As a common cause of pre-analysis error, how can sampling be performed without hemolysis?
A number of variables contribute to the achievement of high-quality non-hemolytic blood samples. Controlling blood flow between the tube and the blood vessels is the basis for obtaining a qualified sample. Factors that affect blood flow include: needle size, suction, thickness and quality of blood vessels, and the equipment used to collect blood. Blood is transfused directly into a vacuum blood collection tube, which controls the blood flow from the needle to the test tube. When blood is drawn into the syringe, the attraction should be minimized. The trick is to pull back the syringe and fill it with blood little by little, controlling blood flow in the process. This method is also suitable for injecting blood from the syringe into the collection tube.
How should a laboratory examine a sample to identify hemolysis?
A simple method is to inspect the serum visually and observe changes in the color of the serum.
Automated hemolysis index measurement on a biochemistry analyzer is a fast and reliable way to detect the presence or absence of hemolysis in a sample and quantify it correlatively. Compared with visual inspection, automated methods are more sensitive and reproducible in detecting the presence of hemolysis and in differentiating similar color interferences such as bilirubin. It is worth noting that the automated method allows for direct electronic communication with the laboratory information system.
How do I report hemolysis to my doctor?
Whether or not to report depends on the analyte and its hemolytic grade. Special care is required when choosing to cancel all hemolysis reports. If the pet has a history of hemolysis, more caution is required.
Many laboratories choose to report all samples, but with a description for severe hemolysis. Indicates that the sample has developed hemolysis and may mislead the laboratory results. Adding a qualifier to the hemolysis grade can help physicians determine how much it affects the outcome. However, any annotations attached need to be considered for their impact on the laboratory results shown in the test report. For physicians, it is critical that the area, annotations, and annotations on the report showing results are clearly visible.
Is it effective in improving the incidence of hemolysis?
Popularizing sampling knowledge to physicians and staff, standardizing the management of equipment and blood collection processes, clarifying clinical significance, and providing feedback from special units can reduce the incidence of hemolysis in hospitals by 50%. Therefore, it is necessary to raise the awareness that "good samples produce good results".
