1(2s) Correct Answers outside of +/- 2SD
warning rule
1(3s) Correct Answers outside of +/- 3SD
reject: random error
2 hour post prandial test Correct Answers -Patient is given a 75
gram dose of glucose.
-Two hours later, blood is drawn.
-If the level is > 200 mg/dL, and is confirmed on another day,
the patient is diagnosed with Diabetes Mellitus.
-less than 140 is considered normal
2 step glucose tolerance Correct Answers step 1
-50 g Glucose Load is given
-If > 140 mg/dL after one hour then proceed to Step 2
step 2
-100 g Glucose Load
-3 hour OGTT
,-Gestational Diabetes if: Fasting: >92 mg/dL , 1 Hour: > 180
mg/dL , 2 Hour: > 153 mg/dL , 3 Hour: > 140 mg/dL
2(2s) Correct Answers outside of +/- 2SD two days in a row
reject: systematic error
4(1s) Correct Answers four consecutive controls exceed the true
mean by +/- 1SD
reject: systematic
A shift is a change in ____, therefore it is a ______ error Correct
Answers accuracy, systematic
A trend is a change in ____ and therefore a ______ error Correct
Answers accuracy, systematic error

(branches)
amylose Correct Answers only alpha 1,4 linkage (spiral shape)
An outlier is a change in _____, and therefore a ____ error
Correct Answers precision, random
Analytical variation Correct Answers -Calibration,
documentation of protocol and procedure, monitoring equipment
and materials, preparation and storage of reagents, lot to lot
