Hi Stressedandanxious, Up to 4 weeks after exposure to HIV most people experience flu-like symptoms for 1 or 2 weeks. This is known as the seroconversion period and is when antibodies are produced in response to the virus. After seroconversion, an HIV test is able to detect antibodies and therefore will be able to accurately detect infection. Our test has a window period of 12 weeks due to the fact that there must be a detectable level of antibodies for the test to be able to accurately detect infection. By 6 weeks it has been estimated that around 95% of people will have produced enough antibodies for our test to be able to detect infection. So yes, a negative result at 7 weeks is a good indication of your status as it is likely you are in the 95% of people who produce antibodies by 6 weeks however, you should retest at 12 weeks to know for sure. Hope this answers your query, if you need further explanation or have any other questions please feel free to leave them below. Thank you, Becky
