FNR

The ratio of subjects affected by an illness whose test results wrongly suggest they are disease-free to all those subjects who have the disease. The false-negative ratio of a test is useful in determining the test's reliability (i.e., the higher the ratio, the less reliable the test).

A high FNR may be biological or analytical in origin. Biological false-negative test results may occur when a test is performed at the wrong stage of an illness (e.g., before an antibody or antigen is found in the blood). Analytical false negatives may result when a test lacks adequate sensitivity or specificity to detect an agent that is already present.

MAXIMUM CONTROL AND SAFETY The FNR control on the joystick, first seen on the new Bobcat TL470 and TL470HF 7 m telehandlers, ensures the operator has maximum control at their fingertips, allowing the driving direction to be selected at the touch of a button while still keeping a grip on both the steering wheel and the joystick for improved safety and productivity.
