In the context of laboratory results, the abbreviation typically refers to total nucleated particles. This count represents the total number of cells containing a nucleus within a specific sample, such as blood or bodily fluid. For example, a complete blood count often includes this measurement to assess overall cellularity. Differentiation between various nucleated cell types, like white blood cells, is usually performed separately.
Quantifying these particles provides valuable diagnostic information for a range of medical conditions. It can help identify infections, inflammation, and bone marrow disorders. Historically, manual counting methods were used, but automated analyzers now offer greater speed and precision. This advancement allows for faster diagnoses and more effective patient management.
