02 Sep Why Is Health Screening Important?
Locating Effective Solutions For Healthcare
If prevalence of the condition or disease is low, screening will not identify many cases, rendering the test less cost-effective. In addition to cost considerations, some tests are not without risks of their own or discomfort. To justify administering these tests to the population, the potential harm to the patient if the disease is not diagnosed must outweigh the distress or pain of the test. Pseudodisease is a condition detected by screening that does not require treatment because it will not adversely affect the patient’s life.
The primary purpose of screening tests is to detect early disease or risk factors for disease in large numbers of apparently healthy individuals. To justify their cost, screening tests must be able to detect a high number of cases of preclinical disease in the screened population.

Type I pseudodisease refers to conditions that might not progress to symptomatic disease and may even regress. Type II pseudodisease is an indolent, slowly progressive disease found in conditions with a long detectable preclinical phase.

- Anemia has many causes, including low levels of certain vitamins or iron, blood loss, or an underlying condition.
- If your platelet count is outside the normal range, you’ll likely need additional tests to diagnose the cause.
- A platelet count that’s lower than normal or higher than normal is often a sign of an underlying medical condition, or it may be a side effect from medication.
Controversy arises from the use of full-body scans in the screening of patients who have no signs or symptoms suggestive of a disease. As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage. A red blood cell count that’s higher than normal , or high hemoglobin or hematocrit levels, could point to an underlying medical condition, such as polycythemia vera or heart disease. Of if you’re undergoing cancer treatment, the results of a complete blood count outside the normal range may indicate a need to alter your treatment plan. Your doctor may suggest a complete blood count if you’re experiencing weakness, fatigue, fever, inflammation, bruising or bleeding.
If pseudodisease conditions such as cancers are treated std symptoms, the patient may be considered “cured” because he or she died from a cause other than cancer. But designating such outcomes as “cures” is erroneous because the cancer—even ifuntreated—would not have killed the patient before the time that he or she actually died of other causes.
A complete blood count may help diagnose the cause of these signs and symptoms. If your doctor suspects you have an infection, the test can also help confirm that diagnosis. A number of blood tests can be carried out to help diagnose certain cancers or check if you’re at an increased risk of developing a particular type of cancer.
Other common tests include x-rays, blood tests, fecalysis and urinalysis. Health screening is an effective way to detect a specific disease or condition early, even when there have been no symptoms or signs of the disease. Detecting a condition early means getting the right treatment at the right time and this gives patients better control over their health. A full-body scan has the potential to identify disease (e.g. cancer) in early stages, and early identification can improve the success of curative efforts.
