Any citizen that has taken a lateral flow test and has come back positive will know – all Covid lines aren’t created identical.

Some lines across the T section, which specifies if you have coronavirus or not, come back so faint you can barely see them, while others are even superior and bolder than the line above it.

This can be quite confusing – does the boldness of the line actually have anything to do with your health? Does a fainter line mean you are less infectious? And does a bold line mean you are more infected than others?

Well, the government has issued some guidance on what to do should you get a faint line, or one a lot stronger. According to the Gov website of the UK, lateral flow tests can be less subtle when a person has lower levels of the virus in their system.

However, the Government guidance states that “… even faint lines, shows the test is positive”.

It further says: “Result lines may appear smudged or faint, but they are still valid results and must be reported.”
