CHAPTER 3 MEASURING PRINCIPLE

3.1 Principle

Lambert’s Beer Law:

When a parallel monochrome light beam goes through a light-absorbing object (gas, liquid
or solid), some photons are absorbed and the light intensity decreases from I0 to I, the
formula is:

I
− lg = εLC
I0

ε: Proportionality factor
I: Intensity of shoot-out light
I0: Intensity of shoot-in light
Measure I, I0, and L, and then calculate the concentration C according to the formula
above.

3.2 Assay Methods

3.2.1 Endpoint Assay

Endpoint assay means the concentration of measured item is calculated according to the
absorbance at the end of the reaction process.

1-point of Endpoint Assay

Endpoint assay in which absorbance is measured at a time point when absorbance stops
changing at the end of the reaction process. The reaction curve below explains the assay.

Formula: Concentration= (calculated absorbance - absorbance of reagent blank) ×K

[K is the absorbance coefficient i.e., Standard factor]

19
 URIT-8031 Operating Manual

Figure 3.2.1-1 1-point of Endpoint Assay

2-point of Endpoint Assay

End-point assay in which measurement is made twice at different points(at the beginning
and at the end of the reaction time) to obtain the difference of absorbance. Observe the
reaction curve below.

Formula: Concentration= (Absorbance 2 - Absorbance 1) ×K

[K is the absorbance coefficient i.e. standard factor]

Figure 3.2.1-2 2-point of Endpoint Assay

3.2.2 Two-point Assay

Measurement is made twice at two different optional points (except the start point and end
point of the reaction time) to obtain the difference of absorbance. Observe the reaction
curve below.

The formula is the same as 2-point of endpoint assay.

This assay is helpful to solute some non-specificity problem in some of the reaction.

20
 URIT-8031 Operating Manual

CHAPTER 6 QUALITY CONTROL ANALYSES AND

CALIBRATION

6.1 General Information

The reliability of test result is determined by two aspects: One is the precision, which
means test results are stable in repeatability. Precision can be guaranteed by establishing
perfect room quality control system; the other one is accuracy, which means test results
close to target value. Accuracy can be guaranteed by proper assay and calibration. It is,
therefore, necessary to select certified control sample and calibration solution, and use
them strictly according to their instructions.

6.2 Quality Control

6.2.1 Type of Quality Control Materials

1) Freeze-dry control, liquid control and mixed control serum, classified according to
physical property.

2) Fixed value and non-fixed value control sample, classified according to the presence
and absence of fixed value. Different inspection body can choose more than one
quality control as quality control.

42
 URIT-8031 Operating Manual

6.2.2 Use and Storage

1) Strictly following the instruction of quality control to operate.

2) Make sure the quality of control solution when redissolved from freeze-dry control
sample is stable.
3) Make sure the dilution ratio is accurate and consistent each time redissolving
freeze-dry control sample.
4) DO NOT shake control sample fiercely when redissolving freeze-dry control sample.
5) Store control sample according to requirement. DO NOT use expired product.
6) Perform QC analyses under the same operating conditions as that of sample
analyses.

6.2.3 Setup of Target Value, SD and Control Limit

QC target value and control limit are usually provided by the control samples supplier, also,
you can determine them through the following methods:

1) Setup of interim target value (mean value) and SD

Perform QC analyses at least 20 times with a new batch of control sample. Calculate
the mean value and standard deviation from the obtained QC data.

2) Setup of regular target value (mean value) and SD

Obtain the accumulated mean value of original 20 QC data as the target value while
the accumulated mean value of 3~5 month QC data as the standard deviation.

3) Setup of control limit

Control limit is the multiplier of standard deviation. Control limit of analytical item is
determined according to different QC rules.

6.2.4 QC Procedures

QC procedure consists of two systems; they are “Chemistry QC Management” and “QC
Analyses”. Select “Chemistry QC Management” in the “Chemistry Analyses”, its function is
setup the parameter before QC Analyses and process the QC data, such as setup the QC
target value, QC batch number and SD value etc. Select “QC Analyses” in “Special
Analyses” to begin QC Analyses, QC data will saved in system automatically and a QC
diagram will generate for chemistry analyses; QC Analyses could be add to routine test
interface. See 4.2.5 for application of QC Analyses.

