Direct Microscopic

Spore trap sampling involves collecting airborne particles on a filter membrane or adhesive-coated slide by drawing air through or over the collection medium, respectively.  The collection medium is then analyzed by transmitted light microscopy, usually at 600–1000× magnification.  A number of different collection devices may be used for spore trap sampling of which the most […]

Direct microscopy is considered the “gold standard” in environmental mycology for determining the existence of fungal growth on surfaces or materials. The direct observation of fungal spores, spore-bearing structures and mycelium provides an unequivocal marker of past or current growth. Direct microscopic examination of tape or bulk samples should first examine the specimen in reflected […]

This is an add-on test that provides further characterization of cultured bacterial contaminants according to Gram stain reaction and cell morphology. This test may be indicated when heterotrophic plate count (HPC) tests yield positive results. In this event, the laboratory will contact you and determine if you would like to add this level of characterization. […]
