This category of test includes the viewing of spores collected on tape slides, swabs and bulk. We typically will view a 1 cm2 area on a tape. Swabs are rubbed onto a tape to view the contents. Bulk samples are viewed at low power (20-60x ) to determine areas that might contain spores or fungal growth.
Then a tape sample is analyzed with the compound microscope at higher powers to identify the spore types.
