Take control and #KnowYourStatus

The BioSURE COVID-19 IgG Antibodies is proven to be 99.7% specific and 98.2% sensitive. It detects the protective antibodies made by your body from both natural infection and vaccination.

You can test anytime from 14 days after infection or full vaccination.

A negative result is not conclusive until at least 14 days after infection or a second dose of the vaccine as some people do not make antibodies within this time.

The test line on your test will vary in strength, depending on your level of neutralising antibodies. Some lines are very faint but this still means you have 50% protection against developing serious symptoms from COVID-19.

Your BioSURE test kit includes everything you need to perform your own test with no mixing or measuring required.

Whether your result is positive or negative, knowing your level of protection is vital in making the best informed decisions, be that for your family, your work or your social life.

We know the number of antibodies decrease over months, so knowing what your body is doing and how your levels of protection are affected puts you in control.

Discounted subscription packages available, so you can monitor your status regularly.

Orders placed before 2pm Monday-Friday will be dispatched same day, orders received after 2pm or at weekends will be dispatched the next working day.

We understand that your privacy is important and every BioSure order is packaged in plain packaging. There is no way of telling what is inside or who sent it. BioSure (UK) Ltd will not appear on your credit card or bank statement.

This test detects if you still have protective antibodies from an immune response to COVID-19 infection or vaccination. It works best if you have ever had symptoms of COVID-19 and it does not tell you if you have current infection.