 URIT-8031 Operating Manual

6.3.3 Reasons of Random Error

Below are the possible reasons of random error.

1) Inaccurate dispensing volume (sample, reagent)

Aspirating mechanism is leakage; air bubbles in flow path; contaminated probe;
deflective injection of reagent, etc.

2) Optical system failure

Lamp is faulty.

3) Metamorphic Reagent
Metamorphic Reagent

4) Adverse quality-control samples

Use of wrong control sample;

5) Inadequate wash
Stirrer wash is inadequate.

6) Adverse mixture
The depth of stirrer to cuvette is excursion; stirrer mechanism faulty.

6.3.4 Reason of Systematic Error

1) Inaccurate standard
The dissolvent of standard solution is inappropriate

2) Metamorphic reagent
The reagent is metamorphic, and the batch number is various.

3) Temperature
The temperature control is inappropriate.

6.4 How to Deal With Out-of-Control

1) Fill in Out-of-Control report and report to your lab supervisor.

2) Simply and quickly review the operating procedure to find out the possible reasons.
3) If no evident error is found, move to the following steps for further checkup.

 Retest the out-of-control item by using the same bottle of control sample. Strictly obey
the operation flow to check if the out-of-control is due to operation incorrectly or
random error. If retest result falls outside the acceptable range, proceed to the next
step.

 Retest the out-of-control item by using a new bottle of control sample (same lot). If
retest result is in control, the previous bottle of control sample may be to blame. If

47
 URIT-8031 Operating Manual

retest result still falls outside the allowable range, proceed to the next step.

 Retest the out-of-control item by using a new lot of control sample. If retest result is in
control, the previous lot of control sample may be deteriorated. Then check the
expiration date and storage condition. If retest result still falls outside the allowable
range, proceed to the next step.

 Perform instrument maintenance; retest the out-of-control item. Check the instrument
state; check whether the light source or filter are changed or not; and whether the
cuvette need to wash or replaced. Furthermore, replacing reagent. If the retest result
still falls outside range, proceed to the next step.

 Recalibration and retest out-of-control item. Perform calibration by using new

calibrating solution. Proceed to the next step if the result still falls outside range.

 Obtain technical help. If you cannot get the in-control result after performing the above
five steps, contact reagent manufacturer or URIT to get more technical support.

6.5 Calibration and Procedures

Calibration solution contains the known quantity object, which is used for calibrating the
value of this method; the calibration solution is concerned with the method, reagent and
instrument. The function of calibration solution is to reduce or eliminate systematic error
caused by instrument and reagent. It should be better to use human serum matrix to
reduce matrix effect.

6.5.1 When to calibrate

It is suggested to perform calibration every six months or under the following situations:

 When initially installing and running the instrument.

 When changing reagent batch number or type, unless specified by the lab that the
change will not influence the precision.

 After replacing the major components, such as lamp, sampling mechanism, probe, or
cuvette etc.

 After performing a preventive maintenance on the instrument.

 When control result shows abnormal offset, tendency, or falls out of the acceptable
range and it cannot be corrected by routine tests.

6.5.2 Calibrate Procedures

There are two ways to carry out calibration:

1) Applying standard analyses in “Special Analyses”

Select “Special Analyses” to applying standard analyses for each item, analytical data

48
 URIT-8031 Operating Manual

will save in system automatically and for analyzing.

2) Select the item which need to be calibrated in “Routine Item Parameter”

Input and save the concentration value of calibration material into the standard column.

Enter “Routine Analyses” interface, if “Concentration of Standard Material” has been input
when setup the parameter of analytical item, the selection of this item will appear in the
“Standard list”.

Select the item in the “Standard” list for standard analyses. Analytical result will be
processed and saved automatically and to be the standard of this item (standard factor).

NOTE
See 4.2.5 for standard application and test.

NOTE
System default the value of “Standard Factor” as 1 when newly built an item; and
system will calculate the result according to the standard factor “1” if not
modified.

NOTE
It is suggested that all calibration work should be written down and complied into
documents. What should be emphasized is that the fixed-value control serum
should never be used as standard solution.

NOTE
The calibration cycle could be set manually or automatically.
