Which swabs can be used for diagnostic workflow and which to avoid?
Swabs compatibility
- Dry swabs, swabs within some aspirate collected at the same
site as the swab, or swabs in NaCl can be used.
- Swabs in a medium containing
agar can be difficult because the agar might lead to clogged columns.
- Commercially available systems need to be carefully
evaluated:
- The eNat® system for swabs (Copan, USA) cannot be used in
combination with any MolYsis™-based kits since it contains some detergent
initiating cell lysis.
- The eSwab® system for swabs (Copan, USA) can be used for
SepsiTest™-UMD but not for Micro-Dx™. The filtration steps on the column by
vacuum in the Micro-Dx™/SelectNA™plus are affected by the Amies medium included
in the eSwab® system which can lead to blocked columns and thus rejected
samples. SepsiTest™-UMD was not affected in tests with the eSwab® system.
