Band Cells: Band cells are a type of white blood cell. Band cells are the immature form of neutrophils and are produced rapidly during an infection. A large percentage of band cells in a venous blood sample indicate an infectious process occurring in the body.
Sensitivity and specificity. Sensitivity and specificity are concepts used to assess a clinical test. Sensitivity is a measure that determines the ability of a test to correctly classify an individual as sick or diseased. Specificity is a measure of the ability of a test to correctly classify an individual as healthy or disease-free. Parikh and others reckons that sensitivity and specificity are inversely proportional, which means that as the value of sensitivity increases, the value of specificity decreases and vice versa.
Precision delivers a ratio of positive results to the false positive results whereas sensitivity is a measure of the ratio of actual positives to the total of positives the test measured, including the indirectly counted ones. Specificity. Specificity is also known as true negative rate.
