Blood samples are stable at room temperature (15ºC to 25ºC) for one day or at 2º to 8ºC for up to 5 days. Blood samples should not be frozen at any time.
DNA sample stability is dependent on the methodology used for the isolation. In general the DNA should be stable and can be shipped ambient or cold, following the directions below.
Specimens from outside facilities should be packaged according to standard medical safety practices. Refrigerate samples if stored overnight prior to shipping. In hot weather, include a cool pack in the shipping container. Do not allow the specimen to freeze at any time. Package the completed test requisition inside the packaging container with the specimen. Please ship by overnight priority.
Specimens should not be shipped on Fridays, Saturdays or the day preceding a holiday.
