Swab testing by post

A self-taken surface swab kit, posted to our laboratory for microbial analysis.

When to use it

If you want to check a surface for microbial activity without arranging a site visit, a postal swab kit gives you laboratory analysis from a sample you take yourself, useful for a quick check between full surveys, or where a site visit isn’t practical.

How it works

  1. Order a kit: each kit includes a swab, sampling instructions, a chain of custody form and a pre-paid return envelope.
  2. Swab the surface: following the enclosed instructions to take the sample correctly.
  3. Post the sample: complete the chain of custody form and return it with the swab in the envelope provided.
  4. Receive your report: laboratory analysis is carried out on arrival and a written report issued.

What’s in the report

The report sets out what was found in your sample. For more complex issues (multiple locations, airborne sampling, or findings that need interpreting alongside a wider investigation), see our full range of laboratory tests, which may need an on-site visit rather than a postal kit.
