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.
Specificity Refers to the ability of the test to detect reactions between homologous antigens and antibodies only, and with no other In a highly specific test, false positive reactions are absent or minimal In general, sensitivity and specificity of a test are in inverse proportion.
