Welcome to XXXXXXX
Thanks for posting your query.

You had mentioned the index value of your HIV test. But every test will have a cut off reference value. It may differ from test to test according to the product and indicated by the manufacturers. Only with that reference value one can able to interpret your test result.
As the Western Blot is negative for you, it is very unlikely for you to have HIV.
Do you have any history of blood transfusion? Have they checked the blood of your husband?
Nowadays HIV is not dreadful and life threatening condition. It is like any other disease. There are good number of drugs available to treat HIV and one can live positively with HIV, decent and comfortable life without much problem for more than thirty years. In the year ahead a complete curable drug may likely to emerge at any time. So there is nothing to worry. There are wonderful drugs available to prevent the mother to child transmission of HIV also.
Relax and feel better.

Welcome back.

You had tested by method of ICMA. It indicates HIV reactive. But Western Blot is more confirmatory which was negative for you. False positive results with Antibody test may be possible in pregnancy and with certain illness.

Transmission of HIV, through hospital admission and fluid transmission are not a common entity. You can go for Antigen test like DNA PCR which will be more reliable and confirmatory. As your physician ordered for Viral load test, you can wait for the same. But it may come like viral load below undetectable level and difficult to interpret. DNA PCR will be more useful in this situation.
Good luck to you.

I can understand your concern.

HIV reactive means HIV positive. Rather than all discussions, especially in your case, we have to wait and see the results of viral load and CD4 count and come to a conclusion according to the outcome of the test results. Till then nothing will be conclusive.

Regarding the false positive results, certain autoimmune disorders like Rhematoid Arthritis, Systemic lupus Erythematosis, Hashimato's Thyroiditis and multiple pregnancies, repeated blood transfusions, Recent vaccinations, substance abuse,repeated hemo-dialysis can produce false positive results. That is some protein material common with these diseases and HIV can produce similar antibodies and it is the reason for false positive results.
So don't get tension and unnecessary confusion. Your results of viral load and CD4 count will reveal the situation.
