The quality control in the laboratory department is normal but the patient results are high

1. Indoor quality control can only control the precision of the detection system.

That is, to control the stability of the usual inspection. The scope of quality control should be up to you to ensure the accuracy of the system.

Good premise statistical. This range control is used to maintain a steady state of the system. If the system is already "inaccurate" when the range is established, then the system that controls with this biased range is also inherently biased. The results of the patient will be high or low.

2. It is also not feasible to use the quality control target value and range given on the control product manual. Because this range is generally very lenient, even within this range does not guarantee reliable patient outcomes. At the same time, due to the matrix effect of the control itself.

The assignment is only appropriate for the equivalent system (instrument, reagent, calibrator, operation is identical). This kind of peer-to-peer system doesn't really exist. Therefore, all the quality control regulations state that the fixed value can only be used as a reference and cannot be used directly.

3. To make the instrument accurate in detecting patient samples, it is achieved by calibration. Calibrating your system with your system's calibration solution can theoretically enable your system to get accurate patient sample results. In order to verify the reliability of the calibration and the accuracy of the evaluation system, the method of participating in inter-laboratory quality evaluation is mostly used.

During the inspection: re-check the retained specimens; Before the test: interference with medication and so on.

The quality of the calibration results directly affects your results.

The method was to use a single concentration of undetermined serum, repeated the measurement 20 times in days and days, calculate the mean (x), standard deviation (s) and coefficient of variation (cv), draw the x-s quality control chart, and obtain the mean line (x), warning line (x 2s) and runaway line (x 3s). The control serum with the same batch number as the quality control chart was analyzed, and the result points were on the map, which was connected in a straight line.

Normal distribution rule: 95% of the data falls within x 2s; There cannot be 5 consecutive results on the same side; There can be no 5 ramps or falls; You can't fall 2 points in a row outside of x 2s; There should be no point that falls outside of x 3s.

Abnormal manifestations: Drift, suggesting systematic error; Trend changes, indicating that the performance of the reagent or instrument has changed; The change in accuracy indicates that the accidental error of the assay is large.

Take a batch of quality control for a certain item to do 20 times in a row, use the results of 20 times to find the average x, and the standard deviation s, and use the quality control in the daily work in the future, if the results are within x 3s, we will say that the detection status of a certain item today is ok, and we can do the patient's specimen, otherwise we have to consider whether there is a problem, including instrument reagents and so on. How to calculate the standard deviation, this can be calculated with the software on the computer.

In-house quality control can only control the precision of the inspection system. That is, to control the stability of the usual inspection. The scope of its quality control should be counted by itself on the premise of ensuring that the accuracy of the system is good.

This range control is used to maintain a steady state of the system. If the system is already "inaccurate" when the range is established, then the system that controls with this biased range is also inherently biased. The results of the patient will be high or low.

1. The number and rate of inspection projects carried out (with the Health and Family Planning Commission's "Medical Institutions.

Is it a biochemical laboratory, 1, you can jump the box on the top of the cargo box, but it must be fast, because the box will be broken with 1 shot! 2 Go to the billboard, (Bing disagrees, because there is no possibility of defense!) 3, a vacant room on the 2nd floor, can there be a large number of people there (people need to press CTRL + SPACE) on the 3rd floor, where you need to ensure that the glass matchmaker is there, then it is possible to hold it!

Otherwise, it will be in a state of 2-sided pinching.

Biochemical quality control charts are commonly used L-J quality control charts, Westgard quality control charts, efficacy function charts, etc. Each type of diagram has its own specific rules, you can follow my prompts to look up the Internet or flip through relevant books.

What does it mean, what is the medical test biochemical quality control chart???

What kind of quality control chart are you talking about?

Quality control limits, with upper and lower biases; Of course, there are cases where the one-way limit is also available.

Measurements may actually be skewed up or down compared to standard values, and upper and lower limits are naturally needed to limit the range.

Generally, there are 30 quality controls in a quality control chart a month, and one time exceeds 3s or two times exceeds 2s and it is out of control. 5 consecutive raises or decreases are also out of control.

There can be no two exceedances of 2s. More than 3s once is out of control. It cannot be raised or lowered 5 times in a row.

The term "clinical laboratory" in China generally refers to the results of a series of laboratory testing work and projects provided by clinical laboratories (i.e., laboratory departments, laboratories, or independent laboratories) for clinical medicine for the diagnosis of diseases. Quality control is the adoption of strict quality management measures to ensure the quality of inspection. The quality control before the analysis of clinical laboratory has an important impact on the accuracy of the test results, and the quality control of clinical laboratory ensures the accuracy and effectiveness of clinical testing.

Clinical testing should provide clinically valuable and accurate results so that clinicians can make a correct diagnosis of the patient's disease and provide relevant information for observing the efficacy, predicting the prognosis, and preventing the disease. At the same time, it is necessary to provide the necessary consultation for clinical practice, correctly interpret the test results and maximize the use of various information.

The clinical laboratory quality control center should control the relevant reports in a realistic manner, and make a series of strict regulations on the storage method and time of the relevant report forms to avoid related disputes. Therefore, in order to improve the quality level of clinical examination, it is necessary to do three things: for different specialties, we should strengthen the systematic training of relevant medical staff, enhance the ability of personnel to test knowledge, so that medical staff can fully understand and grasp the test results, and then greatly improve the quality of inspection and specimen collection.
