The test is an important method for diagnosing diseases. As a result, the accuracy is closely related to the patient’s cooperation. To this end, the correct preparation before the test is the prerequisite for the accurate results. Take the common blood collection test, you need to pay attention:

After eating, a variety of material components in the blood will show temporary changes, which cannot reflect the authenticity of the body. The collection time of fasting blood is generally in the morning, and it can also be 6 hours after a light diet when special needs. Maintain the usual eating habits 2 weeks before the blood test, and take blood at 12 hours after a meal.
Second, it is not advisable to exercise more before taking blood.
One type of exercise is static, that is, the duration is not long, but it has high intensity, such as weightlifting, throwing the ball, etc., and the energy stored in the muscles has little impact on the test. Another type of movement is dynamic, that is, long duration, and small movement intensity, such as long -distance running, swimming, bicycle competitions, etc., need a lot of calories to maintain, which has a greater impact on the test results. Try to avoid it within 2 days before the test.
