What is a home sampling kit?
Home sampling allows you to self-test at home. After receiving your test kit, you collect a sample of blood from your finger, then post your sample to the laboratory.
A week or so later they will contact you with the result.

The HIV test may not detect an infection that was contracted very recently – the test is highly accurate after 4 weeks, and almost 100% accurate after 8 weeks.
If you had unprotected sex in the last 6-8 weeks, it is recommended that you test immediately and also complete a new test in 6 weeks to be sure of your status.
