You’re pregnant. Congratulations! This is an exciting time in your life. But also a time where your health (along with that of your growing baby) will be closely monitored. Here are some of the most basic 1st trimester pregnancy tests you’ll probably have done.
Most common 1st trimester pregnancy tests
During the first antennal visit, your blood type and Rhesus factor will be determined. You can also expect screens for anaemia, immunity to rubella, hepatitis B, syphilis, and HIV to be done. You may also be tested for risk for diseases such as cystic fibrosis and sickle cell anaemia, but this is dependent on your racial, ethnic, and family background. If needed, your doctor will also perform tests for diseases such as toxoplasmosis and varicella, which can cause chickenpox.
Urine tests will become a regular feature during your pregnancy. During the 1st trimester, your doctor or midwife will regularly take urine tests to measure blood glucose and albumin, which can help detect problems such as diabetes, preeclampsia, and high blood pressure during pressure.
Keep in mind that unless you suspect something might be wrong with your baby, these tests aren’t compulsory and might actually cause unnecessary stress on your unborn baby. Some genetic tests rely on blood tests where others use blood tests along with ultrasounds for the best results.
One of the most common genetic tests offered during the 1st trimester is the Down syndrome tests. The test includes the use of ultrasound technology and blood tests to scan for genetic conditions such as Down syndrome.
These tests measure free fetal DNA in the mother’s blood, and they can detect up to 99% of all Down syndrome pregnancies. As well as testing for genetic issues, NIPT screens can also detect chromosomal abnormalities.
Chorionic Villus Sampling
You can get a CVS test if you are older than 35. It is also neccesary if you have a family history of certain diseases. Or you’ve had positive results with other prenatal tests. These invasive tests happen between weeks 10 and 12 of pregnancy and detect genetic defects, sickle cell anaemia, cystic fibrosis, haemophilia, and muscular dystrophy. These tests use tissue samples from the placenta and although they carry a 1% risk of inducing miscarriage, they are 98% accurate on ruling out birth defects.
