A positive result means the test detected traces of blood not visible to the eye. This can happen for a range of reasons, from minor irritation to concerns that may need medical attention. At-home kits provide a screening signal and don’t diagnose the cause.

• Review the instructions for any follow-up steps noted by the manufacturer.
• Check that the test wasn’t expired or used outside the directions.
• Consider sharing the result with a healthcare professional for guidance.

Because results can be influenced by how and when the test was used, a professional can help interpret what it may mean for you and recommend next steps if needed.

At-home stool tests are one noninvasive way to screen for signs that could be associated with colorectal concerns, often by checking for hidden blood. They’re typically used as a screening tool—not a diagnosis.

• Some people choose them when they want a simple, at-home option.
• Timing and frequency vary by product; always follow the kit’s directions.
• A healthcare professional can help decide which screening approach fits your situation.

You can find these kits in our Home Health Tests section online. Many shoppers also use FSA/HSA funds for eligible items—look for eligibility indicators on the product page and save your receipt.

It’s reasonable to take action any time your kit shows a positive result or an invalid reading. While at-home tests are convenient screening tools, only a healthcare professional can evaluate what your result might mean for you.

• If positive: follow the kit’s instructions and consider contacting a professional.
• If invalid or expired: repeat with a new, in-date test.
• If you notice ongoing changes or symptoms: seek timely medical guidance.

Keep your results and packaging handy when you reach out—they can help a professional understand which test you used and how it was performed.

Most kits in this category are designed to screen for hidden (occult) blood in stool, which can be an early sign that something in the digestive tract deserves a closer look. They don’t identify a specific illness.

• Screening focus: detect traces of blood not visible to the eye.
• Use case: prompt a conversation with a healthcare professional if results are positive.
• Limitations: results can be affected by usage and are not diagnostic.

Always read the product details and instructions so you know exactly what a particular kit is intended to screen for and how to use it correctly.

Setup and disposal can vary by kit, but the basics are usually straightforward.

1. Read the instructions from start to finish before opening anything.
2. Collect or test as directed (some use test pads placed in the toilet).
3. Wait the indicated time and compare the result window or color guide.
4. Seal used materials and place them in household trash unless the instructions say otherwise. Avoid flushing plastics.

Additional tips:

• Wash hands and clean any surfaces you used.
• Store unused tests at room temperature and check expiration dates.
• If anything seems unclear, the product insert and customer reviews on Walmart.com can offer helpful context.
