covid testing near home code example

Example 1: Covid test

simplistic/explanatory examples in another answer ("Bayes Covid")
*Sensitivity* impacts false negatives and *Specificity* impacts false positives
Sensitivity is 63% for a nasopharyngeal swab and 31% for a throat swab, meaning
a false sense of security can result from you "passing" your Covid test.
With little *precedence* we cant “rule out illness” given a negative test result.
(NPV) is LOW & the probability of being free of disease is UNDETERMINED.

Example 2: covid test

low pre-test probability (10–20%)...
	asymptomatic individuals in a presumed low prevalence environment 
moderate pre-test probability (40–60%)
	cough and fever in a city/jurisdiction with known cases
high pre-test probability (80–90%) 
	may include a patient with fever, cough, shortness of breath, 
	with a known close contact with confirmed COVID19.
