Part Description
LP16857-2 Hyaline casts
The most common type of casts, hyaline casts are solidified Tamm-Horsfall mucoproteins secreted from the tubular epithelial cells of individual nephrons. Low urine flow, concentrated urine, or an acidic environment can contribute to the formation of hyaline casts, and, as such, they may be seen in normal individuals in dehydration or vigorous exercise. Hyaline casts are cylindrical and clear, with a low refractive index, so that they can easily be missed on cursory review under brightfield microscopy, or in an aged sample where dissolution has occurred. On the other hand, phase contrast microscopy leads to easier identification. Given the ubiquitous presence of Tamm-Horsfall protein, other cast types are formed via the inclusion or adhesion of other elements to the hyaline base.
