Acceptable clinical specimens include sputum, bronchial specimens or tracheal aspirates, blood, skin or tissue biopsy, cerebrospinal fluid (CSF), bone marrow, body fluids and urine. Gastric aspirates are acceptable but must be neutralized immediately after collection prior to submission. Swabs are not recommended and should not be submitted; collect an aspirate using sterile saline.
A minimum of 5 mL of sputum, bronchial specimen, or tracheal aspirate maintained at 2-8°C and received within 7 days of collection.
Do not pool specimens. Pooling dilutes the specimen and increases the likelihood of contamination.
