Chapter 5 Q. C and Reference Value
The aim of Q.C. is to test
，
control the precision degree of the test; supervise the change of stability;
improve the conformity of sample test result about one group or between two groups in common test
work; it will assure the reliability of the test result for every patient sample.
You need to test Q.C. material in “TEST SAMPLE”, then print Q.C. curve and result in “Q.C.
REPORT”. “Q.C. REPORT” menu:
5.1 Preparation
1.1
Select Q.C. material:
The Q.C. material dry powder produced by professional supplier;
1.2
Prepare Q.C. material:
Dilute the Q.C. dry powder according to the manual, lay it aside for 20 minutes, use it after it
becomes stable.
5.2 Test Q.C. material
2.1
Press ‘2’ to enter “TEST SAMPLE” submenu in main menu, input the item No. of the Q.C.
item(For example: if the item is GPT, input ‘1’), press ‘ENTER’ to assure. It will suggest “ABSORB
SAMPLE LIQUOR” after absorbing the clean water, then press ‘7’ to setting the patient No., such as
59000(It’s better to setting it as 59XXX to avoid to confuse it with normal patients; please remember
the No. because it will be used in the follow procedures), then test the prepared Q.C. material
according to the method of testing sample.
2.2
Enter “RESULT REPORT” submenu after finishing testing, press ‘1’ to enter “EDIT PATIENT
INFORMATION”, select the Q.C. patient No., such as 59000, Input the item name (For example: GPT)
in “NAME” to check and print. Press ‘menu’ to quit, it is the whole test procedure of Q.C..
2.3
Later, you only need to operate the first step to test the item’s Q.C. result, Be care that the item
No. and patient No. should be the same to the setting of the first time test completely. Enter “Q.C.
REPORT” submenu to print the curve and result when there are more than 5 test results of the
patient.
5.3 Print the curve and result of Q.C.
3.1 Enter “Q.C. REPORT”, select the item No. of the Q.C. in the operation ‘1—SELECT Q.C. ITEM’
and setting the target value. You can evaluate or consult other materials.
3.2 Select the corresponding patient No. such as 59000 in the operation ‘2- SELECT Q.C. No.’
3.3 Carry out the Operation ‘3’.‘4’to print the Q.C. curve and result (Including MEAN and SD) after
carrying out operation ‘1’.‘2’.
3.4 When you test and print the Q.C. curve and result later, you should define the target value
1-SELECT Q.C. TEST
2-SELECT Q.C. No.
3-PRINT Q.C. CURVE
4-PRINT Q.C. RESULT
