FAQs

Biochemical analyzer, also known as biochemical analyzer, is an instrument that uses photoelectric colorimetric principle to measure certain chemical components in body fluid. Because of its fast measurement speed, high accuracy and small reagent consumption, it has been widely used in hospitals at all levels, epidemic prevention stations and family planning service stations. Combined use can greatly improve the efficiency and income of routine biochemical test.

What is calibration? Will everything be all right with the bid?

1. Significance of calibration

Calibration is to find a reference point, which is a k value (or F value). It is determined by the state of instrument and reagent. When we measure a sample, whether you use manual method or automatic biochemical analyzer, the measured value is just an absorbance, which has no significance for us. We need to convert the absorbance into a concentration or enzyme activity. That’s multiplied by a k value, and the calculated and printed results are meaningful to us. K is what we find by scaling. Generally, the minimum requirement is to have a reagent blank and a standard sample, and two absorbances can be determined by the instrument

K = (standard concentration – reagent blank) / (a standard – reagent blank)

(reagent blank is usually 0)

We know the concentration of the standard solution. These two absorbances can be measured by the instrument, so we can get a k value. No matter what kind of specimen, we can get the answer by multiplying its absorbance by K value. Therefore, K value has a very decisive significance, which can determine the accuracy of specimens.

2. The determinants of K value

Let’s see what happens to the K value? First, the concentration of the standard solution must be accurate (the standard solution should be based on serum as the sample). Second, the absorbance of the standard solution and the reagent blank must be accurate. The absorbance is affected by the condition of instrument and reagent. If your instrument is quite stable, the reagent is a major factor affecting the K value.

3. How to determine the value of K is correct?

We generally use quality control serum to check, and it is better to use two levels of quality control serum to check. If the quality control result is good, it can be said that the K value is accurate. Using this k value to calculate the patient’s result is also accurate, so the K value is very important.

4. The true face of K value

The K value actually represents the slope, and the intercept represents the reagent blank. The reagent blank changes every day, so the stability of the K value determines your instrument and reagent. If the instrument and reagent are stable, the K value is also stable.

5. How often is it appropriate to make a calibration?

It depends on the stability of your reagent. The quality control results are not good. Some items can be solved by reagent blank, and some items need to be calibrated by two points.

6. Is daily calibration enough to ensure stable results?

Not necessarily. Maybe you don’t dissolve the calibration solution every day, because there are some unstable items after the re dissolution of the calibration solution, such as TBIL, DBIL (visible light decomposition), Glu (bacterial decomposition) and enzyme items (re dissolution and degradation after freezing). Solution: during the calibration of the above items, a new bottle of calibration solution must be dissolved for at least 30 minutes, and the determination shall be completed within 1 hour

Before quality control and sample test, pay attention to the following points:

1、 Whether the positions of reagent probe, sample probe, stirring rod and cleaning arm are correct, especially the position of reaction cup, such as

Adding reagent or sample to the wall of reaction cup will affect the test;

2、 Whether all the reaction cups are clean, whether there is residual water in the cup, whether there is water on the outer wall of the reaction cup, and whether there is water in the reaction tank

Water, if there is water, please wipe it clean;

3、 Carry out the cleaning procedure, observe whether the water in the cup will overflow when the 7-Stage cleaning arm cleans the reaction cup, 7 cleaning needles

Whether the tip of the needle will drip down.

Quality control test:

Click quality control solution setting, click add, input name: quality control solution, batch number: 852un, concentration level: medium, sample

Disk number: 1 sample disk, virtual number: 0, sample cup number: 58, then select all items and click on the lower right corner respectively

Enter the target value and standard deviation of the item in the white box of the average concentration, and then select an item and enter its target value and standard deviation

Standard deviation (the target value and standard deviation of all items are set according to the target value table in the manual) is shown in the attached table:

2、 Input the target value and standard deviation of all the items to be controlled in turn, and then click save,

Check all target values and concentrations for errors. If there are errors, click Modify, and then save;

Page 1

3、 Then click quality control application, select the number of the quality control solution you just added, and then click the small positive corresponding to the number

Square, a small tick will appear, all items on the right will be selected by default (green dot means selected), confirm

After there is no missing item, click start test, it will automatically jump to the sample detection interface and click start test

Before the start of the test, pay attention to remove all the reagent covers and use samples for quality control solution

The cup is in the set position;

4、 After the test, click the quality control result, click query, and observe whether the test value is in the positive and negative standard deviation of the target value

If not, please check whether the quality control solution, calibration and reagent are normal, and whether there is any problem in the process of machine test

Abnormal phenomena;

5、 If there is no abnormality, adjust K factor, formula: new K factor = (mean value) ÷ Test value) x is the K factor calibrated by X;

6、 The calibrated K-factor is viewed in the calibration result. First, find the factor in the calibration result, such as “K” in urea

The value is 0.0086, and then 0.0086 times 10000 equal dry 86, 86 is the real K factor to be converted;

7、 After getting the new K-factor, find the item urea in the calibration settings, and modify the calibration rules to K-factor method

Enter the new K factor and click save;

8、 Repeat the quality control test and observe the quality control results.
