During pregnancy there are several tests that are very important to be conducted at regular intervals. These tests assure the health and well being of the mother and the child. The tests that a pregnant woman needs to undergo in the first trimester of pregnancy are as follows.
Here Are First Trimester Tests During Pregnancy:
1. Blood Tests:
Blood test is one of the primary tests conducted during the first trimester of pregnancy. This test includes the identification of blood type, the Rh results and a complete screening for anemia. Blood is a very important aspect when it comes to pregnancy as it affects the overall health of the child too.
This test also includes check for immunity towards rubella, hepatitis B, syphilis, HIV and other sexually transmitted disease too. These tests vary as per the region, backgrounds and racial factors. Test for the exposure of various disease like toxoplasmosis, varicella, sickle cell etc is also conducted. Also the important test regarding the placenta like levels of HCG, hormones secreted by placenta and progesterone are done.
2. Urine Tests:
In early stages of pregnancy, Urine tests are preferred by the clinicians. The urine samples are checked along with any signs of kidney infection and if uncertain about pregnancy, then to confirm the pregnancy by measuring the HCG levels. The urine samples are also collected to monitor the glucose and albumin protein that may show preeclampsia.
3. Genetic Tests:
In the first trimester, the genetic testing is also offered. There are several pros and cons so it is not a compulsory test. It is just to assure whether the baby is genetically normal. There are varieties of genetic tests that undergo blood tests with or without ultrasound for Down syndrome. The blood tests are used in maternal blood are used with ultrasound to measure skin at the back of the fetus’s neck. If the results are positive, the CVS is used.
4. NIPT: Non-Invasive Prenatal Testing
This screening is a cell free DNA test is done within 10 weeks of pregnancy. The test uses a blood sample to identify the amount of free fetal DNA in the mother’s blood. This test can detect 995 of Down syndrome.
5. Chronic Villius Sampling:
This test or screening is conducted if the parents are 35 or older and if the family of the parents has a history of certain disease or have positive indication in non-invasive genetic tests. This is an optional invasive test is conducted between 10-12 weeks of the pregnancy. The CVS can detect and identify many genetic defects like Down Syndrome, sickle cell, anemia, cystic fibrosis, hemophilia etc.
The process in conducting this test includes threading a little catheter through the mother’s cervix or inserting a needle into the mother’s abdomen to get a tissue sample from the placenta. This process does have a 1% risk of miscarriage while it is about 98% accurate in finding out several birth defects. In contrast to the amniocentis, it does not give results in detecting neural tube disorders like spina bifia and anencephaly.
These are the basic tests which are to be conducted in the first trimester after identifying pregnancy. These tests are very important to undergo to assure a safe and healthy nurturing of the fetus. These tests must be undertaken under the supervision and guidance of the doctor or clinican. These tests can give the proper identification of the problems in the mother and the fetus and on the basis of the problem detection, several solutions can be provided.
