how to calculate radiographic sensitivity
as prevalence increases sensitivity and positive predictive value increases, negative predictive value and specificity decreases.
The answer is Yes, only if this is in reference to a selective and/or differential medium. Specificity is the ability of the test to identify negative results while sensitivity is the ability of a test to detect positive results. So, if taking out the NaCl effects your ability to interpret your data results then it in someway has effected your sensitivity and specificity.
Sensitivity in diagnostic laboratory testing represents the smallest amount of substance in a sample that can be accurately measured by an assay. Specificity in a diagnostic laboratory refers to the ability of an assay to measure one particular organism or substance.

The Matthew correlation coefficient considers true and false positives and negatives. The specificity correlation only considers the true classes or rejections.
i need an answer to this question to help me with my bio prac.... someone please answer this question!!!
1. sensitivity & irritability 2. conductivity 3. specificity 4. adaptability
Sensitivity measures how well a test identifies disease-positive (D+). Specificity measures the probability that a positive test result (T+) correlates to a real D+ person. These measures tend to be inverse of each other-- that is, the more sensitive a test, the less specific it is likely to be, and vice versa.
The false positive from the reaction of hydrogen peroxide and the inoculating loop would be caused by poor specificity. The formula for specificity is TN/TN+FP.
