Blood collected in wrong container/tube type

Separated plasma/serum sent room temperature or refrigerated

Storage/Transport Temperature

Whole blood must remain at room temperature at all times after collection until received in our lab.

Separated plasma/serum samples that have been frozen must be sent with enough dry ice to maintain a frozen state until received in our lab.

Specimen Preparation

Keep sample as whole blood for delivery to our lab within 24 hours of collection. If delivery cannot occur within 24 hours, separate plasma/serum from cells within 24 hours of collection. Freeze immediately at -20°C or lower.

Stability (from collection to initiation)

Whole Blood (ambient/room temperature): 24 hours
