What is the blood test for eight months of pregnancy? How to stop bleeding after blood test

During pregnancy, you need to have regular checkups, so blood tests are a very common way to check the body's various indicators. And the items for checkups are different at different stages of pregnancy. So what tests are done when you have a blood test at 8 months of pregnancy?

What is the blood test for eight months of pregnancy?

At 8 months of pregnancy, which is 32 weeks, blood tests are usually done to check whether the pregnant mother has anemia.

Although it is a simple blood draw, many indicators can be detected, such as white blood cell count, hemoglobin concentration, mean hematocrit, platelet count, etc. The doctor will determine whether anemia is present based on the result of hemoglobin concentration.

The hemoglobin concentration range is 115-150g/L, and a concentration below 115g/L is considered anemia.

Another thing to look at is liver function, mainly the level of transaminase. If the value exceeds the standard, it indicates liver damage and liver protection treatment should be performed if necessary.

To check kidney function, we mainly look at blood creatinine. If the value exceeds the standard value by more than 3 times, it indicates kidney function damage.

After 37 weeks of pregnancy, blood will be drawn again. The purpose is to ensure that pregnant women have sufficient blood volume and meet the standard for normal delivery. Therefore, blood routine, coagulation function, liver and kidney function need to be checked.

How to stop bleeding after blood draw

1. Before preparing to have your blood drawn, check if your clothes are wrapped around your upper arm too tightly. Make sure they are loose, which will help blood flow smoothly during blood collection and avoid squeezing your upper arm and making it difficult to stop bleeding.

2. When the doctor pulls out the needle, quickly press the correct position of the needle hole with the entire thumb. Apply force evenly, from large to small. Do not remove the cotton swab to check within two minutes. After pressing steadily for 2 minutes, remove it appropriately to check the needle hole. Some individuals with strong coagulation function have indeed stopped bleeding, but most people still need to continue pressing for 2-3 minutes.

3. When pressing, the arm where the blood is collected cannot be hung with heavy objects. Some girls like to hang a bag on their arm and press with their arm drooped. Be sure not to hold any weight and try to raise it as high as possible.

Why doesn't a blood test show blood type?

The physical examination package does not include blood typing, so when blood is drawn for a physical examination, there are often no blood typing results.

For example, the physical examination packages selected by the unit include the most basic and routine physical examination items, such as a routine blood test and a liver and kidney function test. Among the liver and kidney function tests, only two items are checked, one is alanine aminotransferase and the other is aspartate aminotransferase. Only two items are checked in the kidney function test, one is urea nitrogen and the other is creatinine. These physical examination items are very routine and can basically be said to be the most routine physical examination items. Blood type testing is generally required before surgery or blood transfusion. It is impossible to check this item in a routine examination, and these clinical emergency items are generally rarely involved in the physical examination package.

Blood types are generally divided into A, B, AB, and O. Blood transfusions are generally performed on the basis of the same blood type. Sometimes different blood types can be transfused, such as O type, which is a universal blood type and can be transfused to patients with any blood type; on the contrary, AB type is the most stingy blood type, which can accept any blood type, but can only be provided to AB type patients! There is another less commonly used classification method: RH classification, which is divided into RH negative (-) and RH positive (+). This is generally checked when blood transfusion or blood donation is needed.
