Hi Anonymous Anxiety, Thank you for sharing your story. If there was a faint test line, I would have thought that the doctor performing the test would have recognised this as a positive result. There is a chance of the result being a false positive as it is strange that your doctor said that the test line was reluctant to show but it is good practice that you have followed up with a western blot test. Did you receive the results back from this test? Given the window period, I would say that any result from the second test would be accurate and conclusive and would definitely show whether the fourth generation test result was a false positive or not. Since I am only trained in reading results/giving advice on the BioSURE HIV self test, I am unfortunately unable to comment on the reliability of your previous test results and would recommend to get in contact with your doctor to discuss your results further. Sorry that I cannot be of more help. Wish you all the best, Becky
