Sorry another follow up. When the kit arrived I put the ice pack in the freezer per your instructions but I did not put the serum separator tube (yellow top) in the fridge of freezer. Was that a mistake? In retrospect, I feel very silly for not going to a lab right away. I had some work stuff and obligations that made me delay getting the blood draw. Let me know if I need to redo the Western Blot. I am very concerned about infecting my partner if the test is incorrect.
