Hiv antibodies test?

My blood was collected yesterday for an HIV antibodies test (I think it is antibodies not another test). How does the test work in terms of the number of times they test the blood sample? What I mean is if the first time they test it results in positive do they do additional tests on the same sample without collecting from me again hence delaying the results? The reason I ask is because it's been more than 24 hours since my blood was collected and I haven't heard back from my doctor. Earlier blood test results were shared within 24 hours. Thanks.

Thanks to everyone who answered my question. The results were delayed because, I guess, the doctor ordered Hepatitis and other blood tests along with HIV. All of them were non-reactive which I am assuming means negative.

Most labs have a protocol to repeat a test and run more than one type of test before calling a positive.

However, 24 hours is not a long time. Most labs ask for a week finish results. Testing is very expensive, and they often run many samples at once, taking many, many precautions to ensure the results are correct. It's not unusual for results to take different links of time to come back, it would be needless worrying to try to read results into that.

well hopefully you are not infected because if you were and samples are in 24 hours they would have reached soon as possible. and it was very brave of you to get tested best of luck either or.

you should get the results by tomorrow


good luck man

yes, dude, u are right.
but as a HIV positive myself, i need to tell u that no matter what the result is, u need to keep peace.
i will take myself for instance, i just felt nothing when i was tested HIV+, so i could live some 6 yrs all right...
however, a guy i knew some 2 yrs ago on positivesingles.com just have gone, i guess it was the anxiety killed him rather than the disease.
so... u need to trust me, and good luck!
