Tuberculosis infections should be diagnosed quickly for the benefit of the patient and prevent the bacteria from spreading to other persons
New rapid blood test accurately diagnoses and rules out tuberculosis infection - health short science news

A new blood test has been developed that not only accurately diagnoses tuberculosis, but also rules out tuberculosis.

This means that patients who are tuberculosis-negative do not have to undergo unnecessary further screening, and that hospitals can refrain from doing additional tests to confirm the presence of the tuberculosis bacteria.

Thus, this test is better than the rapid blood test currently in use, which can detect, but cannot rule out tuberculosis, and will save health systems a lot of money.
