People are not unfamiliar with blood routine tests. When people go to the hospital for treatment, doctors often issue a blood routine test form. As the most general and fundamental blood test, it can effectively reflect the hematopoietic status of the body and provide important reference for disease diagnosis. However, in blood routine tests, there are many items included. The up and down arrows in the report often make people feel nervous, and people often have no idea what the numerical expressions of various projects mean. We will take you into the blood routine examination and learn about the things related to blood routine examination!
1、 The role of blood routine test
Through blood routine test, it can clarify the blood condition of the human body, help doctors clarify the diagnosis and treatment direction of diseases, and optimize the treatment effect of diseases. When the cause of the patient's illness is unknown, sensitive indicators in blood routine examination can often better reflect the pathological changes in the patient's body, improve diagnosis and treatment efficiency, ensure the scientific and effective diagnosis and treatment plan, and be fully responsible for the quality of clinical medical care and the safety of patients' lives.
2、 Common indicators in blood routine test
In the blood routine test report, there are more than 20 test results displayed. Among them, red blood cell count mainly reflects the number of red blood cells in the patient's blood. If the count of this item is too high, it indicates that the patient may have symptoms such as congenital heart disease and pulmonary heart disease, while patients with anemia, leukemia and other diseases often have low red blood cell counts. Abnormal white blood cell count is related to various diseases and the body's ability to resist pathogenic microorganisms. Patients with inflammatory diseases, postoperative conditions, and uremia often have high white blood cell counts, and when the count of this indicator decreases, it reflects that the patient may have symptoms such as viral infection and typhoid fever. Regarding platelet count, if it is lower than the normal value, it indicates that the patient may have coagulation disorders, immune thrombocytopenia, and other conditions. When the test value is high, it is necessary to consider whether the patient has purulent infection, myeloproliferative diseases, etc.
3、 Blood collection methods and precautions for routine blood tests
During routine blood tests, blood samples can be obtained through two methods: venous blood collection and fingertip blood collection. The pain of venous blood collection is relatively low, and it is often more precise, with a higher frequency of use in clinical practice. The accuracy of test results is closely related to the storage time of blood samples. If the sample storage time is too long, it will greatly affect the accuracy of test results. The temperature of fingertip blood collection should be lower than that of venous blood collection. When choosing fingertip blood collection to obtain blood samples, it often leads to hemolysis, and the blood flow rate is too slow, which can reduce the efficiency of clinical testing. At the same time, fingertip blood collection is greatly affected by capillary blood volume, and cell fluid may mix in during repeated squeezing to obtain blood samples, which can also affect the test results. Therefore, in clinical practice, venous blood collection is generally chosen to reduce the influence of internal and external factors on test results and obtain more accurate test reports.
When collecting blood samples, the blood collection personnel will flexibly choose disposable pinhole blood collection materials based on the subcutaneous fat condition of the tester. For general blood routine tests, it is recommended to use a No. 7 blood collection needle, place the pulse pressure band 5-6cm near the estimated puncture site, adjust the tightness and require the tester to keep their fists tightly clenched, maintain a disinfection diameter of 5cm or more to disinfect the puncture site, and adjust the puncture angle to 40 °. After inserting the blood collection needle into the vacuum tube, the tester can keep their fists relaxed. After blood collection is completed, use a cotton swab to press and stop bleeding for 3 minutes.
In summary, blood routine examination is an important clinical test item. Based on the indicators of blood routine examination, doctors can diagnose the disease more quickly and accurately, improve clinical diagnosis and treatment efficiency, and optimize disease treatment outcomes. For the up and down arrows in the blood routine test report, as long as they do not exceed the specified range, there is no need to be overly nervous.
