          Light Blue Topped

                                                          Light Blue-Topped







                        • Used for coagulation studies (PT, APTT, PTT)





                        • Primary additive is sodium citrate, which binds

                            with calcium to prevent blood from clotting






                        • This tube must be completely filled in order to

                            maintain the anticoagulant-blood ratio







        NOTE: The tube should be inverted to prevent clotting.
