How do mold test kits work?

Mold testing allows you to collect samples – from the air or surfaces – and provides you with an agent to grow mold or instructions for sending the samples for lab analysis.

With most kits, you will see visible mold growth within 48 hours if the sample you collect contains mold spores. Most kits also have a mail-in lab option, which allows you to send your collection to a lab for detailed analysis of mold and mold spore count types. Some mail-in tests include the fee in the purchase price, while others charge an additional $30-$40 for the test.

The four main types of mold test kits include air pumps, swab tests, tape strips, and petri dishes.

  • Air pump mold test kit Works by collecting air particles from the room. Users must send samples to the lab after collection.
  • Swab test Ideal for testing mold on surfaces such as HVAC units, window air conditioners, walls and areas with visible mold. After swabbing the area, users must send the sample to a lab or grow it in a petri dish.
  • petri dish Allows you to test for mold at home without sending you to a lab. These foods encourage mold growth, so if mold spores from the air hit the Petri dish, you should be able to see visible mold within 48 hours. Testers can send petri dishes to a lab for further analysis.
  • Tape test Lab analysis is one type of DIY mold kit. Testers place the tape with the sticky side to the test site and then package and mail the strip.
