The RBC antibody identification test is used to name the specific antibody or antibodies that are present to determine if they are likely to be clinically significant, i.e., if they are likely to cause a transfusion reaction.
Roku features several cable channels like FOX, A&E, History Channel (and dozens more) that offer a combination of free content, plus a full line-up of channel content you can access with your cable subscription credentials.
Roku is a great alternative to cable if you have a netflix account and use one of the other pay per episode services. They have a lot of sports channels now (NBA, MLS, MLB) so you can pay al la carte for those. For football, you may need an antennae but that's cheap enough if you are in the right area for it.
