  • For patients where Histoplasma, Blastomyces, Coccidioides or Cryptococcus are suspected (e.g., HIV patients may be at risk for these agents), place 8 mL blood into SPS (Liquod) culture tube (blood or bone marrow) or 6 mL in Dupont Isolator tube (blood only). If 8 mL blood cannot be obtained, place minimum of 1.5 mL blood into an 8 mL (SPS) fungal culture tube. Specify suspected organism on request form.
  • In infants (less than 11 lb/5 Kg)with suspected Malassezia or Histoplasma, inoculate an SPS tube. Specify suspected organism on request form.
