Swabs
| Site | Container | Method |
| EYE- Bacterial | Charcoal Transport medium | Hold the swab parallel to the cornea and gently rub the conjunctiva in the lower eyelid. Place the swab inside the transport medium. |
| EYE - Chlamydia | See Chlamydia | |
| EYE - Viral | ![]() | Hold the swab parallel to the cornea and gently rub the conjunctiva in the lower eyelid. Place the swab inside the transport medium. See viral swabs |
| EAR- Bacterial | Charcoal Transport medium (wire shaft, orange top swab) | Antibiotics or other chemotherapeutic agents should not be used in the aural canal for three hours prior to the swab being taken. Place the swab in the outer ear and rotate the swab gently. Place the swab inside the transport medium. |
| NOSE- Bacterial | Charcoal Transport medium | Moisten the swab before hand with sterile saline. Move the swab from the anterior nares and direct it upwards into the tip of the nose and gently rotate gently. |
| THROAT-Bacterial | Charcoal Transport medium | Ask the patient to sit in a comfortable position and depress the tongue with a spatula. Avoid touching the mouth or tongue with the swab. Quickly, but gently, rub the swab over the appropriate area, usually the tonsillar fossa or the area with a lesion or visible exudate. NB: do not obtain throat samples if epiglottis is inflamed, as sampling may cause serious respiratory obstruction. |
| MOUTH-Bacterial | Charcoal Transport medium | Rub the swab over the appropriate area. Place the swab inside of the transport medium. |
| MOUTH - Viral | ![]() | Rub the swab over the appropriate area. Place the swab inside of the transport medium. See viral swabs |
| MRSA | Clear Transport Medium | See appropriate site for sample collection technique. |
| RECTAL- Bacterial | Charcoal Transport medium | Pass the swab, with care, through the anus into the rectum. |
| RECTAL - Viral | ![]() | Swab gently any ulcerated areas and place the swab inside the transport medium. See viral swabs |
| CHLAMYDIA | Sample collection pack | See Chlamydia |
| CERVIX- Bacterial | Charcoal Transport medium | Do not use lubricant during procedure. Wipe the cervix clean of vaginal secretions and mucous. Rotate a sterile swab, and obtain exudate from the endocervical glands. If no exudate is seen, insert a sterile swab (wire shaft - orange top) into the cervical canal and rotate the swab. |
| VAGINAL/CERVIX - Viral | ![]() | As above, placing the swab in viral transport medium. See viral swabs |
| VAGINA- Bacterial | Charcoal Transport medium | Use a speculum, without lubricant. Collect secretions from the mucosa high in the vaginal canal with swab. |
| VIRALSWABS |
Viral Transport medium | Swine Flu: See handout sheet Other Viruses: See viral swabs |
| URETHRA - Bacterial | Charcoal Transport medium (wire shaft, orange top swab) | Specialist sample taken by GU Clinic. |
| ULCER-Bacterial | Charcoal Transport medium | Remove overlying debris, curette the base of the ulcer. If exudate is present, sample with sterile swab. Place inside of the transport medium. |
| PENILE- Bacterial | Charcoal Transport medium | Retract the prepuce and rotate the swab gently around the urethral meatus. |
| PENILE - Viral | ![]() | Swab gently any ulcerated areas and place the swab inside the transport medium. See viral swabs |
| WHOOPING COUGH (Pertussis) | Swab technique withdrawn. Refer patient to the hospital paediatric team for Nasophargeal Aspriate | |
| WOUND-Bacterial | Charcoal Transport medium | Fluid or pus is preferable to swab collection. If the wound shows signs of clinical infection (heat, redness, swelling, discharge, etc.) this may indicate a deep-seated infection. In this case, the wound should be cleaned, or irrigated, with normal saline. Rotate the swab in the discharge present or the base of the wound to ensure good contact. |
