Collection Instructions
Collection Instructions:
NOTE: Aspirated material is preferable to swab specimens because
the chances of contamination by surface bacteria are decreased and
adequate volume is available for optimal organism recovery.
DEEP WOUNDS OR ABSCESSES:
- Disinfect surface of the wound with 70% alcohol and then with anti-septic iodine solution. Allow disinfectant to dry before collecting specimen.
- Using a 3 to 5mL syringe with a 22 to 23 gauge needle, aspirate the deepest portion of the lesion.
- Aseptically transfer aspirated material to sterile, leak proof container.
- If swab must be used, obtain an Aerobic Transport System swab.
- Remove cap and sample deep within the wound, avoiding any surface contamination.
- Return swab to culturette sleeve, crush ampule of transport media and gently push cap down until swab is saturated with the media.
SUPERFICIAL WOUNDS:
- Disinfect surface of the wound with 70% alcohol and then with anti-septic iodine solution. Allow disinfectant to dry before collecting specimen.
- Aspirate or swab deepest part of wound rather than lesion surface, following guidelines for deep wounds.
SURGICALLY OBTAINED SAMPLES:
- Submit fluid or pus in sterile, leak proof container; use an Aerobic Transport System for swab specimens.
ULCERS:
- Disinfect surface of the wound with 70% alcohol and then with anti-septic iodine solution. Allow disinfectant to dry before collecting specimen.
- Remove any overlying debris.
- Aspirate exudate from or swab base of ulcer, following guidelines for deep wounds.
