Diagnostic refers to the process of identifying a disease or condition based on symptoms, signs, medical history, and various tests or examinations. In healthcare, diagnostic procedures are crucial for determining the underlying cause of a patient's health issues. This can involve laboratory tests (like blood work or urine analysis), imaging techniques (such as X-rays, CT scans, or MRIs), and physical examinations. Accurate diagnosis helps guide treatment plans, ensuring that patients receive the appropriate care. Diagnostic tools and technology continue to evolve, enabling healthcare providers to detect and treat conditions more effectively and early in their progression.
