It is important to collect samples as sterile as possible to avoid contamination with physiological and/or ubiquitous flora.

Swabs for bacteriology (aerobic and anaerobic microbes) and for mycology must be sent with a transport medium (swab in medium, TM) to protect the microbes during shipment.

Swabs for examinations using PCR should be sent without a transport medium (smear without medium (A), swab without medium, dry swab) or with a special medium.

Urine samples should be sent in a sterile tube using Uricult or using a swab with transport medium.

Hairs and/or skin scrapings for the diagnosis of dermatophytes are best sent in a paper bag or in aluminium.

For sending faeces/excrement, special transport tubes should be used, no bags or gloves tied with a knot; for birds, use cloacal swabs with transport medium.

Blood culture bottles can be ordered with prior written notice (subject to a charge).
