28
Q

examples of non statistical QC

A

daily temps
maintenance and troubleshooting on lab equipment
room temp and humidity

29
Q

statistical QC is

A

the use of specimen controls and QC charts to monitor the performance of analytical methods and assess the validity of patient test results

30
Q

statistical QC in the lab involves

A

running specimen controls with known values

31
Q

what is a control range

A

is the acceptable range of QC values that accounts for normal day to day variations

32
Q

acronym FIRED for troubleshooting the F stands for?

A

figure out what’s going on

33
Q

acronym FIRED for troubleshooting the I stands for?

A

isolate the cause

34
Q

acronym FIRED for troubleshooting the R stands for?

A

resolve the problem

35
Q

acronym FIRED for troubleshooting the D stands for?

A

document all steps and outcomes

36
Q

pre analytical

A

activities that take place from the time the lab tests are ordered to the time the specimens are processed and delivered to the testing laboratory

37
Q

analytical

A

activities involved in performing a test, verifying the reliability of the test results and interpreting the findings

38
Q

post analytical

A

activities involved in reporting and archiving results as well as retention of specimens

39
Q

QA

A

ensures that plans, policies and procedures across the entire path of specimen workflow are followed

40
Q

statistical WC control are samples with ** concentration of analytes and are carried through the *** run of the test procedure exactly like a patient sample

A

known, analytical

41
Q

matrix

A

a control should be the same matrix as the patient samples so that it behaves the same as a patient specimen in the test method

42
Q

lyophilized

A

freeze dried

43
Q

control range

A

the acceptable range of QC values that accounts for normal day-to-day variations

44
Q

confidence interval

A

the control range 95% of the time, it is also know and a 95% CI

45
Q

during hemolysis the plasma/serum will appear…

A

clear and red due to red cells being lysed and the release of hemoglobin into the fluid portion

46
Q

how does icteric happen

A

due to an increase in bilirubin in the blood which can be caused by increased destruction of red cells

47
Q

how does lipemic happen and can be cleared by?

A

due to the presence of fats or lipids suspended in the fluid portion of the blood
can be cleared by ultracentrifugation prior to testing
