How long do blood samples keep?

If a wet blood sample is kept at room temperature, in most cases it should be in the laboratory for testing within eight hours of the blood collection event. If testing cannot be completed within that 8-hour timeframe, the sample is typically placed in cold storage at +2°C to +8°C for no longer than seven days.

How long can blood samples be stored at room temperature before testing?

Whole blood samples should not remain at room temperature longer than 8 hours. If assays are not completed within 8 hours, samples should be stored at +2°C to +8°C no longer than 7 days. If assays are not completed within 7 days, or the sample is to be stored beyond 7 days, samples should be frozen at -15°C to -20°C.

How long can serum samples be stored at?

Storage and shipment of serum samples Serum should be stored at 4–8°C until shipment takes place, or for max. 7 days. When kept for longer periods, serum samples should be frozen at −20°C or lower and transported to the testing laboratory on frozen ice packs.
