specificity
High false positive cases signify that disease has
high incidence & low prevalence
False negative means
person has disease but shows negative test result
High false positive in a test is due to
high sensitivity
Positive predict value of a test depends upon
prevalence of disease
AD syringes?
Auto Disabled syringes
specialized
plastic syringes introduced in UIP for administering
injectable vaccines. Once used, these syringes
get locked. This avoids reuse or misuse of used
syringes and ensures prevention of transmission
of infections from one child or pregnant woman
to another.
