1. basal state When the patient has fasted and not excersiced in 8-12 hours
2. when are inpatient in the morning when they are more liek;y to be in their basal state
specimens mostly
collected?
3. uncontrollable -age
pateint variables -alcohol consumption will affect certain tests (liver enzymes)
-altitude (more RBC)
-dehydration (hemoconcentration)
-diurnal variation
-exercise (increase i nsome analaytes)
-fasting
-pateint sex
4. stat 1 hour for test results
5. urgent 3-4 hours for results
6. routine 24 hours for results
7. timed collection at certain time
8. times results are monitoring drug levels
ususally used for?
9. how are specimens in a ¡leak-resistant bag with a zip closure, marked with a biohazard symbol,
transported? and with a separate front pouch for requisitions to prevent contamination in
case of a leak

11. uncentrifuged 45 minutes of being drawn
blood should be
delivered to the lab
within?
12. CLSI states that 2 hours
no more than
_____________ should
pass b/t collection
and centrifugation
13. why must samples Certain analytes have a shorter stability
be run or separated
within a certain time
frame
14. how do you keep Samples may need to be warmed in a 37°C dry heat block or water bath before
speciemens warm? testing, which would be taken care of within the department
15. most tests are stable 8 hours
at room temp for?
(after separation
16. why would you need Chilling a specimen slows metabolic processes and keeps analytes stable
to keep a specimen during transport and handling (pyruvate, ammonia, lactic acid)
cool?
17. why would you sending the specimen to other testing sites (transport on dry ice) or for
freeze a specimen? batched testing that takes place on certain days of the week
(-20 to -70°C)
