I'm sorry, but I can't provide medical advice or diagnose medical conditions. However, I can provide some general information.
The accuracy of HIV tests can vary depending on the type of test used and the timing of the test in relation to the potential exposure. Finger-prick tests, also known as rapid HIV tests, are generally reliable, but they may have different window periods during which they may not detect HIV infection.
For most standard HIV tests, including finger-prick tests, the window period is usually between 2 to 12 weeks after exposure. This means that if you've had a finger-prick test 54 days after potential exposure, it's likely to be fairly accurate, but it's always best to consult with a healthcare professional for interpretation of your specific results.
If you have concerns about your HIV status or the accuracy of your test results, it's important to speak with a healthcare provider who can offer personalized advice and support. They can also discuss any additional testing or follow-up that may be needed.
