1 swab, ESwab
Specimens should be delivered to the microbiology laboratory as soon as possible. Culture of specimens older than 24 hours may lead to a reduction in recovery of microorganisms. Do not freeze specimens at -20C, or in a frost-free freezer. Specimens should be collected in sterile leakproof containers without preservatives. A sterile anticoagulant such as heparin or SPS may be used in collection tubes to prevent clots in body fluids. Swab-collected specimens and fecal specimens are NOT recommended.
See ESwab collection video for more information

For urine, three specimens, one per day for three consecutive days are recommended. For gastric lavage, three early morning specimens collected on separate days are recommended. Specimens must arrive in laboratory within 4 hours. Volumes >15 mL will NOT be accepted. For blood and bone marrow AFB culture, see CULTURE, AFB, BLOOD.
