Automatic biochemical analyzer new reagents why should be calibrated? This is because in clinical testing, the operator may mix some biochemical analysis reagents with different lot numbers. Although this is convenient and can save costs. But no matter which instrument manufacturer and which reagent. Because of the different batch numbers and dates, there are bound to be differences, thus affecting the test results.
Firstly, it is because there is a difference in the activity of the instrumental enzymes in the reagents of the automatic biochemistry analyzer. Moreover, the concentration of the substrate that can produce hydrolysis will be different following the time. Therefore, instrument reagents mixed together and not calibrated can affect clinical test results, leading to inaccuracy and misleading doctors' judgment.
And if the reagents are opened for a long time there will be dust and bacteria seeping into the bottle. Some reagents have a large amount of protein and salt. This constitutes a more favorable environment for bacterial growth. Although some reagents have preservative ingredients. But there is a limit to the preservative's preservative function. In fact, most manufacturers' reagents do not contain preservatives.
Then what should be done?
1, The batch number of different testing reagents recommended not to mix together. If they must be mixed together, they must be calibrated.
2, Reagent bottles used in the instrument for too long will make the test results inaccurate. It is recommended to replace them within the specified time. Usually there are several ml of reagents left in the reagent bottle because the reagent needle is not completely sucked. If the reagent lot number is the same, there is no problem. If it is not the same, there will be a problem. The solution is to mix each remaining reagent in one piece. Calibrated and then tested.
3，It is recommended that if the test reagents are replaced, the new reagents should be calibrated and then put into daily testing.
These are the points that need to be reminded when using the reagents of automatic biochemistry analyzer. Just set the concentration of the corresponding calibration solution. Then place the standard solution in the designated position. Start running and you can get accurate test results.
Seamaty chemistry reagent trays are designed with microfluidic technology and precise internal independent channels to effectively avoid cross-contamination. This also ensures that reagent reactions are not interfered with by other substances. Moreover, the individual reagent trays are used together, which are free from cleaning and maintenance.
