Specimen Requirements

4 mL (min.1 mL) whole blood sodium heparin preferred, EDTA whole blood accepted
2 ml (min. 0.5 mL) bone marrow aspirate sodium heparin preferred, EDTA bone marrow accepted
2 cm (min. 1 cm) bone marrow core biopsy in 2-4 mL MPLN RPMI transport media
5 mm^3 fresh tissue in 2-4 mL MPLN RPMI transport media
4 mL (min. 0.5 mL) fine needle aspiration in 2-4 mL MPLN RPMI transport media
4 mL (min. 0.5 mL) fluids,cerebrospinal fluid (CSF), pleural fluid, synovial fluid, and pericardial fluid in sterile container with 2-4 mL MPLN RPMI transport media
10 mL (min. 5 mL) bronchoalveolar lavage in sterile container with 2-4 mL MPLN RPMI transport media

If RPMI media or MPLN RPMI transport media is not available, send in sterile saline.
