A

State level, usually by the state health department

37
Q

when a test has a higher specificity than sensitivity:

A

a negative result will be more accurate than a positive.

A

CABG= about 5 hours
spinal fusion = about 4 hours
colon resection= about 3 hours
Ab hyst, hip prosthesis = about 2 hours

44

118 F for one hour

47
Q

outbreak and want to isolate as quickly as possible

A

use test with highest sensitivity
