as prevalence increases sensitivity and positive predictive value increases, negative predictive value and specificity decreases.
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!!!
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.
Omitting NaCl would alter the osmolarity and ion content of the medium, which could affect the growth and survival of certain organisms. This could impact the medium's specificity and sensitivity by limiting the ability of some organisms to grow or inhibiting the growth of others. It's important to consider the nutritional requirements of the target organisms when omitting components from a medium.
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.
