Is blood clot dangerous?

Ask
Hello doctor. I had a blood test at the district hospital, the doctor said that the blood was clotted, so I had to do the test again. I asked the doctor and he said it was okay, and the doctor took a blood sample for testing and said that my blood was damaged. So the doctor asked me if blood clots are dangerous? Looking forward to consulting your doctor help me. Thank you.

Hello, sir. The doctor would like to answer the question: “Is blood clot dangerous? ” is as follows:
When blood is taken for testing, there are many causes: Is the technique of taking blood correct? How are your blood vessels? Is it easy or difficult to get blood? If the doctor's blood vessels are small and sunken, it is very difficult to take, and the blood collection time is prolonged, making the blood more likely to clot. Or get blood, when it is put into a test tube containing anticoagulant but mixed evenly, the blood mixing technique will also be frozen. There are cases where the consistency of the blood increases, making it difficult to collect and mix the blood with anticoagulants, so the blood is also prone to clotting.
I asked and the doctor said it was okay, that means it's okay to take blood again for testing. And the staff who took the sample said that damaged blood means that the blood is clotted, not the blood in your body is damaged.
