I noticed that you said viral load samples should have a purple (lavender) top on the tube. I gave a sample for a pro viral DNA PCR test today, and the tube had a yellow top on it. I asked her about it, and she said that it was ok, and then I called the lab that set up the test and they said that it was ok, but I was just still curious if was because I know you said before it needs to have that purple top on it. Thanks in advance for you answer.

They are correct. Purple top tubes are the "recommended" tubes for plasma viral load. Yellow top tubes will work just as well. Both colored tubes will work for DNA PCR from cells. Green tops need to be avoided.
