Question 9 1 pts Tests for tuberculosis like all other diagnostic tests are not perfect. QFT-G is one of such tests for tuberculosis. Suppose that for the population of adults that is taking the test, 5% have tuberculosis. The test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time. Suppose that POS stands for the test gives a positive result and S means that the adult really has tuberculosis....

You are a research engineer working for a pharmaceutical company that is conducting clinical trials for a new disease screening test. Suppose that 2% of a clinic’s patients are known to have this disease. The test you developed is positive in 98% of the patients with the disease, but also positive in 3% of patients who do not have the disease. If a person who is chosen at random from the clinics patients is given the test and it comes out...

Lydia is concerned that she has strep throat, so she visits her doctor. Base on her initial examination, the doctor believes that there is a 70% chance that Lydia has strep throat. There is a test for strep throat known as the Rapid Strep Test (RST). If an individual has strep throat, the RST correctly identifies this 95% of the time (i.e. the true positive rate is 95%). If an individual does not have strep throat, the RST incorrectly identifies...

Consider a small town that has a population of 1,000 people. It is known that in this town, 10 people are infected with a rare disease. The remaining 990 people are NOT infected with the disease. This data is known with certainty. Recently, The FDA (Food and Drug administration) developed a test that determines if a person is infected with this disease. However, as with most test of this nature, it is not foolproof proof as there are a certain...

Topic: MALARIA Cause of Disease 1. What type of microbe causes the disease? 2. If it is a bacterium, what are the characteristics of the cell (Gram-negative or positive (what does that mean?), cell shape and arrangement? metabolic capabilities?). 3. If it is eukaryote, is it a fungus, an alga, a protozoan, a Platyhelminthes, or a nematode? Is it multicellular or unicellular? What is its life cycle? 4. If it is a virus, it must include the complete classification and...

A The patient was a 32-year-old Haitian male referred to the hospital with a 3-week history of fever, nausea, vomiting, and diarrhea. Four days after returning from Haiti, where he had participated at a funeral with unembalmed bodies, he developed a temperature of 39.50C, myalgias, constipation, and rectal pain. He was admitted to a hospital for an overnight stay and given LV. cefotaxime. He was discharged on oral cephalexin. His symptoms recurred 2 weeks later and his therapy was changed...

In the general population, only 0.3% have colorectal cancer. (Simply, interpret this as P(Cancer)=0.003.) The hemoccult test is used in the detection of colorectal cancer as a cheaper and much less invasive alternative to colonoscopy. However it is also much less accurate. The test is positive 50% of the time if the patient has the disease, and will be positive 3% of the time if the patient does not have the disease. What is the probability of a false negative...
