Processing
Follow all precaution for handling biological material. Use all appropriate Personal Protective Equipment (PPE). Allow blood samples to clot (15 mins). Separate the serum from the cells by centrifuging for 10 minutes. Store serum at 2-8°C until analysis. Samples should be protected from light. Exposure to direct sunlight can decrease bilirubin in samples by 50% with in one hour.
Storage
Refrigerated.
Stability
