N: 1. “scientific discrimination,” especially in pathology, “the recognition of a disease from its symptoms,” 1680s, medical Latin application of Greek diagnōsis “a discerning, distinguishing,” from stem of diagignōskein “discern, distinguish,” literally “to know thoroughly” or “know apart (from another),” from dia “between” (see dia-) + gignōskein “to learn, to come to know,” from PIE root *gno– “to know.”
The earliest known use of the noun diagnosis is in the late 1600s. The Oxford English Dictionary (OED) earliest evidence for diagnosis is from 1681, in Table of Hard Words.
2. Determination of the nature of a disease or condition, or the distinguishing of one disease or condition from another. Assessment may be made through physical examination, laboratory tests, or the likes. Computerized programs may be used to enhance the decision-making process.
3. Diagnosis is defined as the process of recognising an injury, condition, or disease from the signs and symptoms the individual is displaying. Diagnostic tests are used to ascertain a diagnosis. Blood tests, health history, physical assessments, and other procedures may be used to help make a diagnosis. Diagnosing an illness is essential in mitigating complications that would arise if that condition goes undiagnosed and also for enhancing the efficiency of treatment regimes.
Diagnosis and prognosis are common words physicians use when treating an injury, condition or disease. They sound similar, but they refer to different parts of the medical process. Diagnosis is the process of identifying a medical issue, and prognosis is an evidence-based prediction of a person’s outcomes. Both require the healthcare team to gather evidence from sources such as patient reports, physical examinations and diagnostic tests.
