Part Descriptions

LP16849-9   Crystals
A crystal or crystalline solid is a material composed of atoms, molecules, or ions arranged in a spatial, orderly, repeating pattern. The scientific study of crystals and crystal formation is crystallography. The process of crystal formation is crystallization.

LP16849-9   Crystals
Crystals are formed in urine when solutes precipitate out of solution. Crystals are typically absent in freshly voided urine. Normally they precipitate as the urine cools or after it is refrigerated. Most crystals are not indicative of a pathological process, but when present in freshly voided urine, they indicate that crystals are forming within the body which is clinically important. When crystals develop within the nephrons, serious tubular damage is possible. Since the presence of some crystals in the urine are considered pathological, it is crucial that they be correctly identified and reported. Crystal identification is made based on microscopic physical appearance and urine pH.[Nancy A. Brunzel, Fundamentals of Urine & Body Fluid Analysis, p 189] Source: Regenstrief LOINC

LP7238-1   Body fld
The LOINC "Body fld" System represents body fluids other than serum, plasma, blood, urine, and cerebrospinal fluid. When a LOINC term with the System "Body fld" is used, the specific specimen source or body fluid type should be reported elsewhere with the result. Where more specific terms for pleural, peritoneal, synovial fluid, etc. exist, we encourage you to use the more specific terms. In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" is used for abnormal fluid collections that are aspirated, while "Body fld" is used for named body fluids, such as synovial fluid or peritoneal fluid, that are not inherently pathologic.
