The endocrine system is evaluated primarily
by measuring hormone concentrations.
Only order tests that will influence patient
management and outcome.
An understanding of hormone secretion,

essential when doing hormone testing.

SENSITIVITY: percentage of individuals
with disease who have a positive test result
SPECIFICITY: percentage of individuals
without disease who have a negative test
result
PREVALENCE: ratio of number of
individuals with disease to number of
individuals in population to be tested
