If you use test paper to test, you can usually get the preliminary screening results in two hours, and draw blood to test HIV antibody. Generally, you can also get the preliminary screening results on the same day. If both methods are negative, the results can be reported at that time. If it is positive, it needs to be sent to the confirmation laboratory for confirmation experiment, which will take a little longer. If it's fast, it'll only take a day or two. If there are many samples, the time will be a little longer, but it will not exceed 10 working days. Aware can test herself without drawing blood. I wish your cat health!
