Sorry one last anxious question. The Western Blot kit arrived on September 22 but I was unable to get to a lab for the blood draw until mid October. I think it was October 18. Would there be an issue with the serum separator tube (the tube with the yellow top) expiring in that time? When I got my blood drawn I’m pretty sure the lab technician checked the expiration date but I just never saw the expiration date, so now I’m getting nervous about that.
