How many kits do I need to test a house?

Each D4D PenTest kit contains an ampoule of reagent, instructions, and two test papers.

Each D4D kit contains 2 testing papers. It is recommended that one testing paper be used to take a sample, and the other used as a ‘control’ to compare results. Due to subtle variances in the test paper colour, this will ensure that any colour changes are quite obvious.

Depending on the size of the house 4 kits should be sufficient for a 3 or 4 bedroom house with garage.

  • 1 swab per bedroom
  • 1 swab per area for hallways, laundry, bathrooms
  • 1 swab per area for kitchen, dining room, lounge/dining room
  • 1 swab per area for the garage, workshop, garden shed

Samples should be taken from areas where contamination is most likely to remain after a basic clean-up has been carried out (see FAQ – What areas of a house are best to perform a surface test on?)
