STDs – For those who are sexually active, especially where there is more than one sexual partner, screenings for STDs are highly recommended. While every test strives for the highest achievable accuracy and specificity, there is no such thing as a perfect test or battery of tests. A battery of tests, no matter how extensive, can never be exhaustive enough to capture all the things at once, says Dr Ng. That means, a radiological test that exposes a person to radiation must be done with a justifiable reason , after considering other tests that can achieve the same goals with less radiation or cost. They were speaking about the considerations that should be included before the rollout of a national screening programme, but the principles apply to individual cases as well.

Many diseases and medical problems can’t be diagnosed with blood tests alone. However, blood tests can help you and your doctor learn more about your health. Blood tests also can help find potential problems early, when treatments or lifestyle changes may work best. Doctors can’t diagnose many diseases and medical problems with blood tests alone.

Neither her LDL cholesterol nor her C-reactive protein was elevated. Perhaps, that would depend on which of these stories about the benefits and pitfalls of screening you believe the most.

For such rare diseases, a large proportion of those with positive screening tests will inevitably be found not to have the disease upon further diagnostic testing. For example, mammograms are recommended for women over the age of forty, because that is a population with a higher prevalence of breast cancer.

As we get older, we have a higher risk of developing one of these conditions. When the prevalence of preclinical disease is low, the positive predictive value will also be low, even using a test with high sensitivity and specificity.

However, when these factors are excluded, follow-up actions on abnormal results are critically important to ensure speedy diagnosis and treatment of the underlying disorders. Sometimes, blood test results are affected by specific foods, the drugs a patient is taking, and the patient’s compliance to pre-test instructions. For example, says Dr Ng, a smoker tends to have a slightly raised white cell count, and hence, this should not raise any alarm.
