consumed contaminated water, or live in areas where parasites are common. Many people use this test when their stomach issues don't improve with standard treatments and they want to rule out hidden infections.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining whether parasites or Giardia were detected and what this means for your digestive health. These notes include personalized recommendations like dietary adjustments, hydration strategies, treatment options, or whether you should follow up with a gastroenterologist or infectious disease specialist. You'll also get the standard lab report and can track your results over time using our trends feature, which is especially helpful if you need retesting after treatment.

What's included in this test?

This test measures Giardia Ag, Eia, Stool and Ova And Parasites, Conc And Perm Smear. This comprehensive stool test checks for the presence of parasites through microscopic examination (ova and parasites screening) and specifically tests for Giardia using a highly sensitive antigen test. The combination ensures maximum detection accuracy for Giardia, which is one of the most common intestinal parasites causing digestive symptoms, along with other parasitic infections that may be affecting your gut health. Together, these measurements provide a thorough assessment of parasitic causes behind your gastrointestinal symptoms.

How should I prepare for this test?

You'll need to pick up a special stool collection container from the lab before testing. Avoid bismuth products, barium (wait 7-10 days after exposure), antimicrobial agents (wait 2 weeks), and gallbladder dye procedures (wait 3 weeks) as these can interfere with results. Keep your specimen at room temperature and label it with your name, date, and time of collection before returning it to the lab.

When will I get my results?

Your test results will be ready in approximately 5 business days after the lab receives your stool sample. This turnaround time allows for thorough microscopic examination and antigen testing to ensure accurate detection of parasites and Giardia.

Who should consider getting this test?

This test is important for anyone with persistent digestive symptoms like diarrhea, stomach pain, or bloating that hasn't responded to typical treatments. It's especially recommended if you've recently traveled internationally, consumed untreated water, work in childcare settings, or have been exposed to someone with a known parasitic infection. People with weakened immune systems should also consider this test if experiencing gastrointestinal issues.

What symptoms indicate I may need this test?

Common symptoms that may indicate a parasitic infection include persistent or recurring diarrhea, stomach cramps or pain, bloating and excessive gas, nausea, fatigue, and unexplained weight loss. You might also experience greasy or foul-smelling stools, loss of appetite, or mild fever. If these symptoms persist for more than a few days or started after travel or water exposure, testing is recommended.

What is Giardia and why does it matter?

Giardia is a microscopic parasite that causes an infection called giardiasis, one of the most common intestinal parasitic infections worldwide. It spreads through contaminated water, food, or surfaces and causes symptoms like watery diarrhea, stomach cramps, bloating, and nausea. Detecting Giardia is important because it requires specific treatment and won't resolve on its own, and untreated infections can lead to dehydration, malnutrition, and chronic digestive problems.

What happens if my test detects parasites?

If parasites or Giardia are detected, your doctor notes will explain which organism was found and recommend appropriate treatment, typically prescription antiparasitic medications. You'll also receive guidance on preventing reinfection through proper hygiene, water safety, and food handling practices. Most parasitic infections are highly treatable with medication, and symptoms usually improve within days to weeks of starting treatment.

How can I prevent parasitic infections?

Prevent parasitic infections by practicing good hand hygiene, especially before eating and after using the bathroom or changing diapers. When traveling, drink only bottled or properly treated water, avoid raw vegetables and fruits you can't peel yourself, and be cautious with ice in drinks. At home, wash produce thoroughly, cook meat to proper temperatures, and avoid swallowing water while swimming in lakes, rivers, or pools.
