THE SHORT ANSWER

Follow the instructions for your exact test, including sample collection, timing and what to do after a negative result. Products can differ.

What is useful to understand?

Before starting, read the entire instruction sheet and check expiration information. Set a timer rather than estimating the reading window. If symptoms continue or you are at higher risk, ask a clinician about further testing and care instead of assuming a single negative result settles the question.

What can you ask or do next?

  1. Check the product instructions and expiration information.
  2. Collect the sample exactly as directed.
  3. Read the result in the stated time window.
  4. Follow the instructions for repeat testing.

One more question

Can I interpret the test after the reading window?

Follow the manufacturer instructions; a result read outside the specified window may be unreliable.
