Is nt2.6 normal?

I went to the hospital for an nt examination today, and found that the nt value was 2.6 on the report. I have never done this examination before. May I ask the doctor if nt2.6 is normal?

NT2.6 mm is a normal phenomenon. When performing NT inspection, it is normal if the main value does not exceed 3 mm. However, in order to exclude the risk, when the nt is 2.6 mm, you can be further admitted to the hospital for a non-invasive DNA test. If the non-invasive DNA test is also normal, you can continue the pregnancy. During pregnancy, regular pregnancy check-ups should be performed to understand the growth and development of the fetus. In order to meet the growth needs of the fetus during pregnancy, you can eat more protein-rich foods in your diet, such as eggs, milk, silky chicken, black fish, ribs, etc. You can also eat more vitamin-rich foods to speed up food digestion and absorption.
