Early pregnancy blood test indicators

What pregnant women need to know in the early stages of pregnancy is the blood test indicators. The first thing everyone needs to do is the relevant examinations in the early stages of pregnancy. You can see whether the hemoglobin neutrophil particles in the body exceed the standard. If you don’t understand, you can consult a doctor, but the specific judgment still needs to be based on the hospital’s examination results.

How to tell the gender of a baby by blood test

If the neutrophil count and neutrophil percentage on the blood routine report of the first prenatal check-up (about three months of pregnancy) are both higher than the reference value, it is definitely a boy. If only one is higher than the reference range, it is likely to be a boy. If both values ​​are within the reference range, it is a girl.

In addition, there is another saying: If the neutrophil particles and hemoglobin on the list are both exceeded, the greater the excess, the greater the chance of a boy.

The above three reference values ​​are roughly the same in every hospital. Even if they are different, they will be marked on the back of the relevant form. Reference value of neutrophil percentage: 45-70% or 50-70%. Reference value for neutrophil count: 2.00-7.00x109/L. Hemoglobin reference value: 115-150g/l.

One of the items is to check whether the neutrophil data (percentage and absolute value) is high. If it is high, it means it is a boy, and if it is normal, it means it is a girl!

The neutrophil count here refers to the percentage and absolute value. Both indicators must be higher than the reference values, then the probability of a boy is high. If both are between the reference values, the possibility of a girl is high. If one of them is high and the other is normal, then it is a suspense baby. The reference data is mainly based on the middle and late pregnancy.

How accurate is fetal gender detection?

The highest accuracy rate for determining the gender of the fetus with a 7-week blood test is 99.9%, so if someone tells you that the accuracy rate is 100%, that is definitely a lie.

Because from the perspective of medical research, there is no such thing as 100%.

Because the fetal DNA concentration begins to stabilize after 7 weeks, it has been scientifically verified that the positive and negative detection rates at 7 weeks and 40 weeks are exactly the same!

Then, you still have to remember an important thing: 7 weeks is definitely not calculated based on the last menstrual period, but based on the embryo length of 10mm detected by B-ultrasound!
