A "specimen" refers to an individual example or sample of a larger group, often used for study or analysis. In scientific contexts, specimens can include plants, animals, or minerals collected for research purposes. They help scientists understand the characteristics and behaviors of various species or materials. In medicine, a specimen may refer to a sample of bodily fluid, tissue, or cells taken for diagnostic testing. This can include blood, urine, or biopsies, which are analyzed to detect diseases or monitor health conditions. Proper handling and labeling of specimens are crucial for accurate results.
