Which specimen must be transported chilled in an ice slurry?

Ammonia rises rapidly at room temperature as cells continue to metabolize, so the tube is chilled in an ice and water slurry and delivered immediately. Bilirubin is protected from light rather than chilled, and cold agglutinins must be kept at body temperature because cooling causes the antibody to bind red cells. A CBC is transported at room temperature.
