Should I use Method 1 Visual Sampling or Method 2 Bulk Sampling to take mold samples?

Method 1 Visual Sampling is the recommended method and involves taking a sample of a visual mold growth. Method 2 Bulk Sampling allows you to take a sample of material (carpet, pad, tile, wood floor, etc.) and test for the presence and/or type of mold. It is $10.00 for each bulk sample sent and 3 bulk bags are included with this kit.
