Another way of pricing the food consumed is to use the number and color of the dishes left on the patron's table as a guide, similar to the method used in some Japanese conveyor belt sushi restaurants. Some newer restaurants offer a conveyor belt dim sum format, similar to the conveyor belt sushi eating places.
Sensitivity refers to a test's ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed. The specificity of a test is its ability to designate an individual who does not have a disease as negative. A highly specific test means that there are few false positive results.
Sensitivity is the ability of a test to correctly identify individuals who have a given disease or condition. For example, a certain test may have proven to be 90% sensitive. If 100 people are known to have a certain disease, the test that identifies that disease will correctly do so for 90 of those 100 cases (90%).The other 10 people (10%) tested will not show the expected result for this test.For that 10%, the finding of a normal result can be misleading and is termed false-negative.he accuracy and precision of each test method are established and are frequently monitored by the professional laboratory personnel. Sensitivity and specificity data are determined by research studies and are generally found in medical literature.
