What is a lateral-flow test?

A lateral-flow test is a type of diagnostic test that uses a small, portable device to detect substances in a sample, like saliva or urine. It's often used for testing things like pregnancy or infections, and it gives results quickly, usually within 15 minutes. The test involves placing the sample on a test strip and waiting for a visual result, which might appear as lines on the strip.

How do I use a lateral-flow test?

To use a lateral-flow test, follow the instructions provided with the test kit carefully. Generally, you'll need to collect a sample (such as a drop of blood, saliva, or urine) and apply it to the test strip. Then, you add a few drops of a special liquid to the strip. Wait for the amount of time specified in the instructions, and then check the results. The appearance of lines on the test strip will indicate the result.

Are lateral-flow tests accurate?

Lateral-flow tests are generally reliable for many purposes, but their accuracy can depend on the quality of the test and how well you follow the instructions. While they provide quick results, they might not be as precise as more comprehensive tests performed in a lab. If you have concerns about your health or if the test results are unclear, it's important to consult a healthcare professional for further advice.
