| Mucous Threads Mucous threads are semi-transparent under brightfield microscopy and could be mistaken for hyaline casts. They occur as ribbon-like strands with poorly defined edges, pointed or split ends and longitudinal striations. | View Page |
| Starch Granules Some starch granules from dusting powders have faint concentric striations, others do not. External contaminants (ie. those that enter the urine specimen during collection, transportation, or while being examined on the slide) must be differentiated from crystals and other clinically significant findings. | View Page |
| Coverslip Scratches Dark markings and striations may originate from the coverslip. | View Page |
| Mucous Threads Under Phase Contrast Under phase contrast, mucous threads appear much darker. Longitudinal striations and pointed ends are easily visible. | View Page |
| Contaminants and Artifacts There are several contaminants and artifacts which must be identified. This slide shows a fiber. Fibers may occur in any specimen from clothing, diapers, lint, toilet paper or lens paper. They are usually longer and wider than casts and have more distinct edges. Striation and blunt ends are distinguishing features of fibers. | View Page |
