Polio is a disease that troubles many parents. First of all, if you have polio, you must go to the hospital for treatment in time. Speaking of going to the hospital for treatment, you must do a lot of tests. Polio blood routine test is one of the common tests for polio patients to understand the changes in blood cells and erythrocyte sedimentation rate. Understand the relevant precautions of polio blood routine test to get better test results.

The most basic requirement for a blood test is fasting, so patients should fast after 8 pm the night before the test, especially after 12 pm. On the morning of the test, patients can only drink boiled water, and are prohibited from drinking milk, juice and other beverages. In order to ensure the effect of the test, patients should avoid eating greasy food, such as fried food, fatty meat, etc., the night before the test, and can eat some light food. You can eat after the blood is collected.

The night before the test, the patient should clean the skin at the blood collection site, preferably both upper limbs. On the day of blood collection, the patient should wear loose-sleeved clothes to expose the elbow vein during blood collection. The clothes should be clean to prevent needle hole infection.

After blood collection, the forearm should be straightened and the hemostatic cotton ball should be pressed tightly with the other hand. Do not lift the cotton ball every few seconds to avoid affecting the hemostatic effect. Press for at least 5 minutes. The patient should not bend the elbow to stop bleeding, nor twist the cotton ball to avoid subcutaneous congestion. To avoid infection, do not let the needle hole get wet within 24 hours of blood collection. If it is accidentally wet, immediately wipe it dry with a clean towel or paper towel without force; if the skin around the needle hole appears cyanotic, apply hot compress with a towel after 24 hours.

The above is the relevant content of the routine blood test for polio. Through the above understanding, you should go to a regular hospital for treatment. Do not blindly avoid medical treatment to avoid delaying the disease.
