Health checkups and medical tests are essential components of preventive healthcare aimed at assessing an individual’s overall health status and detecting any potential medical conditions early. These evaluations involve a combination of physical examinations, laboratory tests, and screenings tailored to age, gender, and specific health risks.
During a health checkup, healthcare providers typically review medical history, conduct physical examinations to assess vital signs, and perform various tests based on individual health needs. Common medical tests include blood tests such as complete blood count (CBC), lipid profile, and metabolic panels to evaluate organ function, blood sugar levels, and cholesterol levels. Other tests may assess specific systems like thyroid function tests or screen for diseases like cancer through imaging studies or biopsies.
Regular health checkups not only help in early detection of diseases but also provide an opportunity for healthcare providers to offer guidance on healthy lifestyle choices, vaccination schedules, and disease prevention strategies. By staying proactive with health checkups, individuals can better manage their health and potentially prevent serious health complications.
Here are the detailed overview of the most common and important tests along with their descriptions and purposes.
