Storage
Refrigerated.
Stability
Refrigerated: 7 days at 2–8°C; Frozen: 3 months at -20°C. At ACCU: Refrigerated: 7 days; Frozen: 2 weeks. Lipemia: Gross lipemia has been shown to cause a decrease in the apparent progesterone concentration. The use of an ultracentrifuge is recommended to clear lipemic samples.
