hey,dear doctors,since I am in China,and in China we can buy HIV test strips from internet legally,and by self using.and here is my concern:so I bought one strip of Abbott Determine HIV from internet,and I got the package today,it comes with one Determine HIV strip,and a blood collection needle,one tampon.But the blood collection needle is seperated packed in a small plastic bag,but the custormer service explained that it sure is disposable.and I didnt think that much,and then I just followed the instructions getting ready to take the test by myself.And now I'm really worried about what if the blood collection needle wasn't disposable like they said?But I have used the 75% Alcohol to disinfect needle top before I started,and my question is what is the probability that I would probably get infected by the needle if it already had HIV virus on it.One more mention,it took about 3 days to deliver the package to my house,is that possible even if the needle had HIV virus and 3 days were enough to let it become eliminated?Thank you sooooo much for helping me!
