As whole blood derived platelet units typically contain 5.5 Ã 10 10 platelets, 4â6 units must be âpooledâ to make a dose. Many apheresis-derived platelet collections contain two or three times the required minimum of 3 Ã 10 11 platelets and thus are âsplitâ to make multiple platelet doses from a single collection.

A judicial panel is a set of judges who sit together to hear a cause of action, most frequently an appeal from a ruling of a trial court judge. Panels are used in contrast to single-judge appeals, and en banc hearings, which involves all of the judges of that court. Most national supreme courts sit as panels. In the United States, most federal appellate cases are heard by three-judge panels.
The federal courts are composed of three levels of courts. The Supreme Court of the United States is the court of last resort. It is generally an appellate court that operates under discretionary review, which means that the Court can choose which cases to hear, by granting of writs of certiorari. There is generally no right of appeal to the Supreme Court. In a few situations (like lawsuits between state governments or some cases between the federal government and a state) it sits as a court of original jurisdiction. The United States courts of appeals are the intermediate federal appellate courts.
